Excel-like filter OnClientItemCheckedHandler

[Jas]

Hi,

I would like to call a JavaScript function whenever an item is checked/unchecked in the excel-like filter list.

Please assist with an example of how this could be achieved.

Thank you,

Jas

Hi Jas,

You can achieve this requirement using the following approach:

protected void RadGrid1_FilterCheckListItemsRequested(object sender, GridFilterCheckListItemsRequestedEventArgs e)
{
    e.ListBox.DataBind();

    foreach (RadListBoxItem item in e.ListBox.Items)
    {
        item.Attributes.Add("onclick", "filterListBoxItemClicked(this,event);");
    }
}

JavaScript:

function filterListBoxItemClicked(el, event) {
    if (event.target && event.target.type == "checkbox" && event.target.checked) {
        alert($(el).text());
    }
}

I hope this will prove helpful.

Regards,
Eyup
