Question

I’ve got a asp:TextBox that is populated from a javascript function, but when this happens the server side TextChanged event is not fired, only when I change the text with my keyboard.

Is there a solution for this? Why is client/server integration so painful in asp.net?

(AutoPostBack is set to true)

Thank you

Answer 1

Way 1:

function DoPostBack()
{
   __doPostBack("txt_sssn_dt", "TextChanged");
}

Calling ASP.NET server-side events using JavaScript

Way 2:

Calling Server Side function from Client Side Script

Way 3:

one of the way to set focus lost like this

function texboxchange() {
        var txtBox = document.getElementById('<%= TextBox4.ClientID %>');
        var count = txtBox.value.length;
        if (count == 2) 
        {
           document.getElementById('<%= TextBox12.ClientID %>').focus();
           return true; // this will call textbox changed event.
        }
    }
