Iam developing a windows application. I have a dataGridView which has
rows. Inside a row in dataGridView i kept two lines. For doing this
i first did
dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
and kept a new line character in the string
so if i have Mike and Bond to go in separate lines inside one row in dataGridView i would say "Mike"+"\n"+"Bond"
it worked and kept in separate lines but when i double click on the DataGridView row for some weird reason its again keeping back in single line
with some funny character between Mike and Bond
But when i leave the row it again puts back in two separate lines.
Did any body encountered this if yes how to solve this. I want them in Separate line always.
Thanks
Kal

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,
Infact i want to display it in all cells. I have been succeded in doing that, Now i want to handle the event of that control. I have writeen the code in my first post. I dont know that y these events do not get triggered.

say i want to handle the events of button in DataGridViewButtonColumn, tell me how i will do that?
Thanx

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
sorry for my bad English.

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

Maybe Delete() and CancelChanges() on the underlying row ?

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
