Remove GridExpandColumn in Hierarchy grid

[Sergey]

Hi

I have a grid with 2 tables hierarchy

System autogenerates <telerik:GridExpandColumn> columm. How I can remove it?
When I try to add ExpandCollapseColumn-Visible="false" for MasterTableView - no changes. Other properties works (for example ExpandCollapseColumn-ButtonType="ImageButton")

How I can remove this column?
(I wish to add expanding features to whole row)

When I try to add <telerik:GridExpandColumn></telerik:GridExpandColumn> System generates 2 expand columns

Current test grid is here:

	<telerik:RadGrid ID="rgAttachmentsGrid" AllowPaging="False" runat="server"  Skin="CommonGrid" EnableEmbeddedSkins="false"  BorderStyle="Solid"  GridLines="None" AutoGenerateColumns="false" CellPadding="0" CellSpacing="0"
	OnItemCreated="rgAttachmentsGrid_ItemCreated" OnItemCommand="rgAttachmentsGrid_ItemCommand" >
	<MasterTableView DataKeyNames="AttGroupID" DataMember="Group" AutoGenerateColumns="False" EditMode="InPlace" InsertItemDisplay="Top" CommandItemDisplay="Top"  AllowAutomaticInserts="true"  BorderStyle="None" CellPadding="0" CellSpacing="0"
	ExpandCollapseColumn-Visible="false"    >
	<CommandItemSettings AddNewRecordText="<%$ Language:Translate:str_Field_Editor_AddNewItem %>" RefreshText="<%$ Language:Translate:str_Field_Editor_Refresh %>" />
	<DetailTables>
	<telerik:GridTableView DataKeyNames="AttachID" DataMember="Attachment" AutoGenerateColumns="false">
	<ParentTableRelation>
	<telerik:GridRelationFields DetailKeyField="AttGroupID" MasterKeyField="AttGroupID" />
	</ParentTableRelation>
	<Columns>
	<telerik:GridBoundColumn DataField="FileName" UniqueName="ID1" Visible="True" >
	</telerik:GridBoundColumn>
	</Columns>
	</telerik:GridTableView>
	</DetailTables>
	<Columns>
	<telerik:GridBoundColumn DataField="AttGroupID" UniqueName="ID" Visible="False" >
	</telerik:GridBoundColumn>
	<telerik:GridTemplateColumn>
	<ItemTemplate>
	<asp:LinkButton ID="lbGroup" runat="server" Width="100%"></asp:LinkButton>
	</ItemTemplate>
	</telerik:GridTemplateColumn>
	</Columns>
	</MasterTableView>
	</telerik:RadGrid>

Hi Sergey,

Try the following code snippet to hide the Expand/Collapse column in RadGrid.

CS:

  protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        RadGrid1.MasterTableView.GetColumn("ExpandColumn").Display = false;
    }

Cheers
Shinu.

Hi Shinu, thanks for the answer!
This property helped me (as well as your solution)

ExpandCollapseColumn-Display

="false"

Thanks! This worked for me, too. Here is the VB version.

VB:

Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As EventArgs) _
    Handles RadGrid1.PreRender
    RadGrid1.MasterTableView.GetColumn("ExpandColumn").Display = False
End Sub

Thanks, Matthew
