If you just double click it in design view it will automatically add a method called void TextBox1_TextChanged()

That's the function that you should edit~



(Note that if you want to do it yourself, you can)
this.textBox1.TextChanged += new System.EventHandler(myEventHandler);


Then, your event handler function should look like this:

void myEventHandler(object sender, EventArgs e) {
    // do stuff here
}

Hope this helps

I don't think that is what you want to do. since you said "server side function", I will assume this is in ASP.Net(you probably should have posted this in the ASP.Net forum). calling a server side function will cause you to do a postback. doing a postback on every keypress is HIGHLY inefficient.

you will want to use javascript.

Didn't see that bit
