使用css隐藏Asp.net中的控件

Question

i am trying to make the control not visable through the css but still the control is been shown.

i tried doing like this

html1.Visible = false;

but this creates an gap in the menu where is been used

HtmlAnchor html1 = (HtmlAnchor)holder.FindControl("lblA1");
html1.Attributes.Add("class", "display:none");

i want to hide the control and do not want to display the gap there how can we achive this. any help on this would be great

Answer 1

You just need to use style instead of class :

html1.Attributes.Add("style", "display:none");

You may also consider the option of making a CSS style like:

.hidden
{
   display:none;
}

And then apply it via 'class':

html1.Attributes.Add("class", "hidden");

Answer 2

If you want to add more than one property in style element in that case use Style property instead of Attributes property like this example....

HtmlAnchor html1 = (HtmlAnchor)Page.FindControl("lblA1");
html1.Style.Add("display", "none");

Answer 3

You can attach this class to button using above methods Very helpful when the button is taking the space , which it shouldn't be

<style>
 .hideAspButton
  {
   position: absolute;
   visibility: hidden;
  }
</style>
