Image URL instead of image data field

[Saeid Kdaimati]

Hi,

Can I set images URL from a data source instead of image data field? In my situation, we save only image url in database.

Thanx

Hello Saeid,

The RadImageGallery's DataImageField property accepts a binary image or a string representing the URL to the image from the database and it determines internally whether the data is a URL or a binary image.

An online demo for the requirement that you have could be found at the following link:

• ImageGallery - Declarative and Programmatic Binding

And following is a very simple example which demonstrated how to use the data source with URL for the images:

<telerik:RadImageGallery runat="server" ID="RadImageGallery1" OnNeedDataSource="RadImageGallery1_NeedDataSource"
     DataImageField="imageURL" DataTitleField="imageTitle"></telerik:RadImageGallery>

And the code-behind:

protected void RadImageGallery1_NeedDataSource(object sender, ImageGalleryNeedDataSourceEventArgs e)
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(int));
    table.Columns.Add("imageURL", typeof(string));
    table.Columns.Add("imageTitle", typeof(string));
    table.Rows.Add(1, "http://demos.telerik.com/aspnet-ajax/image-gallery/examples/data-binding/server-side-binding/declarative-and-programmatic-binding/images/Arc_de_Triomf.jpg", "Arc de Triomf");

    (sender as RadImageGallery).DataSource = table;
}

Hope that helps.
