[Solved] Text property not updated

[Arild Bakken]

I'm using the RadTextBox control with the RadAjaxManager. When a dropdown is changed, an Ajax update is triggered and the UI is updated. At this point, I can get the Text property of the RadTextBox and all is fine. However, when I now fill out the form and click the submit button, the value I get from that RadTextBox is the value entered before the first Ajax update. Any changed performed afterwards are not recognized by the RadTextBox on the serverside. Example that demonstrates the issue:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" Height="200px" Width="300px">
<telerik:RadTextBox ID="RadTextBox1" runat="server"></telerik:RadTextBox>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /><br />
</telerik:RadAjaxPanel>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="Button1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>


Codebehind: 

protected void Button1_Click(object sender, EventArgs e) {
  Button1.Text = RadTextBox1.Text;
}

The first time the button is clicked, the text from the RadTextBox is set as the button's caption. Any subsequent edit of the box and click on the button will not update the button caption - the value returned from the RadTextBox1.Text stays the same as the first click. What am I doing wrong?

Hi Arild,

When using RadAjaxManger it is not necessary to use RadAjaxPanel - you can replace the ajax panel with a regular panel. Here is an example:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
         <telerik:AjaxSetting AjaxControlID="Button1">
              <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="Panel1" />
              </UpdatedControls>
         </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

<asp:Panel ID="Panel1" runat="server" Height="200px" Width="300px">
    <telerik:RadTextBox ID="RadTextBox1" runat="server"></telerik:RadTextBox>
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /><br />
</asp:Panel>
