After Updating the informations then you can add this code below to Clear all CheckBoxes..

protected void Button1_Click(object sender, System.EventArgs e)

//Codes for Update goes Here 

foreach (Control c in this.Controls)
            if (c.GetType().ToString() == "System.Web.UI.WebControls.TextBox")
                TextBox tb = (TextBox) c;
                if (tb != null)
                      tb.Text = "";

Well, as it is right now. It does work as in, when I step through my code, it does work, however, on the client side, the controls are not cleared at all. That happens to be the problem. Now, when I add the code, however after my AddTransaction Process, I get an Exception since, for some reason, the code executes twice ( I mean all the code within the Button_click event), so on the second run, I get an exception since the textboxes have then been cleared out.

validate Textbox in Web User Control from web form?

So how would I associate a validation control on my web form with the text box inside my web user control?  Can this be done; any alternatives out there?

problems with web control textbox posting back
hi,  i have a simple form with a couple of vb/ web server side textbox controls. They are set to not auto postback  when the text changes ( but they do seem to auto postback when a return key is entered which is fine for me ).   If i hit the return key when focused in these text boxes they cause a postback event but I cannot capture it  server side. I get redirected back to my default web page . If i use an ordinary HTML input box - the same thing  happens.  If I use an ordinary submit html button control everything works fine.  My question...

Textbox value in user control is cleared when back button is pressed
