Hi guys,

I have a table, and one of the columns is it works perfectly when I set the picture value from the data source.

But we have some invalid images, and we want to validate the image in the . So how can I set the image in the or maybe get the image path in the  function.

 

This is my code, tried to fill the TextBox9 with the image path, but not working properly:

 

Private Sub PictureBox4_ItemDataBinding(sender As Object, e As EventArgs) Handles PictureBox4.ItemDataBinding
        Dim picture As Telerik.Reporting.Processing.PictureBox = DirectCast(sender, Telerik.Reporting.Processing.PictureBox)

        Dim s As String = String.Format("= '{0}' + {1}", "/portals/0/PI/ProductImages/", TextBox9.Value.Replace("=", ""))

        picture.Image = Image.FromFile(s)
        TextBox13.Value = s
    End Sub

thanks

try to get in the code behind the value of the field with the path of the image. It doesn't return the value, just the column field

like:
C:\inetpub\wwwroot\JA Russell Full\1_DEV\DNN\= '\portals\0

\PI\ProductImages\' + Fields.ImageFileName

I just need a way to access the field in the DataSource of the current item in the data binding event

Hi Gustavo,

The recommended approach is to use a custom function getting the field as a parameter. In the function you can implement the validation and return the correct path or if you prefer an Image object.

The above linked article contains an example.

Hi Stef,

   we have same issue with the report image like the picture that I have attached. When picture load a product image if there are error it shows error massage.that is fine. But that error broke the report in to two pages, because the error message width is two big than image icon.and I gave tried set column width and Layout Sizing. It doesn't work.It just can not get ride of those error messages.

     Do you know any better way to hide ,or try catch,or show them in a small size? thanks

Hi Lucaso,

The recommended approach is the same - use a custom function to validate the image data or return a default image instead. This will prevent red errors which can change the document layout.
