ReadOnly column in Edit Form?

[Rick]

In the following extracted code, column 'Id' is not visible at all times.  Column 'AE' should be invisible, too.  However, column 'AE' appears in the EditForm despite event ItemDataBound event which sets both columns Visible = False.

How can I hide column AE?


<telerik:RadGrid ID="rgHeader" runat="server" CellSpacing="0" DataSourceID="sdsHeader">

<MasterTableView AutoGenerateColumns="False" CommandItemDisplay="Top" DataSourceID="sdsHeader">

<CommandItemSettings ExportToPdfText="Export to PDF" AddNewRecordImageUrl="Images/new.png" AddNewRecordText="Add Header"></CommandItemSettings>

<Columns>

<telerik:GridButtonColumn Text="Select" CommandName="Select" UniqueName="Select" ItemStyle-Width="30px"></telerik:GridButtonColumn>

<telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>

<telerik:GridBoundColumn DataField="AE" HeaderText="AE" SortExpression="AE" UniqueName="AE"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Total" DataType="System.Int32" HeaderText="Total"

SortExpression="Total" UniqueName="Total">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Id" DataType="System.Int32" HeaderText="Id" ReadOnly="True"

SortExpression="Id" UniqueName="Id">

</telerik:GridBoundColumn>

</Columns>

<EditFormSettings>

<EditColumn UniqueName="EditCommandColumn1" FilterControlAltText="Filter EditCommandColumn1 column"></EditColumn>

</EditFormSettings>

</MasterTableView>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

</telerik:RadGrid>

Protected Sub rgHeader_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles rgHeader.ItemDataBound

  rgHeader.MasterTableView.GetColumn(

"Id").Visible = False

  rgHeader.MasterTableView.GetColumn(

"AE").Visible = False

 

End Sub

If I can't hide column 'AE', my requirements would allow Visible=True, but in a ReadOnly state, e.g. Label instead of Textbox control.

How might I do this?

hi,

there are two way to achieve this.
Solution 1 :

<telerik:GridBoundColumn DataField="ID" HeaderText="ID" UniqueName="ID"></telerik:GridBoundColumn>

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridEditFormItem && e.Item.IsInEditMode && !e.Item.OwnerTableView.IsItemInserted)
            //if the item is about to edit
            {
                GridEditFormItem edititem = (GridEditFormItem)e.Item;
                TextBox txtboxID = edititem["ID"].Controls[0] as TextBox;
                txtboxID.ReadOnly = true;
            }
        }

 
Solution 2:

<telerik:GridTemplateColumn DataField="ID" HeaderText="ID" UniqueName="ID">
                        <ItemTemplate>
                            <%# Eval("ID") %>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:Label ID="lblIDEdit" runat="server" Text='<%# Eval("ID") %>'></asp:Label>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

Thanks,

Thanks Jayesh!

These suggestions work well.
