Hi,

I'm not able to implement a working TooltipTemplateSelector for cells with property IsEnabled=false.

The TooltipTemplateSelector will be instantiated correctly, but the SelectTemplate method will never be called.

When IsEnabled is set to true, then TooltipTemplateSelector works as expected.

In my eyes this is a bug and should be fixed.

Regards
Harald

Hi Herald, 
You can show the tooltip for disabled cells by using CurrentCellActivating event instead of disabling the cells. 
this.AssociatedObject.CurrentCellActivating += AssociatedObject_CurrentCellActivating; 
 
private void AssociatedObject_CurrentCellActivating(object sender, CurrentCellActivatingEventArgs e) 
{ 
    if (this.AssociatedObject.Columns[e.CurrentRowColumnIndex.ColumnIndex].MappingName == "Value") 
    { 
        var rowIndex = e.CurrentRowColumnIndex.RowIndex; 
        var recordIndex = this.AssociatedObject.ResolveToRecordIndex(rowIndex); 
        var record = this.AssociatedObject.View.Records[recordIndex].Data as DataItem; 
 
        if (record.ItemType == 2) 
            e.Cancel = true; 
    } 
}

Hi Jai,

thank you for the solution.

It works as expected, but in my opinion Tooltips should also be shown on "disabled" cells (without this complex effort).
Maybe you can redirect my wish to your developers.

Hi Harald, 
We regret to inform you that, we cannot showing a tooltip for disabled cells in SfDataGrid. This is the default behavior. However, as we said in our last update, you can use the CurrrentCellActivating event to achieve your requirement.
