    <p>I asked <a href="https://stackoverflow.com/questions/4852474/asp-net-gridview-update-button-fires-edit-event-handler">this question</a> regarding a strange behaviour from a GridView control in ASP.Net (I'm using C#).</p> <p>For each row in my GridView there is an an 'Edit' and 'Delete' link. The edit for example has this <code>javascript:__doPostBack('gvwServers','Edit$0')</code> - So obviously the server is going to figure out someone has clicked to edit row <code>0</code> of <code>gvwServers</code>.</p> <p>Fair enough. If I click the Edit link I get a postback and the GridView is redrawn with the Edit button replaced with an 'Update' and 'Cancel' button. Standard behaviour. NOW - The 'Cancel' button has this link <code>javascript:__doPostBack('gvwServers','Cancel$0')</code> - just what I would expect Cancel row <code>0</code> of <code>gvwServers</code>. BUT The Update button has <code>javascript:__doPostBack('gvwServers$ctl02$ctl00','')</code>. This appears to not make any sense. And this appears to be the cause of my routine to handle Update not being fired.</p> <p>Why is ASP not outputting the correct postback arguments?</p> <p>My code is available at the link above.</p> <pre><code>&lt;asp:GridView ID="gvwServers" runat="server" class="gvwServers" AutoGenerateColumns="false" OnRowEditing="gvwServers_Edit" onrowcancelingedit="gvwServers_Cancelling" onrowdeleting="gvwServers_Deleting" onrowupdated="gvwServers_Updated" onrowupdating="gvwServers_Updating" AutoGenerateEditButton=true AutoGenerateDeleteButton=true&gt; &lt;columns&gt; &lt;asp:CommandField ShowEditButton="true" /&gt; &lt;asp:CommandField ShowDeleteButton="true" /&gt; &lt;asp:BoundField DataField="intServerID" visible="false" /&gt; &lt;asp:TemplateField HeaderText = "Server Name"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="lblServerName" runat="server" Text='&lt;%# Bind("txtName") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;EditItemTemplate&gt; &lt;asp:TextBox ID="txtServerName_Edit" runat="server" Text='&lt;%# Bind("txtName") %&gt;'&gt;&lt;/asp:TextBox&gt; &lt;/EditItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText = "Key"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="lblAppKey" runat="server" Text='&lt;%# Bind("txtApplicationKey") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;EditItemTemplate&gt; &lt;asp:TextBox ID="txtAppKey_Edit" runat="server" Text='&lt;%# Bind("txtApplicationKey") %&gt;'&gt;&lt;/asp:TextBox&gt; &lt;/EditItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText = "Connection String"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="lblConnString" runat="server" Text='************'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;EditItemTemplate&gt; &lt;asp:TextBox runat="server" ID="txtConnString_Edit" Width="300px" Height="100px" Text='&lt;%# Bind("txtConnectionString")%&gt;' TextMode="MultiLine" &gt;&lt;/asp:TextBox&gt; &lt;/EditItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/columns&gt; &lt;/asp:GridView&gt; </code></pre>

    1. COCan you show all your gridview code? (link above only shows the edit/delete) Might be something simple overlooked.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
