Question

I’m building a website using ASP and C# and I wanted to know if it’s possible to add a custom events to an asp control.

I want to add an OnClick, OnMouseDown, OnMouseUp (etc.) event to <asp:image>.

Is it possible?

Thanks in advance

Answer 1

yes you can do it this way.

HTML

 <asp:Image runat="server" ID="Image1"  />

CODE BEHIND

    protected void Page_Load(object sender, EventArgs e){

        this.Image1.Attributes.Add("onmouseup", "alert('this is the OnMouseUp event')");

    }

EDIT

  It can be do it using DHTML but as you may know 
  DHTML is the art of combining HTML, JavaScript, DOM, and CSS.

  protected void Page_Load(object sender, EventArgs e){
        //change the Image Url when the click event fire
        this.Image1.Attributes.Add("onclick", "this.src='image1.jpg'");

    }
