Hi,

I have a grid that is bound to a DataTable. The structure of the DataTable varies at runtime so I cannot set the columns at design time (AutoGenerateColumns is set to true). When a column of the DataTable is of type System.Byte[] the grid shows "System.Byte[]" and I would like it to show an image instead. I am guessing I should be using a DataTemplate for this type but I am unsure of how to do this with the GridView, can you please help or point me to the relevant resource?

Cheers,
Jose

Hi Yavor,

Thank you for the link. I will definitely use the converter in that blog post but my scenario is slightly different because I have AutoGenerateColumns=true whereas the example in the blog post has AutoGenerateColumns=false.

My question is: Does the GridView, when bound to a DataTable, allows replacing the CellTemplate for a column depending on the type stored in the column of the DataTable?

Cheers,
Jose

Hello Jose Simas,

 To achieve more control over the column generation, you need to handle the AutoGeneratingColumn event and assign the DataTemplate where necessary.
