Aspx:

<asp:UpdatePanel ID="upGrid" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<table style="width:750px">
<tr align="center">
<td align="center" class="style18">
<table border="0" style="border-color: #3E6C13; background-color: #669900; width: 590px; height: 20px; margin-bottom: 0px;">
<tr align="center">
<td class="srchBtnOption" align="center">
<asp:Button ID="btnProcess" runat="server" Height="25px" class="btn" onclick="btnProcess_Click" Text="Process" Width="150px" />
<br />
<br />
</td>
</tr>
</table>
</td>
</tr>
<tr align="center" >
<td align="center">
<asp:Label ID="lblMsg" runat="server" ForeColor="Maroon" Height="18px" EnableViewState="False"></asp:Label>
<%strMsg.ToString(); %>
<asp:HiddenField ID="hdnMsg" runat="server" />
</td>
</tr>
<tr align="center">
<td align="center">
<asp:Timer ID="tmrWrprDet" runat="server" Interval="3600" ontick="tmrWrprDet_Tick"></asp:Timer>
<asp:GridView ID="uxGridViewCJ" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" BorderColor="#669900"
BorderStyle="Ridge" BorderWidth="2px" CellPadding="1" CellSpacing="1"
EmptyDataText="No Records Found!.."
onpageindexchanging="uxGridViewCJ_PageIndexChanging"
onsorting="uxGridViewCJ_Sorting" PageSize="10">
<RowStyle backcolor="White" font-italic="true" ForeColor="Black" />
<Columns>
<asp:BoundField DataField="START_DATE" HeaderText="Start_Date"
ItemStyle-HorizontalAlign="Center" SortExpression="START_DATE">
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="END_DATE" HeaderText="End_Date"
ItemStyle-HorizontalAlign="Center" SortExpression="END_DATE">
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
</Columns>
<HeaderStyle BackColor="#333300" ForeColor="White" />
</asp:GridView>
</td>
</tr>
</table>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnProcess" />
</Triggers>
</asp:UpdatePanel>

Page.cs:

sample code:

protected void btnProcess_Click(object sender, EventArgs e)
{
//Asyncwebmethod calling
obj.webmethodAsync();
lblMsg.Text = "Labeled Sucessfully";

//Grid binding
da = new OracleDataAdapter(cmd);
cb = new OracleCommandBuilder(da);
ds = new DataSet();
da.Fill(ds);
uxGridViewCJ.DataSource = ds.Tables[0];
uxGridViewCJ.DataBind();
uxGridViewCJ.Visible = true;
}

Hi,

Try to add Asyncpostbacktrigger to the button click event.

Thanks,
