    <p>I've been trying to follow this answer: <a href="https://stackoverflow.com/questions/6250545/how-to-implement-full-row-selecting-in-gridview-without-select-button">How to implement full row selecting in GridView without select button?</a></p> <p>But I'm still slightly confused. After following that question, my rows are now clickable. But how do I implement it to do something after being clicked? Currently, I use a button to do what I need to the database per row:</p> <p>Here is the .aspx code:</p> <pre><code>&lt;Columns&gt; &lt;asp:ButtonField Text = "Click Me" CommandName = "Clicked" ButtonType = "Button" /&gt; ...other columns stuff &lt;/Columns&gt; </code></pre> <p>C# code behind:</p> <pre><code> protected void RowCommand(object sender, GridViewCommandEventArgs e) { //if button is clicked if (e.CommandName == "Clicked") { //go find the index on the gridview int selectedIndex = MsgInbox.SelectedIndex; if (int.TryParse(e.CommandArgument.ToString(), out selectedIndex)) { //do something with database } </code></pre> <p>Now that works beautifully. However, I don't want a button to be clickable, I want a entire row to be clickable. I know this is currently wrong, but this is what I have so far for the code:</p> <p>.aspx code</p> <pre><code> &lt;Columns&gt; &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;asp:LinkButton ID="SelectRow" runat="server" ForeColor="red" CommandName="Clicked"&gt;&lt;/asp:LinkButton&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; </code></pre> <p>C# code:</p> <pre><code> protected void Gridview_RowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onmouseover"] = "this.style.cursor='pointer';this.style.textDecoration='underline';"; e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';"; var selectButton = e.Row.FindControl("SelectRow") as Button; e.Row.Attributes["onclick"] = ClientScript.GetPostBackEventReference(selectButton, ""); </code></pre> <p>I get a simple null pointer exception when I do this, but I'm not really familiar with e.Row.Attributes so I really have no idea where this is failing and what I need to do to add the database logic.</p> <p>Thanks</p>

    1. COWhich line specifically is throwing an exception? What kind of exception? Note that you should use `as LinkButton` instead of `as Button`, since `SelectRow` is a `LinkButton`.

    2. COoh sweet! No error anymore now that I made it a LinkButton. Do you know where I should enter the logic for the database code (for example, click this row and do this to the database)? Right now when I click it nothing happens because I'm not sure where/how to add the code. Thanks!

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.
