How can I give separate events to buttons in datagridview?

dgvaciklamaBtn.Name = "Açıklama";
dgvaciklamaBtn.HeaderText = "Açıklama";
dgvkartvizitBtn.HeaderText = "Kartvizit";
dgvaciklamaBtn.Name = "Oku";
dgvaciklamaBtn.Text = "Oku";
dgvkartvizitBtn.Text = "Görüntüle";
dgvaciklamaBtn.UseColumnTextForButtonValue = true;
dgvkartvizitBtn.UseColumnTextForButtonValue = true;
dgvaciklamaBtn.DefaultCellStyle.BackColor = Color.Red;
dgvkartvizitBtn.DefaultCellStyle.BackColor = Color.Red;
dgvaciklamaBtn.DefaultCellStyle.SelectionBackColor = Color.White;
dgvkartvizitBtn.DefaultCellStyle.SelectionBackColor = Color.White;
dgvaciklamaBtn.Width = 70;
dgvkartvizitBtn.Width = 70;
firmalardtgview.DataSource = firmalartablo;
firmalardtgview.Columns[0].Width = 30;
firmalardtgview.Columns.Add(dgvaciklamaBtn);
firmalardtgview.Columns.Add(dgvkartvizitBtn);
firmalardtgview.Refresh();
private void firmalardtgview_CellContentClick(object sender, DataGridViewCellEventArgs e){
var senderGrid = (DataGridView)sender;
if (e.ColumnIndex == firmalardtgview.Columns["Açıklama"].Index)
{
string firmaid = firmalardtgview.CurrentRow.Cells["ID"].Value.ToString();
int index = firmaidler.IndexOf(firmaid);
MessageBox.Show(aciklamalar[index].ToString(), "Açıklama");
}
}
I want to make separate codes for read and explanation. Should I create separate events? Can it be solved with an if query? i am getting error like this

I solved the problem by taking the index number of the column and comparing it with the index number of the selected column.
It would be better if there is another shortcut. This is how it works.
string kartismi="";
if (e.ColumnIndex == 0)
{
string firmaid = firmalardtgview.CurrentRow.Cells["ID"].Value.ToString();
int index = firmaidler.IndexOf(firmaid);
MessageBox.Show(aciklamalar[index].ToString(), "Açıklama");
}
else if (e.ColumnIndex == 1)
{
string firmaid = firmalardtgview.CurrentRow.Cells["ID"].Value.ToString();
int index = firmaidler.IndexOf(firmaid);
SqlBaglanti.baglanti.Open();
SqlCommand kartvizitisimi = new SqlCommand("SELECT kartvizit_ismi FROM kartvizitler WHERE kartvizit_id=#kid", SqlBaglanti.baglanti);
kartvizitisimi.Parameters.AddWithValue("#kid", kartvizitIDler[index]);
SqlDataReader dr = kartvizitisimi.ExecuteReader();
if(dr.Read())
{
kartismi = dr["kartvizit_ismi"].ToString();
}
SqlBaglanti.baglanti.Close();
Process.Start(Path.Combine(Application.StartupPath,"Kartvizitler",kartismi));
}

C# Create Tracks Parents which Depend on Children

I'm trying to create tracks of Parent that have more than a child and put theme in dynamic ListBox
i have this ParentActivity table"
tblParentActivity
and I want to make tracks depend on ParentActivity table to be in ListBox like this:
Tracks in ListBox
the code so far:
private void TrackingActivity(long ParentActivityID)
{
DataTable dtActiveChild = objA.SelectActivityChild(ParentActivityID);
ListBox lstBox = new ListBox();
lstBox.ID = "lstTrack" + ParentActivityID.ToString();
lstBox.Width = 200;
pnlTrack.Controls.Add(lstBox);
for (int i = 0; i < dtActiveChild.Rows.Count; i++)
{
long ActivityChildID = Convert.ToInt64(dtActiveChild.Rows[i]["ActivityID"].ToString());
string ActivityChildName = dtActiveChild.Rows[i]["ActivityName"].ToString();
lstBox.Items.Add(new ListItem (ActivityChildName.ToString(),ActivityChildID.ToString()));
DataTable dtBrotherActivity = objA.selectBrotherActivity(ActivityChildID);
if (dtBrotherActivity.Rows.Count > 0)
{
TrackingActivity(ActivityChildID);
}
}
}
for example ParentActivityID=1;
selectBrotherActivity is query to get another child of it parent
it gave me distribution like this:
|1|2 3|4 5|7|9|10|7|9|10|6|8|9|10|
which || means ListBox

