Attribute 'onchange' is not a valid attribute of element 'TextBox'

[Joe Kovac]

Hi!

Using:

<asp:TextBox ID="TextBox1" runat="server"
onchange="oncha nge()"></asp:TextBox>

I get:

Warning 1 Validation (ASP.Net): Attribute 'onchange' is not a valid
attribute of element 'TextBox'.

How to avoid this warning? What should I do to "fix" it?

Possibly you styles or like that???

Thanks

Joe

That's because you're using a webcontrol, which doesn't have an onchange
method.

How to avoid this warning? What should I do to "fix" it?

In code-behind:

TextBox1.Attrib utes.Add("oncha nge", "onchange() ;");

Also, see my previous message advising against this... :-)

I guess this way MS wants to point out clearly, that you use non MS
properties. Putting it to the .aspx page works, but produces a not
beautiful warning.
