Upload in radgrid

[Qixiong Zhen]

Dear telerik team
My case is like this:
I have a table, which has column Author, Filename,
The table will be display in rad grid view.
Initially, the table is empty, when user click a button on the grid view, the rad upload control appear. then user can upload the file to a folder in server side and save the file name and author to table in back end.
The grid view will display the input from the table.

I have read some example such as :
  http://demos.telerik.com/aspnet-ajax/controls/examples/integration/raduploadinajaxifiedgrid/defaultcs.aspx?product=upload

What confuse me in the above example is :
1 I can see the control radUpload  in the apsx file;
2 in c# code, 

    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                GridBinaryImageColumnEditor editor =   ((GridEditableItem)e.Item).EditManager.GetColumnEditor("Upload") as GridBinaryImageColumnEditor;
                TableCell cell = (TableCell)editor.RadUploadControl.Parent;
                CustomValidator validator = new CustomValidator();
                validator.ErrorMessage = "Please select file to be uploaded";
                validator.ClientValidationFunction = "validateRadUpload";
                validator.Display = ValidatorDisplay.Dynamic;
                cell.Controls.Add(validator);
            }
        }
How to get the "editor", if column is not a image column.

If you have a good example code, that is much better to help me.

Thanks a lot!

Hello Qixiong Zhen,

Generally, you can use the same approach for all the different editable columns (those that implement the IGridEditableColumn interface). The only difference would be the column editor type. For example the GridBoundColumn, by default provides a GridTextBoxColumnEditor for each cell. Here is how the code looks for this column type:

protected void  RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridTextBoxColumnEditor editor =   ((GridEditableItem)e.Item).EditManager.GetColumnEditor("MyBoundColumn") as GridTextBoxColumnEditor;
    }
}

For more information about the default column editors that the different column types provide, please check the following help article:

I hope this helps,
