Export image column

[Marco]

I have to export a radgridview (winforms) with an image column.
I have stored in sql database the image and I defined the column like this:

gv.MasterTemplate.Columns["image"].Width = 120;
gv.MasterTemplate.Columns["image"].DataType = typeof(Image);
gv.MasterTemplate.Columns["image"].ImageLayout = ImageLayout.Zoom;

I can see the images without problem in the radgridview, but if I try to export grid with telerik reporting (Q3 2011), I cannot see image (in the column cells it write "System.Drawing.Bitmap")
this is the code that I use when I create the table to export from the masterview:

System.IO.MemoryStream stmBLOBData = new System.IO.MemoryStream((byte[])gridViewTemplate.Rows[row].Cells[cell].Value);
Image image = Image.FromStream(stmBLOBData);
tableRow[cell] = image;

thanks all,
Marco

Hello Marco,

Thank you for writing.

I suppose that you are using RadGridReportingLite to export RadGridView to our Reporting tool. I am not able to understand your exact goals very well and therefore I would kindly ask you to provide me with more information about them. If exporting to Reporting is not what you are actually looking for, but instead you need to export to PDF or print RadGridView's data, I am happy to inform you that these features are natively supported by RadGridView and you do not need to export it to Reporting first. Exporting to PDF was introduced in Q2 2010, and printing RadGridView's data was introduced in Q1 2012.

If these tips still do not help you achieve your goal, please describe your scenario in greater detail. We may find an easier path than the path you have followed.

I am looking forward to you reply.

All the best,

I've install Q1 2012.
Now I tried to do a simple ExportToPDF with ExportVisualSettings=true but in the pdf file the image column contains "System.Bitmap" string instead of the images.
The column is defined like this:
gv.MasterTemplate.Columns["image"].DataType = typeof(GridViewImageColumn);
and contains a db column (sql type image)
how can I export a image column?

thank you

Hi Marco,

Thank you for your reply.

Currently, we do not support exporting images. I can only provide you a solution that will export images with ExportToHTML. 

I have logged this feature in our Public Issue Tracking System - PITS. You can track its progress and add your vote/comment for it on the following link - PITS Feature.

I have also updated your Telerik points for the good suggestion.

Should you have other questions, I would be glad to assist.

All the best,
