Question

I add a css class to my li tag like following:

liComPapers.Attributes.Add("class", "NoDisplay");

Is there any way to remove this specific class (NoDisplay) from that li tag somewhere else in my code?

I have tried the following code but it is not working.

liComPapers.Attributes["class"] = ""; 

Thanks

I’ve just made a sample to test your code, and found that the following part will do exactly what you want:

 var newClassValue = liTest.Attributes["class"].Replace("NoDisplay", "");
 liTest.Attributes["class"] = newClassValue;

Tested and Working:
if (for some reason) the above code didn’t work, I would recommend another approach, which is similar to the previous, with another way to replace the class value

var newClassValue = liTest.Attributes["class"].Replace("NoDisplay", "");
liTest.Attributes.Remove("class");
liTest.Attributes.Add("class",newClassValue);
