Question

I have asp button, which functionality is for deleting the item. Button is inside the update panel. I have datalist in that I have adding the Item and with every time I have a checkbox. I have 2 button Select All and Clear All, I am selecting all the item with my Select All button that is JQuery Code after that I am trying to delete the time. when I am selecting the item one by one then its working fine, when selecting all items then its not working.

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always">
    <ContentTemplate>
       <asp:Button ID="Button1" runat="server" Enabled="false" Text="Delete" 
           OnClientClick="return confirm('Are you sure?');$.loading({ mask: true, effect: 'ellipsis update' });" 
           OnClick="Button1_Click" />
       </ContentTemplate>
</asp:UpdatePanel>

HTML it is generating..

<div id="Tab1_UpdatePanel1">
      <input type="submit" id="Tab1_Button1" value="Delete Image" name="Tab1$Button1">
</div>

JQuery for Enabling disabling Button1

  $("#[id$='btnCheckAll']").click(function () {
     $("#<%= dlst1.ClientID %> input:checkbox").attr("checked", "checked");
     $("#<%=Button1.ClientID %>").removeAttr('disabled');
  });

  $("#[id$='btnUnCheck']").click(function () {
       $("#<%= dlst1.ClientID %> input:checkbox").removeAttr("checked");
       $("#<%=Button1.ClientID %>").attr('disabled', 'disabled');
  });

and on page_load also I am making Button1.Enable=false; and when I am selecting any item I directly without using checkbox i am making Button.Enabled=true over there.

Button functionality is working fine but Confirm box is not showing, I checked this Question also but not working for me.

When I am making my button enable then its working fine, But I have the condition where I need to disable the button and based on some condition i am enabling the button. then its not working.

Please someone help me?