Ok thanks to everyone I found it:
protected void btnCreateTrack_Click(object sender, EventArgs e)
{
ListBox lstBoxParent = new ListBox();
lstBoxParent.ID = "lstTrack1";
lstBoxParent.Width = 200;
lstBoxParent.Height = 200;
pnlTrack.Controls.Add(lstBoxParent);
TrackingActivity(1, lstBoxParent );
}
private void TrackingActivity(long ParentActivityID, ListBox lstBoxParent)
{
chk:
DataTable dtActiveChild = objWFAI.SelectActivityChild(ParentActivityID);
string ActivityName = objWFA.CurrentActivityName(ParentActivityID);
lstBoxParent.Items.Add(new ListItem(ActivityName, ParentActivityID.ToString()));
for (int i = dtActiveChild .Rows.Count - 1; i >= 0; i--)
{
long ActivityChildID = Convert.ToInt64(dtActiveChild .Rows[i][" ActivityID"].ToString());
if (i != 0)
{
ListBox lstBoxChild = new ListBox();
lstBoxChild.ID = "lstTrack" + ActivityChildID.ToString();
lstBoxChild.Width = 200;
lstBoxChild.Height = 200;
pnlTrack.Controls.Add(lstBoxChild);
for (int p = 0; p < lstBoxParent.Items.Count; p++)
{
lstBoxChild.Items.Add(new ListItem(lstBoxParent.Items[p].Text, lstBoxParent.Items[p].Value));
}
TrackingActivity(ActivityChildID, lstBoxChild);
}
else
{
ParentActivityID = ActivityChildID ;
goto chk;

how to create multiple column tree view with image

i have a problem. i am using the BrightIdeasSoftware.TreeListView to create treeview in my windows form and i also take the reference of How to create a MultiColumn treeview like this in C# Winforms app but i am not success to create this. Can you please tell me what i am doing mistake to create the treeview. The complete description is below.
i want to add the dynamic collapsible Panel and into this want to add tree in this.
The data will display into the panel according the collapsible panel header id .
i have a parent id and that can have multiple child.
Status Column will display one image
below is my code that i am using to create the treeview

DataGridView not showing values in runtime created columns

I´m having a really wierd issue. I assign to my DataGridView a list of entities as a DataSource. I create some columns in runtime, and then, for each Row in the DataGridView, I complete the values of that new columns base on some values of some columns of the row.
The code works fine, because I´m displaying that same DataGridView in other forms. But in this new UserControl, it seems that it´s not showing any values on that new columns.
The wierd thing, is that the values are actually there, because when I do the foreach row loop, I have some acumulators int objects that shows the values in a textbox, and the values are correct.
I used a try and catch to see if something was wrong, but everything is fine.
I attached an image of what I´m getting.
Those two highlighted textboxes are the one that acummulates the values of those two columns..
As I said, the same code is working fine in other forms. Just in case, this UserControl is added to a panel in a form.
This is the code I use for the DataGridView:

You can see that the DataGridView has a column with an eye. If you click the eye, you can see that entity in another form. If you change the entity state in that form, it returns a value (borrado) with true if changes has been made, or false if no change has been made.
If changes were detected, then I call the above method again. Magically, it shows all that missing values!
private void dgv_Prestamos_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex != -1)
{
if (e.ColumnIndex == dgv_Prestamos.Columns["ver_prestamo"].Index)
{
frm_Ver_Prestamo ver_prestamo = new frm_Ver_Prestamo();
ver_prestamo.prestamo_seleccionado = (Prestamo)dgv_Prestamos.Rows[e.RowIndex].DataBoundItem;
ver_prestamo.db = db;
ver_prestamo.ShowDialog();
if (ver_prestamo.borrado == true)
{
dgv_Prestamos.DataSource = null;
Cursor.Current = Cursors.WaitCursor;
Actualizar_grilla_prestamos();
Cursor.Current = Cursors.Default;
}
}
}
}
ver_prestamo is the form that shows the entity. I don´t know what make that work, the only difference is that I do a DataSource = null before. But I do that in the method anyways..

