- Here in the above example, if the user click on Button B1 or Button B2 same task will be performed but we want to perform different task, when user clicks on B1 and B2 Buttons, By calling the same Function for this purpose we use Command Name property but Command Name property not support by click Event and support by CommandEvent so we call the Function F1 from Command Event of both the Button and perform different task
Example to
perform different tasks by calling the same Function from two or more Buttons:
Create a New web page, Design the Webpage
- Select the btnWelcome --- Go to properties window --- Type ‘Wel’ in CommandName property
- Click on Events Button ---Go to Command Event Type “F1” press enter key
- Select the Button btnHellow--- Go to properties window --- Type ‘Hel’ in Command name property
- Go to CommandEvent type the Function name ‘F1’ --- Double Click there
protected void
F1(object sender, CommandEventArgs
e)
{
if
(e.CommandName == "Wel")
txtSample.Text = "Welcome";
else if (e.CommandName == "Hel")
txtSample.Text = "Hellow";
}
