I have a report that has a PictureBox on it which I am using for an employee signature. I store the signature in the SQL server as a varbinary(max). The employee signature will be different for every report and is returned in the SqlDataSource for the report. I recently started getting a ""Parameter Not Valid"
exception when rendering the report as a pdf and had to reboot the IIS server to get the report to render again. I must either be doing something wrong or not using the best practice for this scenario. Here is how I am importing the bmp signature to the table in SQL server:
EmployeeSignature = (
Here is how I am rendering the report to pdf:
var irs =
Telerik.Reporting.Processing.ReportProcessor rp =
Telerik.Reporting.Processing.RenderingResult result = rp.RenderReport(
 contents = result.DocumentBytes;
+ id +
I think it is the signature block causing the issue but I could be wrong. Any suggestions as to how to properly add a bmp file to a report dynamically?