Have you tried moving the dgv_Prestamos.DataSource = lista_prestamos; to the bottom of Actualizar_grilla_prestamos.
I think that it is doing the binding when you set the datasource and can't see the columns you have created afterward.

"Construct the grid, set the DataSource, then change the appearances in the DataBindingComplete event." - glace

how to add items to TreeViewAdv in multi-column mode with winforms

I was playing around with this control called TreeViewAdv. I've already added the control and added couple of columns trying to see how it works. but till now when I add items to the control all I get is empty nodes. the example provided with the control is not clear at all and it just gave me headaches when I try to figure out how the data is being added to it. anyway here is what I've done so far and I hope that someone can guide me to the right direction.
TreeModel _model = new TreeModel();
treeViewAdv1.Model = _model;
treeViewAdv1.BeginUpdate();
for (int i = 0; i < 20; i++)
{
Node parentNode = new Node("root" + i);
_model.Nodes.Add(parentNode);
for (int n = 0; n < 2; n++)
{
Node childNode = new MyNode("child" + n);
parentNode.Nodes.Add(childNode);
}
}
treeViewAdv1.EndUpdate();
anyway, all I'm getting is empty nodes and I really can't figure out how to add data to the other columns... any help would be appreciated...

Obviously this questions is old, but I was unable to find any answers to this question, so I figured I would try to save someone some future frustration.
To get multiple columns to display, first change the UseColumns property to true.
Then add desired columms to the Columns collection property.
Next using the NodeControls collection property to create a list of the types of data that will be shown, and how they should be formatted (Checkbox, TextBox, etc). Make sure to set 1) the DataPropertyName (will be used later), 2) the ParentColumn (to show which column in the treeView is supposed to show the data.
Finally, create a new class inheriting from the Node class, and add a public property with the same name as each NodeControl. Then when adding Nodes, use your new class with the correct value.
private class ColumnNode: Node
{
public string NodeControl1=""; // This sould make the DataPropertyName specified in the Node Collection.
public string NodeControl2 = "";
public string NodeControl3 = "";
public ColumnNode(string nodeControl1, string nodeControl2, int nodeControl3)
{
NodeControl1 = nodeControl1;
NodeControl2 = nodeControl2;
NodeControl3 = nodeControl3.ToString();
}
}
Then when adding the
TreeModel _model = new TreeModel();
_treeViewAdv.Model = _model;
_treeViewAdv.BeginUpdate();
for (int i = 0; i < 20; i++)
{
Node parentNode = new ColumnNode("root" + i, "",0);
_model.Nodes.Add(parentNode);
for (int n = 0; n < 2; n++)
{
Node childNode = new ColumnNode("child" + n,"Further Information",1);
parentNode.Nodes.Add(childNode);
}
}
_treeViewAdv.EndUpdate();
For reference, the designer code for the treeViewAdv in this case would look like this:

It seems as though the price of entry for using this fantastic control is hours, and hours, of head scratching frustration.
This is what you need to do:
private void Form1_Load(object sender, EventArgs e)
{
TreeModel _model = new TreeModel();
treeViewAdv1.Model = _model;
treeViewAdv1.BeginUpdate();
for (int i = 0; i < 20; i++)
{
Node parentNode = new Node("root" + i);
_model.Nodes.Add(parentNode);
for (int n = 0; n < 2; n++)
{
Node childNode = new Node("child" + n);
parentNode.Nodes.Add(childNode);
}
}
NodeTextBox ntb = new NodeTextBox();
ntb.DataPropertyName = "Text";
this.treeViewAdv1.NodeControls.Add(ntb);
treeViewAdv1.EndUpdate();
}

Just in case you're still struggling with the issue, or anyone else is having the same trouble: the solution to empty nodes is to assign a view component to tree.
TreeViewAdv uses MVC, and it requires that you assign a view, though this is not obvious from the example project. NodeTextBox class under NodeControls folder in the source of the TreeViewAdv is one of the viewers you can use. You need to add it to your form and connect it to tree control through its DataPropertyName attribute like this:
this._tBox.DataPropertyName = "Text";
where _tBox is the NodeTextBox instance. Needless to say, I've just lost hours figuring this out. Hope it helps someone else.

You need to instantiate your columns first, then attach them to the TreeView. After all add new cells in all columns at same cell index.
Hope to help
