Text box value comes properly  as per its binging expr. but for picture box it says invalid image data while processing picutre box.

Hi Manish,

Please check how the PictureBox.Value property is set to an expression in the PictureBox help article. There is also an example in the local demos located under C:\Program Files (x86)\Telerik\Reporting Q1 2013\Examples\CSharp\ReportLibrary\ProductCatalog by default - check for ictureBox1.Value.

I hope this helps.

Have you tried the new visualization options in Telerik Reporting Q1 2013? You can get them from your account.

Hi Stef,

Thanks. I got image in picturebox but when i put it in panel with text box it does not show image. I want to bind image and text in one column togather.

Or i can have separate column for picturebox but in that case i will have to merge two column headers of image and data text columns.

Please help in either case.

Thanks,
Manish

Hi Manish,

Please check the attached sample report definition. It illustrates a Table item bound to a SqlDataSource component, which retrieves data from AdventureWorks database. In a single cell of the table is added a Panel item on which we placed PictureBox and TextBox item for the example.

If you need further help, we need to know the report definition and what data is passed to it.

Hi, I had the same error and I solved it by simply deleting "using(MemoryStream ms ..."

 

In my code, I create a method to convert image blob to System.Drawing.Image (the only type of image that Telerik Reporting digests)

public static System.Drawing.Image GetImageFromByteArray(byte[] imageBlob)
        {
            System.Drawing.Image result = null;
            if (imageBlob != null)
            {
                MemoryStream ms = new MemoryStream(imageBlob);//you mustn't use "using MemoryStream ..."
                result = System.Drawing.Image.FromStream(ms);

            }
            return result;
        }
