Hello Michael,
Victor is right and I have also tested it on my side.
By the way, in order to stop the System.Web.UI.WebControls.Table() class from rendering the "border-collapse:collapse"
style property in the <TABLE> tag, we could set CellSpacing to something other than 0.
There isn't a way to get rid of border-collapse if you set CellSpacing to 0.
Perhaps there should have been a way to override this behavior. Tables with cellspacing=0 with the borders collapsed don't
look like they have really 0 cellspacing (visually), because each cell has a border. Therefore to make it appear that there is
absolutely no space between cells, we add this style attribute.
Here's what you should do:
1. Write a MyTable control deriving from Table
2. In there override CreateControlStyle to plug in a derived style
protected override Style CreateControlStyle() {
return new MyTableStyle(ViewState);
}
3. Write the MyTableStyle class deriving from TableStyle like so:
public class MyTableStyle : TableStyle {
private bool _rendering;
public override int CellSpacing {
get {
if (_rendering) {
return -1;
}
return base.CellSpacing;
}
set {
base.CellSpacing = value;
}
}
public override void AddAttributesToRender(HtmlTextWriter writer, WebControl owner) {
try {
_rendering = true;
base.AddAttributesToRender(writer, owner);
}
finally {
_rendering = false;
}
int n = CellSpacing;
if (n >= 0) {
writer.AddAttribute(HtmlTextWriterAttribute.CellSp acing, n.ToString(CultureInfo.InvariantCulture));
}
}
}
That should do the trick... of course this is email code based on memory of the code, so it might need small modifications to
fully work.
Thanks very much for participating the community.
