[Solved] How to access RadUpload control in a grid for server side validation

[FreshOne]

hi all,
i have a RadUpload control in a RadGrid. i added a CustomValidator, i'm validating file extensions in a javascript function, and i need to validate the file size in a server side function bcoz this can't be validated on client side except if i had a RadProgressArea, which i don't (like this example http://www.telerik.com/help/aspnet-ajax/upload_howtoclientfilesize.html).

so i need to add "OnServerValidate" function to the CustomValidator, the problem is how can i access the RadUpload control in this function??

am i in the correct way, or the whole approach is not applicable? how can i do it?

thnx in advance

Hi,

Try the code snippet below  to access a  RadUpload control  in the "OnServerValidate" function of the CustomValidator.You can use the GridEditableItem if you want to access it in the edit mode or the GridDataItem if in normal mode.

C#

 protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
    {
        GridEditableItem editedItem = (GridEditableItem)(source as RadUpload).NamingContainer;
        RadUpload rdUpload = (RadUpload)editedItem["ColumnUniqueName"].FindControl("RadUpload1");

    }

Thanks,

Hi,

Please try the code snippet instead as  shown below to access the RadUpload control on edit and insert:

C#

   protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
        {

            if (RadGrid1.MasterTableView.IsItemInserted != false)
            {
                GridEditFormInsertItem insertItem = (GridEditFormInsertItem)(source as CustomValidator).NamingContainer;
                RadUpload rdUpload = (RadUpload)insertItem["ColumnUniqueName"].FindControl("RadUpload1");
            }
            else
            {
                GridEditableItem editedItem = (GridEditableItem)(source as CustomValidator).NamingContainer;
                RadUpload rdUpload = (RadUpload)editedItem["ColumnUniqueName"].FindControl("RadUpload1");
            }



        }

Thanks,
