Originally created by @AndreZinner on GitHub (Jun 28, 2022).

in version 3.18.x the normal behaviour for a DataGrid in FilterMode.Simple was:
rows are displayed, if the text entered by the user is contained within the value of the property of the corresponding column.

in version 3.19.0 (and later) the text entered by the user must be equal to make the row appear in the resulting list.

Is there any new property introduced to the datagrid hat I can set, to get back the old behaviour?
(which is of course the normal way a user expects a column filtering feature)

Yes, on your demo it does.

But in my app the behaviour changes as soon as I go from 3.18.x to 3.19.0. (without any further changes!).

When I use FilterMode.SimpleWithMenu I can observe, that in 3.18.x the default filter condition is "CONTAINS".
When I use 3.19.0 the grid and it is displayed on page loading for a fraction of a second I can see "A" (=filter condion "contains") on the filter button. Then the condition changes to "=" (= filter condition "is equal").

So you definitly changed some defaults, probably by introducing the enum filter.

Further information: the column the working as expected when I set FilterOperator="FilterOperator.Contains".
So I suppose that this was the default in 3.18.x.
(But it is of course very anoying when I must add that to all my columns in all my grid ....)

And in 3.19.x (at least for some value types) the default changed to FilterOperator.Equals.
