I am trying to place Usercontrols on a flowlayout panel that act as a listview in C# (windows forms) . How can I implement selecting items here ?
Click event is not working when the user clicks on the controls of Usercontrol..
Any ideas ?
private void flowLayoutPanel1_ControlAdded(object sender, ControlEventArgs e)
{
e.Control.Click += new EventHandler(Clicked);
}
private void Clicked(object sender, EventArgs e)
{
//click event code goes here
}

how to get smartphone like scrolling for a winforms touchscreen app ( scrolling panel )
i have a problem with the solution. it only works if i click on the panel directly and scroll. If i have elements like labels/textboxes all over the place it doesnt work. I would need to click in between the Elements so i touch the panel directly. So how would i now solve this? Add a Mouse Move/Down Method on ALL elements i have within the panel?
Use the same event for the main panel for all in-panel controls.
panel1.MouseDown += innerpanel_MouseDown;
panel1.MouseMove += innerpanel_MouseMove;
panel1.MouseUp += innerpanel_MouseUp;
foreach(Control ctr in panel1.Controls)
{
ctr.MouseDown += innerpanel_MouseDown;
ctr.MouseMove += innerpanel_MouseMove;
ctr.MouseUp += innerpanel_MouseUp;
}
Events
private void innerpanel_MouseDown(object sender, MouseEventArgs e)
{
//implementation
Control ctr = (Control)sender;
MessageBox.Show(ctr.Name);
}
private void innerpanel_MouseMove(object sender, MouseEventArgs e)
{
//implementation
}
private void innerpanel_MouseUP(object sender, MouseEventArgs e)
{
//implementation
}
Just keep in mind that if you have a button in the control panel, the button click event will run and any control that has a click event.
I have Windows Form named Form1 and inside I have a dynamic SplitContainer named splitcontainer.
I want to know which panel is selected when the mouse is clicked at runtime.
I tried to use mouseclick event in the splitContainer properties but I haven't succeed.
You need to bind to the MouseClick events of the panel inside the split container.
I added a container called "splitContainer1" with 2 panels, Panel1 and 2
I wired up the below events and it seems to work
private void splitContainer1_Panel1_MouseClick(object sender, MouseEventArgs e)
{
MessageBox.Show("Panel1");
}
private void splitContainer1_Panel2_MouseClick(object sender, MouseEventArgs e)
{
MessageBox.Show("Panel2");
}
After your further comments, I've edited the below to show how to manually bind the mouse click events of the 2 panels of your dynamically added container.
private void splitContainerHorizontalToolStripMenuItem_Click(object sender, EventArgs e)
{
SplitContainer spltcnt = new SplitContainer();
spltcnt.Dock = DockStyle.Left;
spltcnt.Orientation = Orientation.Horizontal;
spltcnt.SplitterWidth = 4;
spltcnt.Visible = true;
spltcnt.Size = new System.Drawing.Size(731, 615);
spltcnt.BorderStyle = BorderStyle.Fixed3D;
spltcnt.SplitterDistance = 351;
//Manually bind the mouse click events.
spltcnt.Panel1.MouseClick += Panel1OnMouseClick;
spltcnt.Panel2.MouseClick += Panel2OnMouseClick;
Controls.Add(spltcnt);
}
private void Panel1OnMouseClick(object sender, MouseEventArgs mouseEventArgs)
{
MessageBox.Show("Panel1");
}
private void Panel2OnMouseClick(object sender, MouseEventArgs mouseEventArgs)
{
MessageBox.Show("Panel2");
}
You can of course call the mouse click handler methods anything you like.
Thanks
i need to hide a ListBox when I focus out a textbox. if i click on a different control or use Tab key then the textbox's "Leave" event occurs. But if I click inside the form, on any free space, then focusout doesn't happen. i saw something called mouse capture but i cant implement it.
i tried this:
private void txtProduct_Enter(object sender, EventArgs e)
{
listProduct.Show();
UIElement el = (UIElement)sender;
el.CaptureMouse();
}
private void MouseClickedElseWhere(object sender, MouseEventArgs e)
{
if (e.Clicks >= 1)
{
txtProduct_Leave(sender, new EventArgs());
}
}
private void txtProduct_Leave(object sender, EventArgs e)
{
listProduct.Hide();
}
but obviously it shows error. how do i achieve this? any help?
I had to make click event for my groupboxes even if groupbox doesnt have a click event by default.
//my_page.designer.cs
this.groupBox2.Click += new System.EventHandler(this.groupBox2_clicked);
//my_page.cs
private void groupBox2_clicked(object sender, EventArgs e)
{
listProduct.Hide();
}
I have many controls in my form. for example 120 labels in one panel. and i want when user clicked on each label just call same function with same parameter.
Now i used like this :
private void label67_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
private void label66_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
private void label65_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
private void label64_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
now can i make easy way to call ChangeToTextbox function when user clicked in any label?
Add the same OnClick handler for all labels on the panel:
private void Form1_Load(object sender, EventArgs e)
{
panel1.Controls.OfType<Label>().ToList().ForEach(l => l.Click += label_Click);
}
private void label_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
Find all your controls then just add the handler via code;
List<Control> controls = GetAllMyControls();
foreach(Control control in controls)
{
control.OnClick += (o, e) => { ChangeToTextBox(o); }
}
The syntax should be very similar for both web and winform solutions.
It can be easily achieved by using following approach: Pls give a try,
1) Go to Windows Forms Designer and click the first Label control to select it. Then hold down the CTRL key while you click each of the other labels to select them. Be sure that every label is selected.
2) Then go to the Events page in the Properties window. Scroll down to the Click event, and type label_Click in the box
3) Press ENTER. The IDE adds a Click event handler called label_Click() to the code, and hooks it to each of the labels.
private void label_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}

To determine the content of my context menu I need to detect when the user clicks into the blank area of a treeview.
But, neither the Click nor the MouseClick events fire.
Is it possible to achieve the desired functionality by deriving from TreeView?
If not, what can I do?
You can use the MouseDown event, that fires even in the empty area.
private void treeView1_MouseClick(object sender, MouseEventArgs e)
{
// MessageBox.Show("treeView1_MouseClick");
}
private void treeView1_Click(object sender, EventArgs e)
{
// MessageBox.Show("treeView1_Click");
}
private void treeView1_MouseDown(object sender, MouseEventArgs e)
{
MessageBox.Show("treeView1_MouseDown");
}
