Where to set AllowedFileExtensions property for RadUpload in RadGrid

[Bernard]

Hi,

I have a RadUpload in a RadGrid. I would like set the AllowedFileExtensions property at the code-behind rather through the aspx page itself. In which event should I set this? I've tried it in the '... Insert' event, but it seems that the code does not detect it and allowed the invalid files to go through.

Thanks,
Bernard

Hello Bernard,

You would set it in the ItemCreated event. It would look something like this:

if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
     GridEditableItem editItem = (GridEditableItem)e.item;
     GridTemplateColumnEditor uploadEditor = (GridTemplateColumnEditor)editItem.EditManager.GetColumnEditor("columnUniqueName");

      .....additional code to pull upload control.....
}

What the code does above is check that the grid in edit mode (raised during insert/update) and that the item is a GridEditableItem (that is the item you'll need in order to access the controls). Now depending on the column type you're using, I'm assuming it's a GridTemplateColumn, but if it's another type you'll need to change the conversion to that column editor type.

From there you'll do a FindControl to pull out your RadUpload control and then set the AllowedFileExtensions property.

I hope that helps.

Hi Bernard,

You may also use the ItemDataBound event. Please consult with the attached project.
