如何检查是否设置了样式属性？

Question

I can set a label in code behind to be underlined

Label1.Style.Add("text-decoration", "underline");

But how can I check if a Label is underlined or not? Something like this?

if(Label1.Style.Add("text-decoration") == "underline")
if(Label1.Style[HtmlTextWriterStyle.TextDecoration] == "underline")

Both do not work!

Answer 1

If you need to test a certain style and your using web forms I recommend checking the data attribute of that specific style. D Stanley above gave the following code snippet that would work to check for a Boolean value.

Label1.Style["text-decoration"] == "underline"
