How to export the images that are loaded inside the GridTemplateColumn to PDF document?

SfDataGrid control exports the data to PDF using Syncfusion PDF Component. Generally, you can export the images to PDF document when the images are loaded inside the GridImageColumn.

You can also load the image by using GridTemplateColumn. The following screenshot illustrates the GridTemplateColumn “Pass or Fail” loaded with the corresponding images that are defined as a DataTemplate of that column.

You cannot export the images to PDF document when it is loaded inside the GridTemplateColumn.

In that case, you can achieve it by customizing and assigning the same images to the background of PDFGridCell while exporting, with the help of CellsExportingEventHandler delegate of PdfExportingOptions. Refer to the following code example.

C#

In the above code example, GridCellPdfExporting event handler is assigned to the CellsExportingEventHandler delegate and it is invoked while exporting each cell to PDF. Here, you can handle and customize each PdfGridCell while exporting, and GridCellPdfExportingEvent contains the following argument as a parameter.

1. Sender: The sender is SfDataGrid.
2. GridCellPdfExportingEventArgs: It contains a set of properties that are used to customize the cell to PDF and some of them are as follows:

• CellType: You can use this property to check the type of the exported cell.
• CellValue: It contains the actual value that is to be exported to PDF.
• ColumnName: Specifies the column name of the exporting cell.
• PdfGridCell: Specifies the PdfGridCell to be exported and you can customize the style, background, foreground and alignment of a particular cell.

Here, you can access the images from the resource file and you can set them to the background of PdfGridCell style as illustrated in the following code example.
