Hello
To solve this issue either use "Mark\r\nBond", or "Mark" + Environment.NewLine + "Bond"

I have created a custom datagridviewColumn control containig a TextBox+Button. I want to access the events of these controls directly, for example TextBox_textChanged, Button_MouseHover. following code has been written for this, but it is not working 
DXDataGridViewTextBoxButtonColumn btn = new DXDataGridViewTextBoxButtonColumn();<br />
((DXTextBoxButtonCell)btn.CellTemplate).SSTextBoxButton.Button.Click += new EventHandler(SSTextBoxButton_Enter);<br />
((DXTextBoxButtonCell)btn.CellTemplate).SSTextBoxButton.Enter += new EventHandler(SSTextBoxButton_Enter);<br />
<br />
I have simply shown a messagebox in its event handler.
Can anyone help?
sorry for my bad English.

Hello
Let me get this right!! Your problem is that you made a custom control - TextBox & a Button-, and you want to display it in the header cell?? Or is it in all cells of the column??

Hello
Now I got your problem... Actually custom DatagridView columns are inherited -after some fathers- from DataGridViewElemnt. In that class you will find protected methods called RaiseCellClick(), RaiseCellContentClick(), among other methods to raise the events DatagridView.CellClick event, and DataGridView.CellContentClick. So the control that will handle the events is the DataGridView actually by the above events. If your custom control doesn't fire these events automatically -I don't know how you implemented them!-, so when you see suitable fire them yourself using the Raise methods.

Thanx Nader for your help
public override void InitializeEditingControl(int rowIndex, object<br />
initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle)<br />
{<br />
ase.InitializeEditingControl(rowIndex, initialFormattedValue,<br />
dataGridViewCellStyle);<br />
DXTextBoxButtonColumnEditingControl ctl =<br />
DataGridView.EditingControl as DXTextBoxButtonColumnEditingControl;<br />
if(ctl !=null)<br />
if (this.Value != null)<br />
ctl.SSTextBox.Text = (string)this.Value;<br />
else<br />
ctl.SSTextBox.Text = string.Empty;<br />
}
i want this ctl to be accessed in the form where datagridcolumn will be used.
Thanx

Hello
I'm sorry my reply came very late, but your email notification arrived to my just now!!
You can't acess ctl this way because you've declared it as a local variable in a method. Declare it as a public member in your class, and access it like MyCustomColumn.ctl.Click for the click event as an example.
I don't know if my reply would help you or it came too late, but forgive me.
Regards

da1.Fill(ds, "Autores1")
Dim dv As New DataView(ds.Tables("Autores"))
dv.RowFilter = "Au_ID <= 15"

You can configure it in SQL Server
only two letters away from being an asset
|
|
|
|
|
You can write a WindowsService and make this service start your processes whenever you want (in this case when the DateTime.Minute = 0)..
not an expert suggestion just an idea

*sigh* buy a book, and work through it. You're never going to learn if you come to these forums without the slightest idea of how to apply the things people tell you.
If you double click on a button in the designer you will create an event for the click. What do you want the class to do ? You can have an instance as a member variable, or create a local instance in that class, and call it.
If you have results from the class and want to show them, the easiest way is a messagebox, otherwise you need to create a new form class. If you do this, unless the operator class instance is a member for some reason, I'd do the operation inside that form, so your event just shows the dialog and the form itself performs the operation and shows the result. Otherwise, I'd pass the result through the constructor.
And again, if you don't know what any of that means, buy a book and work through it.
