Cath,
As for the argument, you can use the buttons CommandArgument collection to
pass information back to the handler.
Let me know if you need more help with this.

| Cath,
|
| Before you add the button (using Controls.Add), set the event handler to
| the specific event you need. For example:
|
| C#
| btnMyButton.Text = "My Button";
| btnMyButton.ID = "btnMyButton";
| //
| // other properties for the button
| //
| btnMyButton.Click += new System.EventHandler(this.myButtonHandler_Click);
| // add button to location using "Controls.Add"
|
| VB
| btnMyButton.Text = "My Button"
| btnMyButton.ID = "btnMyButton"
| '
| ' other properties for the button
| '
| AddHandler btnMyButton.Click, AddressOf Me.myButtonHandler_Click)
| ' add button to location using "Controls.Add"
|
|
| The event handler for myButtonHandler would look like the following:
|
| C#
| private void myButtonHandler_Click(object sender, System.EventArgs e)
| {
| // btnTemp will be the button clicked by the user
| Button btnTemp = ((Button)sender);
| // perform any actions you need based on the button click
| }
|
| VB
| Private Sub myButtonHandler_Click(ByVal sender As System.Object, ByVal e
As
| System.EventArgs)
| ' btnTemp will be the button clicked by the user.
| Dim btnTemp As Button = CType(sender, Button)
| ' perform any actions you need based on the button click
| End Sub
|
| It is important that you give an ID to the dynamic controls. You will
not
| be able to reliably determine what control performed the postback unless
| you set the ID property.
|
| Hope this helps,
|

| | I dynamically created several buttons.... How do I set a common handler
| for
| | all of them, passing 1 argument? What's a sample code for that?
| |
| | Thanks.
