Given In the screen shoot, when I selected the highlighted row, the value of 'Michigan' was replaced with the last value that I selected which is 'Arizona' from the previous row.  Also notice that "Albuquerque', 'Arizona', 'Boise' and the row under 'Cascades' are either selected or the background is grayed. They were also selected for rows towards the top of the grid.

Below is the code used in the markup and the codebehind

<ig:RowEditingClientBinding ColumnKey="Territory" ControlID="control_Territory"             GetValueJavaScript="$find({ClientID}).get_selectedItem().get_value()"            SetValueJavaScript="$find({ClientID}).set_currentValue({value},true)" />

<div class="lbl">&nbsp;Territory:&nbsp;</div>
   <ig:WebDropDown ID="control_Territory" DisplayMode="DropDownList" DataSourceID="SqlDataSource2"
      TextField="mktgrpname" ValueField="mktgrpname" runat="server" Width="250px"
      EnableDropDownAsChild="true" ClientEvents-Initialize="setZIndex"  DropDownOrientation="Default"
      DropDownItemBinding-TextField="mktgrpname" DropDownItemBinding-ValueField="mktgrpname">
   </ig:WebDropDown>
</div>

Protected Sub GridView_RowSelectionChanged(ByVal sender As Object, ByVal e As Infragistics.Web.UI.GridControls.SelectedRowEventArgs) Handles GridView.RowSelectionChanged

        Dim DDLB As WebDropDown = _
            TryCast(GridView.Behaviors.EditingCore.Behaviors.RowEditTemplate.TemplateContainer.FindControl("control_Territory"), WebDropDown)
        If Not IsNothing(DDLB) Then
            If e.CurrentSelectedRows.Count > 0 Then
                DDLB.ClearSelection()
                DDLB.SelectedItemIndex = -1
                DDLB.DataBind()
                DDLB.CurrentValue = e.CurrentSelectedRows.Item(0).Items(14).Value
                DDLB.SelectedValue = e.CurrentSelectedRows.Item(0).Items(14).Value
            End If
        End If

    End Sub

What do I need to do to have all previously selected entries deselected (not highlighted and the background white) and highlight the currently selected rows entry highlighted?

Thanks in advance.

just like in http://samples.infragistics.com/2010.2/WebFeatureBrowser/Default.aspx

Hello Ram,

A simpler way would be to call a function from the DropDownList in the RowEditTemplate after the user selects a new value. 

The following code demonstrates how to use a DropDownList to call a function in the WebDataGrid RowEditTemplate in place of the WebDropDown:

Replace the RowEditingClientBinding for the WebDropDown with the code for the DropDownList as shown here:
<ig:RowEditingClientBinding ColumnKey="ShipperID" ControlID="control_Shipper"
         GetValueJavaScript="getSelectedText({ClientID})" />

Add this function to the page:
         function getSelectedText(clientID) {
                 var dropDown = document.getElementById(clientID);
                 var selectedText = dropDown.item(dropDown.selectedIndex).text;
                 return selectedText;
         }

The above code will return the newly selected value in the DropDownList to the WebDropDown.

Please let me know if this information is helpful.
Thank you.
