This question builds off of this question. What I am doing is attempting to add a DateTimePicker control to a contextmenustrip using ToolStripControlHost. What is odd is the first time I select it in the contextmenu it shows at the location (0,0)
When I hover back to the option again, it displays at the right location.
I can't find where its setting the location. I've tried setting the location of the control being added but does nothing.
public SampleProgram()
{
IntializeComponent();
DateTimePicker sampleDatePicker = new DateTimePicker();
sampleDatePicker.TextChanged += new EventHandler(dateTimePicker_OnTextChange);
sampleDatePicker.Format = DateTimePickerFormat.Short;
datagridview1.Controls.Add(sampleDatePicker);
}
private void datagridview1_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.ColumnIndex != -1 && e.RowIndex != -1 && e.Button == MouseButtons.Right)
{
datagridview1.ContextMenuStrip = new ContextMenuStrip();
datagirdview1.ContextMenuStrip.Items.Clear();
Get_Alphabetical_User_Groups(datagridview1.ContextMenuStrip, SampleContextMenu_Action);
datagridview1.ContextMenuStrip.Items.Add(new ToolStripSeparator());
GetStatusList(datagridview1.ContextMenuStrip, false, SampleContextMenu_Action);
datagridview1.ContextMenuStrip.Items.Add(new ToolStripSeparator());
GetDatePicker(datagridview1.ContextMenuStrip, SampleContextMenu_Action);
datagridview1.ContextMenuStrip.Items.Add("Copy Cell Data", Resources.blank, SampleContextMenu_Action);
datagridview1.ContextMenuStrip.Show(Cursor.Position.X, Cursor.Position.Y);
}
}
private void GetDatePicker(ContextMenuStrip dateMenu, EventHandler MenuOption_Click_Handler)
{
Point mouseloc = Cursor.Position;
sampleDatePicker.Location = mouseloc;
var datePicker = new ToolStripControlHost(sampleDatePicker);
datagridview1.ContextMenuStrip.Items.Add(new ToolStripMenuItem("Set Followup Date to", Resources.calendar_edit, datePicker));
}
Any help is much appreciated!
Don't add the control to the DataGridView's Control collection. It doesn't belong there:
// datagridview1.Controls.Add(sampleDatePicker);

I am trying to create such that when I click RMB a drop down list/menu is created. My definition of the drop down menu will be attached below. I am stuck at the event handler, I filtered if the even is a LMB or RMB and then I am having issues from here.
Firstly my requirement, I have designed a map when I click RMB I need a drop down so I can select suitable options.
My Drop down definition
this.UserControl_MissionPlan_MapPanel_MourseRightClick = new ComboBox();
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Location = new System.Drawing.Point(700, 700);
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Size = new System.Drawing.Size(120, 120);
this.UserControl_MissionPlan_MapPanel_MourseRightClick.DropDownStyle = ComboBoxStyle.DropDownList;
this.UserControl_MissionPlan_MapPanel_MourseRightClick.MaxLength = 5;
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Items.Add(1);
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Items.Add(2);
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Items.Add(3);
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Items.Add(4);
this.UserControl_MissionPlan_MapPanel_MourseRightClick.Items.Add(5);
And finally my event handler
private void UserControl_MissionPlan_MapPanel_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
double WaypointLatitude = UserControl_MissionPlan_MapPanel.FromLocalToLatLng(e.X, e.Y).Lat;
double WaypointLongitude = UserControl_MissionPlan_MapPanel.FromLocalToLatLng(e.X, e.Y).Lng;
// MessageBox.Show(Convert.ToString(WaypointLatitude));
// MessageBox.Show(Convert.ToString(WaypointLongitude));
// GMapOverlay NavigationWayPoint = new GMapOverlay("NavigationWayPoint");
// GMapMarker WayPoint = new GMarkerGoogle(new PointLatLng(WaypointLatitude, WaypointLongitude), GMarkerGoogleType.orange_small);
// NavigationWayPoint.Markers.Add(WayPoint);
// UserControl_MissionPlan_MapPanel.Overlays.Add(NavigationWayPoint);
}
else if (e.Button == System.Windows.Forms.MouseButtons.Right)
{
// MessageBox.Show("Right Mouse button Mouse clicked");
}
}
I am unable to show tooltips on ListView subitems. Involved implementation is:
ListView sqlView = new ListView() { Dock = DockStyle.Fill, View = View.Details, MultiSelect = true, FullRowSelect = true, HeaderStyle = ColumnHeaderStyle.Nonclickable, GridLines = true };
...
