    <p>I have a gridview that is being populated from a sql database. When the results are displayed I am linking the district #'s to a new contact page for each one. Ex. d1.aspx, d2.aspx, d3.aspx etc. On each of those pages there is a link to return back to the orginal page. When this happens the original page is refrreshed and the previous gridview results are gone. Is it possible to stop this from happening or is there a better way to do something like this? </p> <p></p> <pre><code>&lt;Columns&gt; &lt;asp:BoundField HeaderText="Name" DataField="school" /&gt;&lt;asp:BoundField /&gt; &lt;asp:TemplateField HeaderText="District" HeaderStyle-HorizontalAlign="Left"&gt; &lt;ItemTemplate&gt; &lt;asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='&lt;%# Eval("district", "cdms/d{0}.aspx") %&gt;' Text='&lt;%# Eval("district") %&gt;'&gt; &lt;/asp:HyperLink&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;EmptyDataTemplate&gt; &lt;span style="color: rgb(255, 0, 0);"&gt;No records found!&lt;/span&gt; &lt;/EmptyDataTemplate&gt; &lt;/asp:GridView&gt; </code></pre> <p>Codebehind:</p> <pre><code>protected void btnSubmit_Click(object sender, EventArgs e) { BuildGridView1(); GridView1.DataBind(); GridView1.Visible = true; } private void BuildGridView1() { GridView1.DataSource = new Select(District.Schema.TableName + ".*") .From(District.Schema) .Where(District.Columns.Zip).IsEqualTo(this.txtZip.Text) .OrderAsc(District.Columns.Zip) .ExecuteDataSet(); } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { BuildGridView1(); GridView1.PageIndex = e.NewPageIndex; GridView1.DataBind(); } </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.
