DropDownColumn in RadGrid

[Vinita]

Hi,

 

I have created an inline editable grid and has added a dropdowncolumn to the grid. When i am trying to add empty rows to the grid, all other columns are coming as empty but the dropdown column is getting pouplated with the first value in dropdown. I want that column to be empty.
While editing the row how to make the dropdown to display the selected value as the column value.
If have assigned same xml datasource to dropdown columns will it cause any problem?
And I am not able to bind one of my dropdown columns in the grid.

It is throwing the exception: 
System.Web.HttpException: DataBinding: 'System.String' does not contain a property with the name 'ows_InvoiceStatus'.

Thanks in advance,
Vinita

Hello Vinita,

Inorder to display an empty value in the dropdowncontrol for a GridDropDownColumn, you can try adding the following code:
cs:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
      if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            DropDownList ddl = (DropDownList)editItem["DropDown"].Controls[0];
            ddl.AppendDataBoundItems = true;
            ddl.Items.Insert(0,"");
        }
     }

Thanks
Princy.
