I have a grid that uses a form template for editing the grid items.  When the user clicks the edit command for a row in the grid it opens the FormTemplate that contains a FileExplorer.  I need to then set the configuration path of the file explorer as it's different for each item in the grid.

It seems the FileExplorer paths can only be set on the page_load event, but at that time I don't have access to the GridEditFormItem that allows me to get the file explorer control and set the paths.

Is there a way to make this work?  It seems pretty strange that the view paths can only be set in the page_event.

Thanks

Hello Spencer,

You can use the ItemCreated or ItemDataBound event handler to achieve this requirement. Please check the following section for a viable approach appropriate for tour chosen EditMode:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-editinsert-mode

Hope this helps.

This doesn't work because the view path of the file explorer control needs to be set on the page_load event.

Hi Spencer,

Have you tried both in ItemCreated and ItemDataBound? Alternatively, you can use the own event handlers of the control - Init, Load, PreRender:
protected void RadFileExplorer1_PreRender(object sender, EventArgs e)
{
    RadFileExplorer explorer = (RadFileExplorer)sender;
    GridDataItem item = (GridDataItem)explorer.NamingContainer;
    string value = item.GetDataKeyValue("OrderID").ToString();
}
