In my page i have to add rows dynamically and remove rows dynamically. I have one checkbox and one text boxe for each row which is added dynamically.

Adding and deleting rows works fine. I have problem after deleting. This is due to unchange of id value for checkbox and textboxes.

I assigned the id value in array and incremented while adding and decremented while removing. But the the id and values of the textboxes is not exact. How to fix this?

Solution 1

'ctl00_TextBoxCol_0' this is clientID you can handle control through clientId in javascript.

Instead use

TextBox txtBox = (TextBox)Page.FindControl("TextBoxCol_0");

Why you want clientID? You want to find textbox in javascript or in code behind?

Hi,

Even you can fix your ClientID. Check this link[^]

And for finding any asp.net control through javascript use

JavaScript

var txtdate1 = document.getElementById('<%=txtdate1.ClientID%>');

Hope this will help you,

Thanks
-Amit.
