How do I get a value of a column in the current row if it's not selected? My grid shows data in some bound columns and a template column. The template column has (among other things) a button which will pass a value from that row to open another page via querystring. This doesn't seem like it should be difficult.

Grid only:

<telerik:RadGrid ID="Project_RadGrid" runat="server" CellSpacing="0" DataSourceID="Project_SqlDataSource"

GridLines="None" AllowSorting="True" ShowGroupPanel="True" AllowPaging="True" Skin="Black">

<ClientSettings AllowDragToGroup="True">

<Selecting AllowRowSelect="True" />

</ClientSettings>

<MasterTableView AutoGenerateColumns="False" DataKeyNames="JobNumber" DataSourceID="ProjectSqlDataSource">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column" />

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column" />

<Columns>

<telerik:GridBoundColumn DataField="JobNumber" DataType="System.Decimal" FilterControlAltText="Filter JobNumber column"

HeaderText="JobNumber" ReadOnly="True" SortExpression="JobNumber" UniqueName="JobNumber" Display="False">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="SegmentName" FilterControlAltText="Filter SegmentName column"

HeaderText="Business Segment" SortExpression="SegmentName" UniqueName="SegmentName">

<ItemStyle HorizontalAlign="Left" VerticalAlign="Top" />

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn1 column" HeaderText="Overview"

UniqueName="TemplateColumn1">

<ItemTemplate>

<div>

<table style="width:99%; vertical-align:text-top;">

<tr><th style="width:80%;">

<span style="color:#009900;background-color:#F2F2F2;font-variant:small-caps;"><%# DataBinder.Eval(Container.DataItem, "Overview")%></span>

</th></tr>

<%--

*** Add the summary and integration rows only if there is data.

--%>

<%# If((DataBinder.Eval(Container.DataItem, "Summary") & "") = "", "", "<tr><td>" & DataBinder.Eval(Container.DataItem, "Summary") & "</td></tr>")%>

<%# If((DataBinder.Eval(Container.DataItem, "Integration") & "") = "", "", "<tr><td>" & DataBinder.Eval(Container.DataItem, "Integration") & "</td></tr>")%>

<tr><td>

<asp:Button ID="ShotDetail_Button" runat="server" Text="Shot List..." UseSubmitBehavior="False"

OnClick="ShotDetail_Button_Click" />

<input id="Comments_Button" type="button" value="Comments..." onclick=" $('#div_Comments').toggle();" />

<asp:Button ID="LinkedProjects_Button" runat="server" Text="Linked Projects..." UseSubmitBehavior="False" />

</td></tr>

</table>

</div>

</ItemTemplate>

<ItemStyle HorizontalAlign="Left" VerticalAlign="Top" />

</telerik:GridTemplateColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column" />

</EditFormSettings>

<ItemStyle HorizontalAlign="Left" VerticalAlign="Top" />

</MasterTableView>

<FilterMenu EnableImageSprites="False" />

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default" />

</telerik:RadGrid>

Code behind:

protected void ShotDetail_Button_Click(object sender, System.EventArgs e)

{

//I need JobNumber here

Response.Redirect(string.Format("~/ShotDetail.aspx?JobNo={0}", JobNumber));

}
