Telerik.Web.UI.GridDataItemCancelEventArgs OnRowResizing Property


To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel or set_cancel.

This event is fired before a row is resized.

Fired by RadGrid
Arguments id - id of the RadGrid item that has raised the event itemIndexHierarchical - hierarchical index of the item that has raised the event gridDataItem - the corresponding data item tableView - owner TableView of the item that has raised the event dataKeyValues - data key value for the item that has raised the event domEvent - dom event that was raised for the current event
Can be canceled Yes, set eventArgs.set_cancel(true) to cancel


<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server">
        <Resizing AllowRowResize="true" />
        <ClientEvents OnRowResizing="RowResizing" />
function RowResizing(sender, eventArgs) {
    alert("Resizing row instance: " + eventArgs.get_itemIndexHierarchical());
function RowResizing(sender, eventArgs) {
    eventArgs.set_cancel(true) //cancel event

get_gridDataItem() is not directly available on the client unless OnRowCreating/OnRowCreated events are hooked up. This is done for optimization purpose. If you need the rowIndex, you can use eventArgs.get_itemIndexHierarchical()
