DataGridView Custom Column Control Events
-
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 :confused:
DXDataGridViewTextBoxButtonColumn btn = new DXDataGridViewTextBoxButtonColumn(); ((DXTextBoxButtonCell)btn.CellTemplate).SSTextBoxButton.Button.Click += new EventHandler(SSTextBoxButton_Enter); ((DXTextBoxButtonCell)btn.CellTemplate).SSTextBoxButton.Enter += new EventHandler(SSTextBoxButton_Enter);I have simply shown a messagebox in its event handler. Can anyone help?sorry for my bad English.

Hello
MyCustomControl control = new MyCustomControl(); //Includes a public member of type Button called MyButton
control.MyButton.Click += new EventHandler(MyHandler);What's wrong with simplicity??!! Regards:rose:

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?? Regards:rose:

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 calledRaiseCellClick(),RaiseCellContentClick(), among other methods to raise the eventsDatagridView.CellClickevent, andDataGridView.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. Regards:rose: -

Hello I'm sorry my reply came very late, but your email notification arrived to my just now!! You can't acess
ctlthis 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 likeMyCustomColumn.ctl.Clickfor 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:rose:
