C# checkbox not showing textbox

[zamuel]

Hi everybody.

I fairly new in developing with Visual Studio 2003. This is the scenario

I would like to have a checkbox, which when checked is going to show a textbox. I believe this should be fairly easy to do, but I just cannot make it work. When checked the program is trying to execute something, but doesn't show the box.

I'm using following handler

private void CheckBox6_CheckedChanged(object sender, System.EventArgs e)
{
if (CheckBox6.Checked==true)
{
TextBox3roads.Height=72;
TextBox3roads.Visible=true;
}
else
{
Textbox3roads.Height=0;
Textbox3roads.Visible=false;
}
}

This is the HTML part of the control

asp:checkbox id="CheckBox" runat="server" Width="400px" AutoPostBack="True"></asp:checkbox>

So what am I missing here? Could someone give me some instruction?

Thanks.

hello

you have written

if(checkbox.checked==true)

instead try this

if(checkbox.checked)
{

//code
}


this works fine at my side

Yes, the problem was with "Web Form Designer generated code". Didn't know to add checkbox to this one. Thanks for the help.
