ASP.net shorthand in TextBox

Question

I am trying to do the following:

<asp:TextBox ID="txtName" runat="server" Text="<%= Name %>" />

When I execute my page it gets output as <%= Name %> instead of actually doing a response.write.

I tried modifying it to use the <% Response.Write(Name) %> instead but it did the same thing, putting the text there instead.

I can do this just fine:

<input type="text" value="<%= Name %>" />

That will actually work. Why doesn't this work when I use the TextBox control? Is there another way I'm supposed to do this?

Answer 1

Either use code behind:

txtName.Text = Name;

Or, add Page.DataBind() in your code behind and change the syntax of your control to:

<asp:TextBox ID="txtName" runat="server" Text="<%# Name %>" />

Note the # rather than the = . # represents a data-binding expression

Answer 2

Because the control is rendered differently than a literal. Use the codebehind to set the Text property.
