Diplay= false does not work

[Mike]

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,

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.

[Mike]

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.

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";
                                }
}
