    <p>I've got a radio button list inside a grid view like so:</p> <pre><code>&lt;asp:GridView ID="gvLineItems" runat="server"&gt; &lt;asp:TemplateField&gt; &lt;asp:RadioButtonList ToolTip="Please provide an answer to the method." AutoPostBack="true" RepeatDirection="Horizontal" ID="rbAnswer" runat="server" SelectedValue='&lt;%# DataBinder.Eval(Container, "DataItem.AnswerID")%&gt;' OnSelectedIndexChanged="rbAnswer_SelectedIndexChanged"&gt; &lt;asp:ListItem Text="Yes" Value="Yes" style="color:green;"&gt;&lt;/asp:ListItem&gt; &lt;asp:ListItem Text="No" Value="No" style="color:red;"&gt;&lt;/asp:ListItem&gt; &lt;asp:ListItem Text="N/A" Value="N/A" style="color:gray;"&gt;&lt;/asp:ListItem&gt; &lt;asp:ListItem Value="" Text="" style="display: none" /&gt; &lt;/asp:RadioButtonList&gt; &lt;/asp:TemplateField&gt; &lt;/asp:GridView&gt; </code></pre> <p>Currently when you change the selection of the radio button it calls <code>rbAnswer_SelectedIndexChanged()</code> in code behind...</p> <p>The code behind this (and I will shorten it), is something to the effect of:</p> <pre><code> protected void rbAnswer_SelectedIndexChanged(object sender, EventArgs e) { GridViewRow gr = (GridViewRow)((DataControlFieldCell)((RadioButtonList)sender).Parent).Parent; RadioButtonList rbl = (RadioButtonList)gr.FindControl("rbAnswer"); //since the answer changed set some hidden fields as being changed... HtmlInputHidden hiddenFieldAnswered = (HtmlInputHidden)gr.FindControl("hdnAnswered"); hiddenFieldAnswered.Value = "1"; HtmlInputHidden hiddenField = (HtmlInputHidden)gr.FindControl("hdnIsChanged"); hiddenField.Value = "1"; Panel p; p = (Panel)gr.FindControl("pnlAnswer"); switch (rbl.SelectedItem.Text) { case "No": gr.Cells[0].BackColor = System.Drawing.Color.Red; p.Visible = true; break; case "Yes": gr.Cells[0].BackColor = System.Drawing.Color.Green; p.Visible = false; break; case "N/A": gr.Cells[0].BackColor = System.Drawing.Color.Gray; p.Visible = false; break; default: gr.Cells[0].BackColor = System.Drawing.Color.Transparent; p.Visible = false; break; } } </code></pre> <p>Basically if you select an answer it changes the color of a cell in the gridview and it either hides or unhides a panel. Doing this as back end code causes a big delay in the application. Can I do this in jquery? If so how do I access the radiobuttonlist, the answer, the panel, and a way to change the color of the first cell (<code>gr.cells[0].backcolor</code>) in jquery?</p> <p>If I do this all on the client side it may increase the usability for the end users, they are complaining right now it is too slow.</p>

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.
