Problem with a button's OnClientClick event inside an UpdatePanel
- by royals
im using javascript like
var TargetBaseControl = null;
window.onload = function()
{
try
{
//get target base control.
TargetBaseControl =
document.getElementById('<%= this.GridView1.ClientID %>');
}
catch(err)
{
TargetBaseControl = null;
}
}
function TestCheckBox()
{
if(TargetBaseControl == null) return false;
//get target child control.
var TargetChildControl = "chkSelect";
//get all the control of the type INPUT in the base control.
var Inputs = TargetBaseControl.getElementsByTagName("input");
for(var n = 0; n < Inputs.length; ++n)
if(Inputs[n].type == 'checkbox' &&
Inputs[n].id.indexOf(TargetChildControl,0) >= 0 &&
Inputs[n].checked)
return true;
alert('Select at least one checkbox!');
return false;
}
and inside the update panel i have code like
<asp:Button ID="ButtonSave" runat="server" OnClick="ButtonSave_Click"
OnClientClick="javascript:return TestCheckBox();" Text="Save" />
when i run the page and click the button then no more further processing just button has been click nothing happan......
