In
this post, I will explain how to select and deselect all checkbox in ASP.Net repeater control using JQuery.
When user will select the checkbox in header row then all checkbox from item row is set to select status and vice versa. Also when user will deselect one of the checkbox from item row then header row checkbox will be set to deselect status.
In below example, the first column consists of an ASP.Net checkbox. A checkbox present in the TH element will be used to select and deselect all checkbox in the TR element of ASP.Net Repeater control.
HTML
Code :
<%@
Page Language="VB" AutoEventWireup="false"

table th
{
