  1. POajax update panel - imagebutton and button behaving differently?
    text
    copied!<p>I have an ajax panel (actually it' a Rad Ajax Panel - the behavior is similar to an Ajax Update Panel with everything in the ContentTemplate section and no Triggers), with an image button (asp:ImageButton) and a button (asp:Button).</p> <p>I notice that they behave differently - the image button advances to postback (Page_Load and Button_Click server functions), when the button doesn't!</p> <p>How can I achieve this behavior with the Button too? (Replacing the Button with an ImageButton solved the problem... Is there a way to maintain the Button and have the ImageButton's behavior?)</p> <hr/> <p>This is what my code looks like (two buttons, two click functions, and two client click functions):</p> <pre><code>&lt;telerik:RadScriptManager ID="RadScriptManager1" runat="server"&gt; &lt;/telerik:RadScriptManager&gt; &lt;div style="width: 800px;"&gt; &lt;telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1"&gt; &lt;telerik:RadScriptBlock ID="RadScriptBlock1" runat="server"&gt; &lt;script type="text/javascript"&gt; function validateSave() { // ... return true; } function validateAdd() { // ... return true; } &lt;/script&gt; &lt;/telerik:RadScriptBlock&gt; &lt;asp:Panel ID="Panel1" runat="server" Visible="false"&gt; &lt;fieldset&gt; &lt;legend&gt;New item&lt;/legend&gt; &lt;%--..........--%&gt; &lt;asp:ImageButton ID="Button4" runat="server" ImageUrl="~/App_Themes/ThemeDefault/images/add.gif" OnClientClick="return validateAdd();" OnClick="Button4_Click" /&gt; &lt;/fieldset&gt; &lt;%--..........--%&gt; &lt;asp:Button ID="Button2" runat="server" OnClientClick="return validateSave();" Text="Save" ToolTip="Save" OnClick="Button2_Click" /&gt; &lt;/asp:Panel&gt; &lt;/telerik:RadAjaxPanel&gt; &lt;telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"&gt; &lt;/telerik:RadAjaxLoadingPanel&gt; &lt;/div&gt; </code></pre>
