Telerik.Web.UI.GridDataItemCancelEventArgs OnRowDeselecting Property

Note

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 row deselection.

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

Note that this event cannot be canceled when CTRL key is used to select/deselect rows.

Example:

CopyASPX
<telerik:RadGrid ID="RadGrid1" runat="server">
    <ClientSettings>
        <ClientEvents OnRowDeselecting="RowDeselecting" />
    </ClientSettings>
</telerik:RadGrid>
CopyJavaScript
function RowDeselecting(rowObject) {
    alert("Deselecting row: " + eventArgs.get_itemIndexHierarchical());
}
//OR
function RowDeselecting(rowObject) {
    eventArgs.set_cancel(true) //cancel event;
}
Note

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()