sqlView.ShowItemToolTips = true;
sqlView.MouseMove += sqlView_MouseMove;
...
// filled in foreach, don't worry it's correct here ;)
item.SubItems[columnIndex].Text = "✔";
item.SubItems[columnIndex].Tag = ("via: '" + sqlEntry.Login + "'");
Mouse event handler method:
void sqlView_MouseMove(object sender, MouseEventArgs e)
{
ListView sqlView = ((ListView)sender);
ListViewItem item = sqlView.GetItemAt(e.X, e.Y);
ListViewHitTestInfo info = sqlView.HitTest(e.X, e.Y);
if (item != null && info.SubItem != null && info.SubItem.Tag != null)
{
ToolTip tt = new ToolTip();
//tt.ShowAlways = true; - no effect
//tt.Active = true; - no effect
tt.SetToolTip(sqlView, (String)info.SubItem.Tag);
}
}
Events are firing. Subitems Tags are filled properly. No Tooltip shown. Why?
Thx for help.
Don't create a new ToolTip() each time through. Just create one and reuse it.
I've been trying to solve my issue for quite a while and to be honest am getting nowhere. What i would like is when the user clicks the 'top' button on my panel it automatically goes to the top( and swaps with the one there.) and when they click the bottom button it automatically goes to the bottom. I'm setting the index panel manually but of course this doesnt work because its only viable for one panel (i have ten). Greatly appreciate some help in finding a method that can send the panel to the top of the stack regardless of its position.
Here is a image (basic) to help understand
Control ctrlToMove = (Control)this.bookControls[bookName];
int ctrlToMoveIndex = bookPanel.Controls.IndexOf(ctrlToMove);
int ctrlToSwapIndex = ctrlToMoveIndex - 5;
Control ctrlToSwap = bookPanel.Controls[ctrlToSwapIndex];
this.bookPanel.Controls.SetChildIndex(ctrlToMove, ctrlToSwapIndex);
this.bookPanel.Controls.SetChildIndex(ctrlToSwap, ctrlToMoveIndex);
Based on your drawing, I made a UserControl with a button on it:
void uc_ButtonClicked(object sender, EventArgs e) {
UserControl1 uc = sender as UserControl1;
if (uc != null) {
int childIndex = flowLayoutPanel1.Controls.GetChildIndex(uc);
if (childIndex > 0) {
UserControl1 ucTop = flowLayoutPanel1.Controls[0] as UserControl1;
flowLayoutPanel1.Controls.SetChildIndex(uc, 0);
flowLayoutPanel1.Controls.SetChildIndex(ucTop, childIndex);
}
}
}
According to your picture you have one control per row in panel. Thus I suggest you to use TableLayoutPanel instead of FlowLayoutPanel. Also I'd create user control for items in panel. E.g. it will have name PriorityUserControl and four buttons to increase, decrease, maximize, minimize it's 'priority' (I placed buttons horizontally just to save place on screen):
Next, create four events in this user control:
public event EventHandler PriorityMaximized;
public event EventHandler PriorityIncreased;
public event EventHandler PriorityDecreased;
public event EventHandler PriorityMinimized;
And rise appropriate event when button clicked:
private void topButton_Click(object sender, EventArgs e)
{
if (PriorityMaximized != null)
PriorityMaximized(this, EventArgs.Empty);
}
That's it. We have user control which tells whether it want to move up or down. Now add user controls to TableLayoutPanel (either manually or dynamically) and subscribe same event handlers of these four events to ALL user controls. Something like:
// create user control and attach event handlers
PriorityUserControl control = new PriorityUserControl();
control.PriorityMaximized += priorityUserControl_PriorityMaximized;
control.PriorityMinimized += priorityUserControl_PriorityMinimized;
