    <p>I need to show a Master/Child data in a page and I have used multiple GridViews to achieve the same. So, I have created two GridViews (Parent &amp; Child) and now I want to fire the Button click event (i.e. btnLock) from the child gridview control and do some DB operations. So, I dont know how to achieve this. </p> <p>Please help.</p> <pre><code>&lt;asp:UpdatePanel ID="pnlUpdate" runat="server"&gt; &lt;ContentTemplate&gt; &lt;asp:GridView Width="100%" AllowPaging="True" ID="gvCustomers" AutoGenerateColumns="False" DataSourceID="sqlDsCustomers" runat="server" ShowHeader="False" OnRowCreated="gvCustomers_RowCreated"&gt; &lt;Columns&gt; &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;div class="group" id='&lt;%#String.Format("customer{0}",Container.DataItemIndex) %&gt;' onclick='showhide(&lt;%#String.Format("\"#customer{0}\"",Container.DataItemIndex) %&gt;,&lt;%#String.Format("\"#order{0}\"",Container.DataItemIndex) %&gt;)'&gt; &lt;asp:Image ID="imgCollapsible" CssClass="first" ImageUrl="~/Assets/img/plus.png" Style="margin-right: 5px;" runat="server" /&gt;&lt;span class="header"&gt; &lt;%#Eval("CustomerID")%&gt; : &lt;%#Eval("CompanyName")%&gt; (&lt;%#Eval("TotalOrders")%&gt; Orders) &lt;/span&gt; &lt;/div&gt; &lt;asp:SqlDataSource ID="sqlDsOrders" runat="server" ConnectionString="&lt;%$ ConnectionStrings:Northwind %&gt;" SelectCommand="SELECT [OrderID], [OrderDate], [RequiredDate], [Freight], [ShippedDate] FROM [Orders] WHERE ([CustomerID] = @CustomerID)"&gt; &lt;SelectParameters&gt; &lt;asp:Parameter Name="CustomerID" Type="String" DefaultValue="" /&gt; &lt;/SelectParameters&gt; &lt;/asp:SqlDataSource&gt; &lt;div id='&lt;%#String.Format("order{0}",Container.DataItemIndex) %&gt;' class="order"&gt; &lt;asp:GridView AutoGenerateColumns="false" CssClass="grid" ID="gvOrders" DataSourceID="sqlDsOrders" runat="server" ShowHeader="true" EnableViewState="false"&gt; &lt;RowStyle CssClass="row" /&gt; &lt;AlternatingRowStyle CssClass="altrow" /&gt; &lt;Columns&gt; &lt;asp:TemplateField ItemStyle-CssClass="rownum"&gt; &lt;ItemTemplate&gt; &lt;%# Container.DataItemIndex + 1 %&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:BoundField HeaderText="Order ID" DataField="OrderID" ItemStyle-Width="80px" /&gt; &lt;asp:BoundField HeaderText="Date Ordered" DataField="OrderDate" DataFormatString="{0:MM/dd/yyyy}" ItemStyle-Width="100px" /&gt; &lt;asp:BoundField HeaderText="Date Required" DataField="RequiredDate" DataFormatString="{0:MM/dd/yyyy}" ItemStyle-Width="110px" /&gt; &lt;asp:BoundField HeaderText="Freight" DataField="Freight" DataFormatString="{0:c}" ItemStyle-Width="50px" ItemStyle-HorizontalAlign="Right" /&gt; &lt;asp:BoundField HeaderText="Date Shipped" DataField="ShippedDate" DataFormatString="{0:MM/dd/yyyy}" ItemStyle-Width="100px" /&gt; &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;asp:Button ID="btnLock" Text="Lock" CommandName="Lock" CommandArgument=&lt;%# Eval("OrderID") %&gt; runat="server" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/div&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; </code></pre> <p>Thanks</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.

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