The way you're trying to bind images is not ok. You may want to go through this post and follow the way how to do it:

Now it's running without bugs. But after running when I upload a picture to bind to my "image" tool its doesnt.
See what I wrote as code but I receive this error message:
Databinding methods such as Eval(), and Bind() can only be used in the context of a databound control.
protected void Image()
    {
        DirectoryInfo dir = new DirectoryInfo(MapPath("Images"));
        FileInfo[] files = dir.GetFiles();
        ArrayList listItems = new ArrayList();
        foreach (FileInfo info in files)
        {
            listItems.Add(info);
        }
        //Here
        Image1.DataBind();
       }

Hi,

i checked your code there is no method with name Images1();
that's why you are getting error.

in your code there is a method

protected void Image()
    {
......
}

i think you want to call this method.

so in page load change this as below code.

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
    {
        Image();
    }
    }

Hi Divin,

As I can see, the error is self-explanatory. It couldn't find Images1() and that's it. Check with your code if you've implemented Images1() method somewhere. It's missing.

Hope you got the point.
