This Is the HTML code

function ClearingLR(){
document.getElementById("txt_Acronym").value=Trim(document.getElementById("txt_Acronym").value);
document.getElementById("txt_Rolename").value=Trim(document.getElementById("txt_Rolename").value);
}

This Is the HTML code

No, that's your Javascript.

That error message is telling you exactly what the problem is. Either an element with that id does not exist in your html or it does exist but you are calling the function before the element has been loaded.

the code of the control is:

<asp:TextBox ID="txt_Date" TabIndex="2" runat="server" MaxLength="25" onchange="ClearingLR(this);" />

so where are the elements you refer to in your js function?

Get the complete HTML source of your page from your browser's "view source" option and post it here.
