change table cell style in vb code

Web Programming9
asp.net 2.0 using vwd

I'm trying to chagne the border of a table cell in my vb code but cannot

seem to do it. The cell has an ID of "tdAlert"

If txtAlert.Text <>"" Then

tdAlert.Style = "width: 547px; border-left-color: red;

border-bottom-color:

red; border-top-style: solid; border-top-color: red; border-right-style:

solid; border-left-style: solid; border-right-color: red;

border-bottom-style: solid;"

Else

tdAlert.Style = "width: 547px;"

End If

apparently tdAlert doesn't exist. I've saved the project thinking that maybe

intellisense would not find it if I didn't save it with the new ID but that

didnt' solve the problem. Any ideas on how this can be done? I just need a

red border around the cell under certain conditions.

Thanks,

Keith

In order to access the td as ASP.NET control it needs, in addition to an id

attribute, a runat="server" attribute. This makes it a HtmlTableCell.

You can not assign a style string directly since its an instance of

CssStyleCollection. This isn't a good approach anyway. A css class would

be better. The HtmlTableCell doesn't expose a CssClass attribute so you

need to add it via the Attributes collection.

The HtmlTableCell has a Width property so you can assign the 547px width to

that property.

Add the following mark up to your <head>:-

<style type="text/css">

td.highlight {border:1px solid red;}

</style>

Then your code becomes:-

If txtAlert.Text <>"" Then

tdTest.Attributes.Add("class", "highlight");

Else

tdTest.Attributes.Remove("class");

End If

Show how you define tdAlert in the .aspx page.

Re:change table cell style in vb code

Thanks Anthony. That worked. But I had to do some more research because I

still was unable to access my table cell in code:

www.velocityreviews.com/forums/t372741-how-to-access-html-controls-fr">www.velocityreviews.com/forums/t372741-how-to-access-html-controls-fr

om-code-behind-.html (Imports

System.Web.UI.HtmlControls)

Works fine now.
