Introduction

In case of ImageRotator, we can use FileUpload control to upload my images.

Here I use it in a simple way.

Step 1

We use a image control (Image1), FileUpload control, button (Button1), HiddenField (for storing the file name) and a Save button to call the JavaScript function.

Step 2

On the click of Button1, we upload a file with the help of FileUpload1 and store the file name in HiddenField1 and show the image in the image control.

    string filename = FileUpload1.PostedFile.FileName.ToString();
    FileUpload1.SaveAs(Server.MapPath("~/") + filename);
    Image1.ImageUrl = filename.ToString();
    HiddenField1.Value = filename.ToString();

Step 3

On the click of Button2, we upload a file with the help of FileUpload2 and store the file name in HiddenField2 and show the image in the image control:

    string filename = FileUpload2.PostedFile.FileName.ToString();
    FileUpload2.SaveAs(Server.MapPath("~/") + filename);
    Image1.ImageUrl = filename.ToString();
    HiddenField2.Value = filename.ToString();

Step 4

On the click of Button3, we upload a file with the help of FileUpload3 and store the file name in HiddenField3 and show the image in the image control.

    string filename = FileUpload3.PostedFile.FileName.ToString();
    FileUpload3.SaveAs(Server.MapPath("~/") + filename);
    Image1.ImageUrl = filename.ToString();
    HiddenField3.Value = filename.ToString();

Suppose we add only three Images for ImageRotator.

Step 5

In the click of the Save Button (HTML control) we call the JavaScript function (show()) in the OnClick event.

<script language="javascript" type="text/javascript" >
    function show()
    {
        var a=document.getElementById('HiddenField1').value;
        document.getElementById('Image1').src=a;
        setTimeout("show2()",1000);
    }

    function show2()
    {
        var b=document.getElementById('HiddenField2').value;
        document.getElementById('Image1').src=b;
        setTimeout("show3()",1000);
    }
    
    function show3()
    {
        var b=document.getElementById('HiddenField3').value;
        document.getElementById('Image1').src=b;
        setTimeout("show()",1000);
    }
</script>

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
 
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