control.PriorityIncreased += priorityUserControl_PriorityIncreased;
control.PriorityDecreased += priorityUserControl_PriorityDecreased;
// add another row to table
panel.RowStyles.Add(new RowStyle(SizeType.AutoSize));
panel.RowCount = panel.RowStyles.Count;
// add control table layout panel
panel.Controls.Add(control);
panel.SetRow(control, panel.RowCount - 1);
Good. All you should do now is implement these event handlers. It's simple. E.g. decreasing priority (i.e. moving down):
private void priorityUserControl_PriorityDecreased(object sender, EventArgs e)
{
// sender is a control where you clicked Down button
Control currentControl = (Control)sender;
// get position in panel
var position = panel.GetPositionFromControl(currentControl);
// just to be sure control is not one at the bottom
if (position.Row == panel.RowCount - 1)
return;
// we want to switch with control beneath current
Control controlToSwitch = panel.GetControlFromPosition(0, position.Row + 1);
// move both controls
panel.SetRow(currentControl, position.Row + 1);
panel.SetRow(controlToSwitch, position.Row);
}
Now implementation of maximizing priority (i.e. moving to top):
private void priorityUserControl_PriorityMaximized(object sender, EventArgs e)
{
Control currentControl = (Control)sender;
var position = panel.GetPositionFromControl(currentControl);
if (position.Row == 0 || panel.RowCount < 2)
return;
Control topControl = panel.GetControlFromPosition(0, 0);
panel.SetRow(currentControl, 0);
panel.SetRow(topControl, position.Row);
}
I believe you will create rest two handlers by yourself.
The key of what you want is setting up a clear and extendable algorithm capable to deal with the different positions of the Panels. Here you have a simple code showing certain approach to this problem:
public partial class Form1 : Form
{
int[] panelLocations;
Point[] pointLocations;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
panelLocations = new int[5];
pointLocations = new Point[5];
panelLocations[1] = 1;
panelLocations[2] = 2;
panelLocations[3] = 3;
pointLocations[1] = new Point(panel1.Left, panel1.Top);
pointLocations[2] = new Point(panel2.Left, panel2.Top);
pointLocations[3] = new Point(panel3.Left, panel3.Top);
}
private void relocate(int curPanel, bool goTop)
{
int curLoc = panelLocations[curPanel];
int newLoc = curLoc - 1;
if (!goTop)
{
newLoc = curLoc + 1;
}
if (newLoc < 1) newLoc = 3;
if (newLoc > 3) newLoc = 1;
if (newLoc != curLoc)
{
int otherIndex = Array.IndexOf(panelLocations, newLoc);
panelLocations[curPanel] = newLoc;
relocatePanel(curPanel);
panelLocations[otherIndex] = curLoc;
relocatePanel(otherIndex);
}
}
private void relocatePanel(int curIndex)
{
if (curIndex == 1)
{
panel1.Location = pointLocations[panelLocations[1]];
}
else if (curIndex == 2)
{
panel2.Location = pointLocations[panelLocations[2]];
}
else if (curIndex == 3)
{
panel3.Location = pointLocations[panelLocations[3]];
}
}
private void buttonTop1_Click(object sender, EventArgs e)
{
relocate(1, true);
}
private void buttonBottom1_Click(object sender, EventArgs e)
{
relocate(1, false);
}
}
Open a new project, add 3 panels (Panel1, Panel2 and Panel3... better put different background colors) and include two buttons (buttonUp and buttonDown). This code will make the Panel1 to go up and down (by changing its position with the other panels).
The idea is pretty simple: at the start you store the positions of all the Panels in an array. In another array, you store where each panel is located every time (1 is the original position of Panel1, etc.).
