How to fire a javascript on change of Page size drop down.

[kalyan gupta]

Hi @

I am using Telerik Rad Grid in one of my applications.

Now When ever I change the page size of Telerik RadGrid or when ever i click on Pagination. I need to call a javascript function.

I tried to find the page size Rad combo which is used inside Grid and attaching an event which would call a javascript. But It was not working.

Please let me know how to achieve this.

Thanks in advance.

Hi kalyan gupta,

You can use the following approach:

C#

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridPagerItem)
    {
        RadComboBox c = e.Item.FindControl("PageSizeComboBox") as RadComboBox;
        c.OnClientSelectedIndexChanged = "handlerName";
    }
}

Javascript

function handlerName(sender, args)
{
    // put your code here
    // ........
    alert("OnClientSelectedIndexChanged");

    // execute the default handler afterwards, which change the page size
    Telerik.Web.UI.Grid.ChangePageSizeComboHandler(sender, args);
}
