Removing columns in Download List template

Posted by Community Admin on 27-Aug-2013 00:00

I have modified the default download list template to have custom fields that I am using in association with the document manager.

I am now trying to remove the documentType and totalSize columns of the template.

When I comment them out, I get a server error:
Cannot find a cell bound to column name 'documentType'

Here is my code:

<%@ Control Language="C#" %>

<%@ Register TagPrefix="telerik" Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" %>

<%@ Register TagPrefix="sitefinity" Namespace="Telerik.Sitefinity.Web.UI" Assembly="Telerik.Sitefinity" %>

<%@ Register TagPrefix="sf" Namespace="Telerik.Sitefinity.Web.UI.PublicControls.BrowseAndEdit" Assembly="Telerik.Sitefinity" %>

<sitefinity:ResourceLinks id="resourcesLinks2" runat="server" UseEmbeddedThemes="true" Theme="Default">

<sitefinity:ResourceFile Name="Telerik.Sitefinity.Resources.Themes.Basic.Styles.icons.css" Static="true" />

</sitefinity:ResourceLinks>

<sf:BrowseAndEditToolbar ID="browseAndEditToolbar" runat="server" Mode="Edit"></sf:BrowseAndEditToolbar>

<telerik:RadGrid id="documentsGrid" runat="server"

CssClass="sfdownloadTable sfTableMode"

skin="Sitefinity">

<ClientSettings EnableRowHoverStyle="true" EnableAlternatingItems="true" />

<PagerStyle Mode="NumericPages" />

<MasterTableView PageSize="50" EnableNoRecordsTemplate="true">

<Columns>

<telerik:GridBoundColumn UniqueName="title"

HeaderText="<%$ Resources:Labels, File %>" DataField="Title" ItemStyle-CssClass="sfdownloadTitle" HeaderStyle-CssClass="sfdownloadTitle" />

<%-- <telerik:GridBoundColumn UniqueName="documentType"

HeaderText="<%$ Resources:Labels, Type %>" DataField="Extension" ItemStyle-CssClass="sfdownloadType" HeaderStyle-CssClass="sfdownloadType" /> --%>

<telerik:GridBoundColumn UniqueName="totalSize"

HeaderText="<%$ Resources:Labels, Size %>" DataField="TotalSize" ItemStyle-CssClass="sfdownloadSize" HeaderStyle-CssClass="sfdownloadSize" />

<telerik:GridBoundColumn UniqueName="uploadedOn"

HeaderText="<%$ Resources:Labels, UploadedOn %>" DataField="DateCreated" DataFormatString="0:dd MMM, yyyy" ItemStyle-CssClass="sfdownloadDate" HeaderStyle-CssClass="sfdownloadDate" />

<%-- Custom Column --%>

<telerik:GridTemplateColumn

UniqueName="actionColumn"

HeaderText="Download/Link"

ItemStyle-CssClass="sfdownloadCell" HeaderStyle-CssClass="sfdownloadCell">

<ItemTemplate>

<a href="<%# (Eval("

FormURL") ==  null ) ? Eval("MediaUrl") : Eval("FormURL") %>" ><%# (Eval("FormURL") ==  null ) ? "Download" : "Access Smart Form" %></

a>

</ItemTemplate>

</telerik:GridTemplateColumn>

<%-- Custom Column --%>

<telerik:GridTemplateColumn

UniqueName="deptartmentColumn"

HeaderText="Department"

ItemStyle-CssClass="sfdownloadCell" HeaderStyle-CssClass="sfdownloadCell">

<ItemTemplate>

<%# Eval("Department") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<NoRecordsTemplate>No documents found!</NoRecordsTemplate>

</MasterTableView>

</telerik:RadGrid>

<sitefinity:Pager id="pager" runat="server"></sitefinity:Pager>

Please advise. Thank you.

Hello Tyler,

Removing the columns from the template would result in error since the code of the widget searches for those columns. The easiest and fastest way to hide the unwanted columns is to set their Visibility to false.

<telerik:GridBoundColumn Visible="false" UniqueName="documentType"

HeaderText="<%$ Resources:Labels, Type %>" DataField="Extension" ItemStyle-CssClass="sfdownloadType" HeaderStyle-CssClass="sfdownloadType" />

I hope this helps.
