Disabling And Enabling A Button During Postback In Asp.net

I'm trying to disable a button and change its text while doing a postback and then i want to change the text back to normal when postback is complete. , ClientScript.GetPostBackEventReference(button, string.Empty),text)); }

Solution 2:

You forgot to return true.

<asp:ButtonID="b_Generate"runat="server"onclick="b_Generate_Click"OnClientClick="this.disabled = true; this.value = 'Please Wait...'; return true;"Text="Generate PPT"UseSubmitBehavior="false"style="z-index: 1; left: 05px; top: 50px; position: absolute; width: 110px;"BorderStyle="Ridge"Font-Bold="True"ToolTip="click here"
/>
