I have some code like this:

            loTextbox = loUserControl.FindControl("LXFrameworkLabel")
            loTextbox.Width = 281

This replaces the width of a textbox control in an .aspx page:

<asp:TextBox ID="LXFrameworkLabel" runat="server" width="263" style="border-right: 0px;"></asp:TextBox>

This works.

Now, if I would like to style everything in the aspx page such as:

<asp:TextBox ID="LXFrameworkLabel" runat="server" style="width: 263px; border-right: 0px;"></asp:TextBox>

...this won't work.

Instead, .NET will add another width definition on the control.

What approach are you using from the .NET code to make sure the width will always be overwritten, no matter if it is a property of the textbox control or within the style?
