Adding Controls at run time

[Praveen Naregal]

Hi all,

I am trying to add linkbuttons at run time. Here is the code.

//....
System.Web.UI.WebControls.LinkButton lbAcnt = new
System.Web.UI.WebControls.LinkButton();
Controls.Add(lbAcnt);
lbAcnt.ID = "lButton" ;
lbAcnt.Enabled = true;
lbAcnt.Visible = true;
lbAcnt.Text = "lButton" ;
lbAcnt.Click += new System.EventHandler(this.DisplayAcntDetails);
//..

I am getting the following error.
HttpException (0x80004005): Control 'lButton' of type 'LinkButton' must be
placed inside a form tag with runat=server.]

What is wrong here. How to set these runat = server property at runtime?

Thanks in advance

What it means is that the html element you are trying to add this control to
must have a "runat=server" attribute, such as this...

<TD id="test" runat=server></TD>

You will also have to add the button to a controls collection of the
container like this.

test.Controls.Add(lblAcnt);

Hi Felbrigg,

I am using Visual Studio .NET and C#. How do you specify this runat=server
attribute while creating the control runtime?

May I see your code? not the part but whole?
I wonder where you placed the linkbutton control.
and are you making composite custom control?

Your error state :
I am getting the following error. HttpException (0x80004005): Control
'lButton' of type 'LinkButton'
must be placed inside a form tag with runat=server.

Its very clear. All asp.net web control need to placed btw <form id="form1"
......runat="server">
<asp:LinkButton ....></asp:LinkButton>
</form>

now when you add your control dynamically either you add it to a placeholder
control, or another controls, control collection, which is already in btw
the form object with runat="server" or you add your control to the form
objects controls collection.

what you are doing is, you are adding a label to YOur pages controls
collection, and then adding a link button to your labels controls
collection. And NONE of this is going into your form objects controls
collection. So instead of adding it to the pages controls collection add it
to the pages form object.

Let me know if your having difficulty. This is very simple and not as
complicated as it seems.

Hi all,

I got the problem.It's rather very simple. You need to include
the following line and set the runat=server property.
lbAcnt.Attributes.Add("runat","server");

thanks for your suggestions
