Binding RadCombo Box in a RadGrid

[pbarron]

I trying to bind and assign a selected value to a rad combo box in rad grad

This is in  popup edit mode.  the combo box is referencing another table, and I wish to bind this progmatically.

I am calling 'OnItemsRequested' which binds the dropdown on request but I need it to bind and select the selected value when form is displayed.

<EditFormSettings CaptionFormatString="Group form" EditFormType="Template" EditColumn-CancelImageUrl="../img/grid/Cancel.gif"
                CaptionDataField="GroupName">
                <FormStyle BackColor="#eef1ba" BorderColor="#3b3b3a" BorderWidth="1" BorderStyle="Solid" />
                <FormTemplate>
                    <div class="Editform">
                        <!-- Business unit -->
                        <div id="group">
                            <label>
                                <asp:Label ID="lblGroup" runat="server" Text="Group name: "></asp:Label></label>

            </EditFormSettings>

    protected void rcbBuisinessUnit_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
    {
        Data.vaccineprofessionalDataContext db = new Data.vaccineprofessionalDataContext();
        var results = db.vpBusinessUnitSeach("", "UnArchive");
        RadComboBox comboBox = (RadComboBox)sender;
        comboBox.DataSource = results;
        comboBox.DataBind();
    }

 
Any suggestion would be great.

Thanks

Hello pbarron,

You can get the item through the editForm's dataItem, as shown in the code snippet below:

.cs

if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
        {
            GridEditFormItem editForm = (GridEditFormItem)e.Item;
            DataRowView dataItem = (DataRowView)editForm.DataItem;
            Response.Write(dataItem["CustomerID"]);
        }

I hope this information helps.

Best wishes,
Yavor
