Just put the Panel1
control into UpdatePanel with UpdateMode="Conditional"
. By the way, rewrite chkRevVal_CheckedChanged
as this:
this.txtValComm.Enabled = chkRevVal.Checked;
if (txtValComm.Enabled)
txtValComm.Focus();

Is this possible? I've got an AJAX TabContainer, and 3 tabs in the container. On Tab #2, I've got a checkbox that, when checked, enables a textbox. When the checkbox is unchecked, the textbox should be disabled.
I've got this code in my ASP form:
<AJAXControls:TabContainer runat="server" ID="tabContainer" Height="373" Width="900" >
<AJAXControls:TabPanel ID="firstTab" HeaderText="First Tab" runat="server">
<ContentTemplate>
<asp:Label ID="Label1" runat="server">You are in the First tab.</asp:Label>
</ContentTemplate>
</AJAXControls:TabPanel>
<AJAXControls:TabPanel ID="secondTab" HeaderText="Second Tab" runat="server">
<ContentTemplate>
<div>
<asp:Panel ID="Panel1" runat="server" Height="70px" style="margin-left: 19px"
Width="860px" BorderStyle="Groove" BorderWidth="2px">
<table>
<tr>
<td width="170">Review Validated:</td>
<td width="50"><asp:CheckBox ID="chkRevVal" runat="server" Text=" " oncheckedchanged="chkRevVal_CheckedChanged" AutoPostBack="true" /></td>
<td width="40"></td>
<td width="170">Validation Comments:</td>
<td width="380" rowspan = "4"><asp:textbox id="txtValComm" runat="server" textmode="multiline" rows="4" Width="380px"></asp:textbox></td>
</tr>
<tr></tr>
<tr></tr>
<tr></tr>
</table>
</asp:Panel>
</ContentTemplate>
</AJAXControls:TabPanel>
</AJAXControls:TabContainer>
And I've got this in my code-behind:
protected void chkRevVal_CheckedChanged(object sender, EventArgs e)
{
if (chkRevVal.Checked == true)
{
this.txtValComm.Enabled = true;
this.txtValComm.Focus();
}
}
The problem is, when I check the box, the TabContainer goes back to tab #1 every time. Is there a way to keep it on tab #2 after I've checked the checkbox?
