<telerik:RadNumericTextBox ID="txt1" runat="server" MinValue="0"></telerik:RadNumericTextBox>

<td>

<telerik:RadNumericTextBox ID="txt4" runat="server" MinValue="0"></telerik:RadNumericTextBox>

</td>

</tr>

</table>

</telerik:RadAjaxPanel>

.CS:

        protected void btnUseDefault_Click(object sender, EventArgs e)
        {
           txt1.Value = 11.11;
        }

But after click the button, it postback. Please advice.

Hello Sayid,

To avoid post back on clicking the button(btnUseDefault), you would have to add the button inside the Ajax panel as shown below:
aspx:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="TheRadAjaxLoadingPanelResource1" >
  <asp:Button runat="server" ID="btnUseDefault" Text="Test" OnClick="btnUseDefault_Click"  />
  <table cellpadding="5" border="1" runat="server" ID="tblGameSetting">
       <tr>
          ......

Thanks
Princy.
