I also turned off all tooltips in the style of the grid at the grid cell. Here is some code
Disabling in grid
<telerik:RadGridView x:Name="grdRreList" Grid.Row="1" ItemsSource="{Binding Path=CurrentClient.ResponsibleReportingEntityList, Mode=TwoWay, NotifyOnValidationError=False, ValidatesOnExceptions=False}"
AutoGenerateColumns="False"
Disabling in GridCell
<telerik:GridViewDataColumn ValidatesOnDataErrors="None" CellStyle="{StaticResource GridViewCellStyle}" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}"
DataMemberBinding="{Binding Path=SignedProofDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, NotifyOnValidationError=False, ValidatesOnExceptions=False}"
DataFormatString="d" Header="SIGNED PROOF DATE" MinWidth="160" >
and disabling in styles

The validation ToolTip you are referring to is the default one of the TextBox ( TextBox is the editing element of GridViewDataColumn).
In order to remove it, you can try to handle the CellValidated event and set Handled property to "True". Please check the following code snippet for a reference:
private void MyGridView_CellValidated(object sender, GridViewCellValidatedEventArgs e) { e.Handled = true; }I hope this helps.
