In my project, there is css class to control the design of everything.

Now I want to change dynamically the value / properties in css class if I click buttons.

Can anyone solve my problem?

Thanks a lot :-)

I think you want to change the entire style of div.
For example:
1.Set the runat attribute and Id to the div so you can access it from the code behind.
2. Acess it from the code behind.Already some of them has given the syntax.just follow it.In our case,i'm changing the style of div to another class.
tableContainer.Attributes.Add("class","container-new")
Hope this helps.

Use this-

Syntax1:
contrrolname.Style.Add("attrb","value")
Ex :txtName.Style.Add("Background-color", "#ccc");

if you want to change class then use 2

In code behind :

Syntax1:
contrrolname.Style.Add("attrb","value")

Ex :txtName.Style.Add("Background-color", "#ccc");

Syntax2:
contrrolname.Attributes.Add("class","classname")

Ex: txtName.Attributes.Add("class", "clstest");
