GridDropDownColumn AutoPostback on SelectedIndex Change

[Steve]

I have a RadGrid that is setup to use the InLine edit mode.  He is snippet of code containing the GridDropDownColumn.

<telerik:GridDropDownColumn DataField="BreakTypCd" ListDataMember="BreakTyp"
                            HeaderText="Break Type" ListTextField="Descript" ListValueField="BreakTypCd"
                            UniqueName="BreakTyp" ColumnEditorID="GridDropDownColumnEditor1">
</telerik:GridDropDownColumn>

When I enter Edit mode, I would like a SelectedIndex event fired.  This will allow me to update other item on the row.  I don't see any events in the GridDropDownColumn properties list.

Any thoughts on how I get an event to fire?

Thanks.

Hi,

You can access the Dropdownlist of the GridDropdownColumn in the edit mode in the ItemCreated event  and  attach the SelectedIndexChanged event as shown below:

C#

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                DropDownList list = (e.Item as GridEditableItem)["DropDownColumn1"].Controls[0] as DropDownList;

                //attach SelectedIndexChanged event for the dropdown control
                list.AutoPostBack = true;
                list.SelectedIndexChanged += new EventHandler(list_SelectedIndexChanged);
            }
        }

        void list_SelectedIndexChanged(object sender, EventArgs e)
        {
            //first reference the edited grid item through the NamingContainer                                                     attribute
            GridEditableItem editedItem = (sender as DropDownList).NamingContainer as GridEditableItem;



        }

Hope this helps.

Thanks,
