I have a column of weights, but for some rows, the weight is unknown (not 0, but really unknown). I would like it to say "4 kg" in the cell that belongs to a row with a weight that is 4 kg, and "" (the empty string) in the cell that belongs to a row with an unknown weight.
This functionality exist with plain bindings (via TargetNullValue) for ordinary TextBoxes. Syncfusion SfDataGrid (a competitors alternative to RadGridView) supports this. I am fine with needing to do things different with Telerik controls, but surprised that such a simple feature is missing.
