    <p>Given the following GridView code:</p> <pre><code>&lt;asp:GridView ID="gvReq" runat="server" DataSourceID="objdsReq" &gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText="Control"&gt; &lt;ItemTemplate&gt; &lt;asp:LinkButton ID="lbdelete" runat="server" CommandArgument='&lt;%# Container.DataItemIndex %&gt;' ForeColor="Red" CommandName="DeleteReq"&gt;Delete&lt;/asp:LinkButton&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;asp:ObjectDataSource ID="objdsReq" runat="server" SelectMethod="GetDataTable" &gt; &lt;%-- parameter list --%&gt; &lt;/asp:ObjectDataSource&gt; </code></pre> <p>In the RowDataBound event, JavaScript code is added:</p> <pre><code>Protected Sub gvReq_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvReq.RowDataBound If (e.Row.RowType = DataControlRowType.DataRow) Then Dim lbdelete As LinkButton = e.Row.Cells(DELETE_CELL).Controls.Item(1) lbdelete.Attributes.Add("onclick", "javascript:if(confirm('Are you sure you want to delete?')){return true}else{return false}") </code></pre> <p>The JavaScript fires, but the RowCommand event will never fire - I'm guessing because it is only handled by the JavaScript:</p> <pre><code>Protected Sub gvReq_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvReq.RowCommand Dim dataItemIndex As Integer = Convert.ToInt32(e.CommandArgument) Dim reqID As Integer = Convert.ToInt32(gvReq.DataKeys(dataItemIndex).Values(0)) If e.CommandName = "DeleteReq" Then </code></pre> <p>The JavaScript confirmation dialog was put there by requirement by Management.</p> <p>Now, how do I get the RowCommand Event Handler to fire if someone clicks <code>OK</code> to the JavaScript confirm box? </p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
