    text
    <p>I am using a big form, and in this form I have about 3 grids and many texboxes, I would like to create new elements in these grids without needing to refreshing all the page, so I can post all the form at once.</p> <p>I am trying to make the operations of <strong>Update</strong>, <strong>Delete</strong> and <strong>Add</strong> only on the client-side, without any post.</p> <p><strong>EDITED</strong></p> <p>I successfully achieved these operations using AJAX calls and using a <strong>ViewState</strong> as a <strong>DataTable</strong>. This because of the attribute <strong>CallBackMode</strong>, but in my opinion is doing an unecessary POST, even if it is an AJAX call, since it all could be handled only on the client-side, by javaScript.</p> <p>My grid is like bellow.</p> <pre><code>&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"&gt; &lt;ContentTemplate&gt; &lt;asp:Panel ID="Panel2" runat="server"&gt; &lt;obout:Grid ID="Grid1" AllowPageSizeSelection="false" AllowSorting="false" AllowMultiRecordSelection="false" AllowAddingRecords="true" FolderLocalization="~/Localization/Grid" FolderStyle="~/Styles/grid/premiere_blue" AutoGenerateColumns="false" DataKeyNames="id" AllowPaging="false" runat="server" Serialize="true" CallbackMode="true" ClientIDMode="Static"&gt; &lt;Columns&gt; &lt;obout:Column ID="Column1" Visible="false" HeaderText="Edit" Width="100" /&gt; &lt;obout:Column ID="Column2" DataField="pro_ncm" HeaderText="NCM" runat="server" Width="20%" /&gt; &lt;obout:Column ID="Column3" DataField="pro_descricao" HeaderText="Principais Produtos Fabricados" Width="20%" Wrap="true" runat="server" /&gt; &lt;obout:Column ID="Column4" DataField="pro_capacidade" HeaderText="Capacidade Produtiva/Ano" Width="20%" Wrap="true" runat="server" /&gt; &lt;/Columns&gt; &lt;/obout:Grid&gt; &lt;/asp:Panel&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; </code></pre>

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.