It is a quite simple code which you can improve and extend as much as required, but the idea is pretty reliable and you can use it in any case: a set of fixed positions through which the panels will be moving.
I have a ListView control in Details view as that (the view that shows the list as a grid)
mListView.View = View.Details;
mListView.mLVSelectedObject.ShowItemToolTips = true;
ListViewItem listViewItem = mListView.Items.Add(lValue.Name);
listViewItem.ToolTipText = "AAAAAAAAAAAAAAAAA";
The issue is that the tooltip only shows up when the cursors is over the first listview's column but not for the rest o them. I want to know if there's anyway to make it appear "easly" ?
After some research. I've solved the issue this way, but I'm still wondering if there is another way to do that avoiding EventHandlers;
ToolTip mTooltip;
Point mLastPos = new Point(-1, -1);
private void listview_MouseMove(object sender, MouseEventArgs e)
{
ListViewHitTestInfo info = mLV.HitTest(e.X, e.Y);
if (mTooltip == null)
mTooltip = new ToolTip();
if (mLastPos != e.Location)
{
if (info.Item != null && info.SubItem != null)
{
mTooltip.ToolTipTitle = info.Item.Text;
mTooltip.Show(info.SubItem.Text, info.Item.ListView, e.X, e.Y, 20000);
}
else
{
mTooltip.SetToolTip(mLV, string.Empty);
}
}
mLastPos = e.Location;
}
When I clicked on a control,
How to get cursor position relative to upper left corner of a (winforms) control ?

PS:
I'm asking on context of tooltip "show" method which need that coordinates ..
This is my code to set tooltips on a composite control, might give you a clue (LED derivers from UserControl):
public LED()
{
InitializeComponent();
m_Image = global::AdvAdmittance.Controls.Properties.Resources.ledgray_small;
m_ToolTip = new ToolTip();
m_ToolTip.AutoPopDelay = 5000;
m_ToolTip.InitialDelay = 1000;
m_ToolTip.ReshowDelay = 500;
m_ToolTip.ShowAlways = true;
m_LedPictureBox.MouseHover += new EventHandler(m_LedPictureBox_MouseHover);
m_LedPictureBox.MouseLeave += new EventHandler(m_LedPictureBox_MouseLeave);
m_LedPictureBox.Click += new EventHandler(m_LedPictureBox_Click);
}
void m_LedPictureBox_MouseHover(object sender, EventArgs e)
{
if (m_ToolTipText != string.Empty)
{
Point toolTipPoint = this.Parent.PointToClient(Cursor.Position);
toolTipPoint.Y -= 20;
m_ToolTip.Show(m_ToolTipText, this.Parent, toolTipPoint);
}
}
void m_LedPictureBox_MouseLeave(object sender, EventArgs e)
{
m_ToolTip.Hide(this.m_LedPictureBox);
}
Ahh, Thanks for an answer.
All I need is a PointToClient method.
I hope (maybe) it will be useful for other people, here "my" code.
I took almost all code from http://support.microsoft.com/kb/322634 and modified three lines:
void treeView1_MouseMove(object sender, MouseEventArgs e)
{
// Get the node at the current mouse pointer location.
TreeNode theNode = this.treeView1.GetNodeAt(e.X, e.Y);
// Set a ToolTip only if the mouse pointer is actually paused on a node.
if ((theNode != null))
{
// Verify that the tag property is not "null".
if (theNode.Tag != null)
{
// Change the ToolTip only if the pointer moved to a new node.
if (theNode.Tag.ToString() != this.toolTip1.GetToolTip(this.treeView1))
{
//this.toolTip1.SetToolTip(this.treeView1, theNode.Tag.ToString());
Point c = System.Windows.Forms.Cursor.Position;
Point p = treeView1.PointToClient(c);
this.toolTip1.Show(theNode.Tag.ToString(), treeView1, p);
}
}
else
{
this.toolTip1.SetToolTip(this.treeView1, "");
}
}
else // Pointer is not over a node so clear the ToolTip.
{
this.toolTip1.SetToolTip(this.treeView1, "");
}
}
