C# cursor positioning with T.Select(T.Text.Length, 0);

I'm trying to position the cursor at the end of a textbox with.....

<asp:TextBox ID="TextBox1" AutoPostBack="true" EnableViewState="true" 
   runat="server" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>

and then 

TextBox1.Select(TextBox1.Text.Length, 0);

but Visual Studio says:

"Error  5   No overload for method 'Select' takes 2 arguments D:\Doc\t.aspx.cs"

How to do it?

Many thanks.

Regards.

Gius.

You can do that only with JavaScript. Most simple way would be to focus the textbox then add empty string to its value, on page load event. Just add this code into your <head> section:

<script type="text/javascript">
window.onload = function() {
    var oInput = document.getElementById("<%=TextBox1.ClientID%>");
    oInput.focus();    
    oInput.value += "";
};
</script>

And it will have the desired effect as far as I can tell.

You probably read of System.Windows.Controls.TextBox.Select or of System.Windows.Forms.TextBoxBase.Select.

Sadly System.Web.UI.WebControls.TextBox doesn't implement the Select method.
