microsoft.reportviewer problem

Question

I list records between two related tables with microsoft.reportviwer. Many records come from the database to 1, but I cannot bring the images. On the side where there are many, the path of the image is kept in a field, and there is also an image folder, this path shows that place. pictures are not coming

Answer 1

To resolve the issue of images not displaying in Microsoft ReportViewer, ensure that the image paths stored in the database are correctly mapped to the image control in the report. Check that the image paths are accessible and correctly formatted. Additionally, verify that the image folder location is accessible from the report viewer's context.

You can use expressions in the image control properties to dynamically set the image path based on the database field value. Make sure the image path is relative to the report or provide the full URL if necessary.

By verifying the image paths, ensuring accessibility, and correctly setting the image control properties, you should be able to display images successfully in Microsoft ReportViewer.

Answer 2

It seems like you’re trying to display images from a database in your ReportViewer control. Here are some steps you can follow:

1. Ensure that the image data is correctly stored in your database. The data type for storing the image should be System.Byte[]1.

2. In your RDLC report, set the image property source to ‘Database’ and the value to the dataset field that contains the byte array of the image1.

3. In your code-behind file, you need to enable external images and refresh the report viewer after setting the data source1. Here’s an example:

ReportViewer1.LocalReport.EnableExternalImages = true;
ReportDataSource rds = new ReportDataSource("DataSet1", pcal);
this.ReportViewer1.LocalReport.DataSources.Add(rds);
this.ReportViewer1.LocalReport.Refresh();

 

1. If your images are stored as paths in the database and the actual images are in a folder, you can use an HTTP Handler to read the image from the database and write it to the response stream2. Then you can set the image control in your report to use the URL as the source2.

Please replace the placeholders with your actual data. If you continue to have issues, please provide more details about your implementation and I’ll be glad to help further.

Thanks

I am looking for a code to list the expression stored in the imagepath variable in the image table from the physical image file folder according to the imageid relationship from the product id to the image table linked to it in multiple related tables.
