    <p>I have a button on my ASP.NET page, which fetches some data from my database and displays it on a gridview. </p> <p>This process takes a while, so I thought I'll add an updateprogress AJAX control. Now when I click the button, the updateprogress image shows up and data is being fetched from my database successfully (I checked this from some logs that I have in my DB). But there are 2 issues:</p> <p>(1) The updateprogress image shows only for about 2 minutes. But my buttonclick event takes about 5 minutes to complete. Basically the updateprogress stops showing up even before my task is complete, which defeats its purpose.</p> <p>(2) GridView doesn't show up. It shows up correctly if I don't use scriptmanager/AJAX.</p> <p>Any ideas?</p> <p>Some relevant code snippets:</p> <pre><code>&lt;div style="position: absolute; top: 300px; left: 19px; width: 568px; height: 48px;"&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; &lt;asp:Button ID="btnGenerateReport" runat="server" Height="37px" Text="Generate Report" Width="132px" onclick="btnGenerateReport_Click" /&gt; &lt;/td&gt; &lt;td class="style5"&gt; &lt;asp:ScriptManager ID="ScriptManager1" runat="server" /&gt; &lt;asp:UpdatePanel runat="server" id="Panel"&gt; &lt;ContentTemplate&gt; &lt;asp:UpdateProgress ID="PageUpdateProgress" runat="server"&gt; &lt;ProgressTemplate&gt; &lt;img runat="server" src="updateprogress.gif" style="position: static; width: 32px;"&gt; &lt;/img&gt;&lt;/ProgressTemplate&gt; &lt;/asp:UpdateProgress&gt; &lt;div style="position: absolute; top: 423px; left: 9px; width: 795px; height: 984px;"&gt; &lt;asp:GridView ID="Report" runat="server" AllowSorting="True" AutoGenerateColumns="False" Height="622px" BorderStyle="Solid" Width="779px" PageSize="100" HorizontalAlign="Center"&gt; &lt;Columns&gt; &lt;asp:BoundField HeaderText="AccountId" DataField="AccountId"&gt; &lt;ControlStyle BorderStyle="Solid" Width="20px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField HeaderText="User Name" ReadOnly="True" DataField="UserName"&gt; &lt;ControlStyle Width="50px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField HeaderText="C2" ReadOnly="True" DataField="C2"&gt; &lt;ControlStyle BorderStyle="Solid" Width="20px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField HeaderText="C1" ReadOnly="True" DataField="C1"&gt; &lt;ControlStyle BorderStyle="Solid" Width="20px" /&gt; &lt;/asp:BoundField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/div&gt; &lt;/ContentTemplate&gt; &lt;Triggers&gt; &lt;asp:AsyncPostBackTrigger ControlID="btnGenerateReport" EventName="click" /&gt; &lt;/Triggers&gt; &lt;/asp:UpdatePanel&gt; &lt;/td&gt; &lt;td&gt; &lt;asp:Button ID="btnExportToExcel" runat="server" Text="Export To Excel" Height="37px" Width="132px" onclick="btnExportToExcel_Click" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; </code></pre> <p>Codefile part:</p> <pre><code>protected void btnGenerateReport_Click(object sender, EventArgs e) { FetchAccounts(); long startId = FetchAuditData(); AggregateAuditData(startId); dsAnalysisReport = GenerateDataSet(); if (dsAnalysisReport == null || dsAnalysisReport.Tables.Count == 0) lblErrorText.Text = "No Data Found for the input information"; else BindData(dsAnalysisReport); } public void FetchAccounts() { using (var sqlConnection = new SqlConnection(ConnectionString)) { sqlConnection.Open(); cmdstring = @"[spo_FetchAccounts]"; cmd = new SqlCommand(cmdstring, sqlConnection) { CommandType = CommandType.StoredProcedure }; cmd.CommandTimeout = 100000; cmd.Parameters.Add("@MaxActivationDate", SqlDbType.DateTime); cmd.Parameters["@MaxActivationDate"].Value = DateTime.Parse(txtStartDate.Text) - new TimeSpan(1, 0, 0, 0); cmd.ExecuteNonQuery(); sqlConnection.Close(); } } public long FetchAuditData() { using (var sqlConnection = new SqlConnection(ConnectionString)) { sqlConnection.Open(); cmdstring = @"[spo_GetComparisonData]"; cmd = new SqlCommand(cmdstring, sqlConnection) { CommandType = CommandType.StoredProcedure }; cmd.CommandTimeout = 100000; cmd.Parameters.Add("@StartDate", SqlDbType.DateTime); cmd.Parameters["@StartDate"].Value = txtStartDate.Text; cmd.Parameters.Add("@EndDate", SqlDbType.DateTime); cmd.Parameters["@EndDate"].Value = txtEndDate.Text; SqlParameter returnValue = new SqlParameter("@Return_Value", SqlDbType.BigInt); returnValue.Direction = ParameterDirection.ReturnValue; cmd.Parameters.Add(returnValue); cmd.ExecuteNonQuery(); long startId = long.Parse(cmd.Parameters["@Return_Value"].Value.ToString()); sqlConnection.Close(); return startId; } } private void AggregateAuditData(long startId) { using (var sqlConnection = new SqlConnection(ConnectionString)) { sqlConnection.Open(); cmdstring = @"[spo_ComparisonTable]"; cmd = new SqlCommand(cmdstring, sqlConnection) { CommandType = CommandType.StoredProcedure }; cmd.CommandTimeout = 100000; cmd.Parameters.Add("@StartId", SqlDbType.Int); cmd.Parameters["@StartId"].Value = startId; cmd.ExecuteNonQuery(); sqlConnection.Close(); } } public DataSet GenerateDataSet() { using (var sqlConnection = new SqlConnection(ConnectionString)) { sqlConnection.Open(); cmdstring = @"SELECT * FROM XAccounts"; cmd = new SqlCommand(cmdstring, sqlConnection); DataSet ds = new DataSet(); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(ds); sqlConnection.Close(); if (ds.Tables.Count &gt; 0 &amp;&amp; ds.Tables[0].Rows.Count &gt; 0) return ds; return null; } } private void BindData(DataSet ds) { BindReportGrid(Report, ds.Tables[0]); } private void BindReportGrid(GridView gridToBind, DataTable dataTableToBind) { gridToBind.DataSource = dataTableToBind; gridToBind.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.
