javascript with asp.net

[raju]

Hai,
I am new to ASP.NET, in my application, datagird, itemtemplate, i
am having delete button. If i click that button, I am calling
DeleteCommand,
in that procedure i written the code as given below.

Protected Sub dlTask_DeleteCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataListCommandEventArgs ) Handles
dlTask.DeleteCommand
Dim obutton As Button
obutton = CType(e.Item.FindControl("btnDelete"), Button)
obutton.Attributes.Add("onClick", "alert('Do you want to
Delete?');")
End Sub

When i run this code, If i click the button first time, it doesn't
work. From the second time onwards the alert is working.

What i have to do, to correct this problem?.

Regards,
Raju.

This is no wrong,the Handle is double click.

you are rendering the javascript on the button only after they click it
once, so it will never work the first time. add it whenever you databind
the grid.
