    I have a Radgrid and have several columns set to Display=False and when a user sorts or expands on a column the hidden columns appear and I even set the itemstyle-width to 0.

     

    <telerik:RadGrid ID="RadGrid1" 

    AllowMultiRowSelection="True" 

    AllowSorting="True"

    AllowNaturalSort="True"  

    AllowPaging="True"
    AlternatingItemStyle-HorizontalAlign="Center" 

    AutoGenerateColumns="false"  

    BackColor="#ffffff" 

    CellPadding="2"  

    CellSpacing="2" 

    GridLines="None"  

    GroupingEnabled="True" 

    HeaderStyle-Height="20"  

    Height="580px" 

    OnNeedDataSource="RadGrid1_NeedDataSource"  

    OnItemDataBound="RadGrid1_ItemDataBound" 

    OnSortCommand="RadGrid1_SortCommand"  

    OnExcelExportCellFormatting="RadGrid1_ExcelExportCellFormatting" 

    SelectedItemStyle-ForeColor="#000000"  

    PageSize="15" 

    ShowFooter="True"  

    ShowHeader="True" 

    ShowGroupPanel="True"  

    ShowStatusBar="True" 

    EnableEmbeddedSkins="False"  

    Skin="Nuts" 

    Width="100%"  

    Visible="true" 

    runat="server">  
    -- Now for the columns

    <telerik:GridBoundColumn DataField="status_id" ItemStyle-Width="0" Display="False" />

    <telerik:GridBoundColumn DataField="request_id" ItemStyle-Width="0" Display="False" />  

    <telerik:GridBoundColumn DataField="refresh_time" ItemStyle-Width="0" Display="False" /> 

    <telerik:GridBoundColumn DataField="number_of_days" ItemStyle-Width="0" Display="False" />  

    <telerik:GridBoundColumn DataField="request_number" UniqueName="RequestNumber" ItemStyle-Width="0" Display="False" />

    <ClientSettings AllowDragToGroup="True" EnablePostBackOnRowClick="False">

            <Resizing AllowColumnResize="True" AllowRowResize="False" ResizeGridOnColumnResize="False" ClipCellContentOnResize="True" EnableRealTimeResize="False" />
             <Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" FrozenColumnsCount="3" />
             <Selecting AllowRowSelect="True" />
    </ClientSettings>

    Any help would be appreciated and I have attached an image.

    Hi Mike,

    I have tried to replicate your issue but no avail.I see that you have set all the bound columns visibility to false. I couldn't replicate with that code.Here is the code i tried with some column made visible. Please let know if any concern .

    ASPX:
    <telerik:RadGrid ID="RadGrid1" AllowMultiRowSelection="True" AllowSorting="True"
        AllowNaturalSort="True" AllowPaging="True" AlternatingItemStyle-HorizontalAlign="Center"
        AutoGenerateColumns="false" BackColor="#ffffff" CellPadding="2" CellSpacing="2"
        GridLines="None" GroupingEnabled="True" HeaderStyle-Height="20" Height="580px"
        SelectedItemStyle-ForeColor="#000000" PageSize="15" ShowFooter="True" ShowHeader="True"    ShowGroupPanel="True" ShowStatusBar="True" Width="100%" Visible="true" runat="server">
        <MasterTableView>
            <Columns>
                <telerik:GridBoundColumn DataField="OrderID" HeaderText="OrderID" />
                <telerik:GridBoundColumn DataField="ShipVia" HeaderText="ShipVia" />
                <telerik:GridBoundColumn DataField="EmployeeID" Display="false" />
                <telerik:GridBoundColumn DataField="ShipCity" ItemStyle-Width="0" Display="False" />
                <telerik:GridBoundColumn DataField="CustomerID" ItemStyle-Width="0" Display="False" />
            </Columns>
        </MasterTableView>
        <ClientSettings AllowDragToGroup="True" EnablePostBackOnRowClick="False">
            <Resizing AllowColumnResize="True" AllowRowResize="False" ResizeGridOnColumnResize="False"
                ClipCellContentOnResize="True" EnableRealTimeResize="False" />
            <Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" FrozenColumnsCount="2" />
            <Selecting AllowRowSelect="True" />
        </ClientSettings>
    </telerik:RadGrid>

    Thanks,
    Princy

    Prciny,

    Thank you for the quick response.

    I am not using visible=false because if I do the values are not passed in EventArgs.  The only way to pass them and keep them hidden without using datakeys is to use Display=false.

    It seems like any grouping or resizing in the ClientSettings is causing the display=false columns to reappear.

    Hello Mike,

    Please note that having hidden columns (with Display property set to false) or hiding/showing columns and frozen columns are not supported at the same time as stated in the following topic:
    http://www.telerik.com/help/aspnet-ajax/grid-frozen-columns.html

    I hope the clarification was helpful.

    Regards,
    Eyup

    Hi Mike, yesterday i got same issue. After doing some investigation i found that when we set any columns to display=false, its apply apply a style on that column i.e. style ="Display:none". When we did some update on grid than that style is like  style =" " thats why these hidden column visible. To solve this issue i assigned css class to these column which had display=false. Sample code is given below in my case i created custom control using RadGrid.
     <style type="text/css">

      .ItemStyle {
        display:none;
            }
        </style>
     protected void RadGrid1_PreRender(object sender, EventArgs e)
            {
                GridBoundColumn boundColumn = Column as GridBoundColumn;
                                 
                                    boundColumn.Display = Convert.ToBoolean(Convert.ToInt32(GridSchema.ColumnVisibleSplit[i].ToString()));
                                    if (!boundColumn.Display)
                                    {
                                        boundColumn.HeaderStyle.CssClass = "ItemStyle";
                                        boundColumn.ItemStyle.CssClass = "ItemStyle";
                                        boundColumn.FooterStyle.CssClass = "ItemStyle";
                                    }
    }
