Dear All!

I have a RadGrid. In it I have more different dropdown type columns. I want to do to bind them to different datasources in Edit state.
I have custom collections: List<One>,List<Two>,List<Three>

Can I bind them to dropdowns one-by-one in design time? like here:
<
telerik:GridDropDownColumn DataField="OrderID" ListTextField="ShipCountry" ListValueField="OrderID"  DataSourceID="SqlDataSource4" HeaderText="GridDropDownColumn <br /> with RadComboBox" DropDownControlType="RadComboBox" /> - just with my custom Collections.


How can I bind collections to dropdowns?

thanks
alsi

thanks but this is not what I really want.
I want to know if I have two datasource eg.: AccessDataSource and a different List<T>, how can I bind it to the same grid means:
AccessDataSource bind to the grid and almost all Column get data from it, except one which is a DropDown which need to use the List<T> datasource but a grid's column (inside the same grid)

thx

Hello Alsi,

You can bind the dropdowncolumn when in EditMode as shown in the code below:
aspx:
<telerik:GridDropDownColumn UniqueName="DropDownColumn" DataField="OrderID" ListTextField="ShipCountry" ListValueField="OrderID" DataSourceID="SqlDataSource4" HeaderText="GridDropDownColumn <br /> with RadComboBox" DropDownControlType="RadComboBox" > 
</telerik:GridDropDownColumn> 
 
          

cs:
 
 private void RadGrid1_ItemDataBound(object  sender, Telerik.Web.UI.GridItemEventArgs e)  
{  
   if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode )  
   {  
        GridEditableItem editedItem = e.Item as GridEditableItem;  
        GridEditManager editMan = editedItem.EditManager;  
  
        GridDropDownListColumnEditor editor = editMan.GetColumnEditor( "DropDownColumn" ) as GridDropDownListColumnEditor;  
               //Then you can modify the list control as per your custom conventions  
        editor.DataSource = List<T>;  
        editor.DataBind();         
   }  
}
