avani  you can do thi without Javascript by Simple Foreach Loop protected void btnCheckAll_Click( object sender EventArgs e) { foreach ( RepeaterItem item in Repeater1.Items) { (( CheckBox )item.FindControl( checkbox1 )).Checked = true ; } } Similarly you can make them uncheck too .. :) make sure that when you bind the Reapeter at Page_Load() you code should be in if ( !IsPostback) { } if my answer helps you then Check Do you like this answer check box :)
