To reproduce this:

1. Set the ShowToolTipOnTrimmedText property of RadGridView to True.
2. Hover a cell with trimmed text.
3. Before the tooltip shows, move the mouse quickly, outside of the RadGridView control.
4. Regardless of the fact that the mouse cursor is outside of the RadGridView control, the tooltip showing is not canceled and it shows after a second.

To resolve this, set the ShowToolTipOnTrimmedText of the gridview columns instead of the RadGridView control.

Users reported that the Text Search feature is misbehaving for certain columns in their grid.

We found that that if we take the Telerik example “DeferredSearching_WPF.sln", and change the "int" field+property to "long" , text search for a number indeed falls over.

Can you reproduce this?

Change the Default Selected Filter Operator:
https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-change-the-default-selected-filter-operator

This doesn't work for boolean columns, if the property "ShouldGenerateFieldFilterEditors" of the column is set to "True". 

Please see the attached example.

*** The fix for this issue will be available with the next LIB (version 2018.3.1217) expected on Monday, December 17.

• Open the GridView examples
• In the available examples, select "Selection and Usability | Row Details"
• Select a row in the grid view
• In the external Details Presenter, select : nothing is displayed in the bottom.
• You have to select another row and then come back to show the detail.

 

The fix for this issue will be available with the next LIB (version 2018.3.1217) expected on Monday, December 17.

Allow customizing the FieldFilterControl shown under the column header when the FilteringMode is set to FilterRow. Currently, you can customize this only via an implicit style or by looking into the gridview's visual tree in code. It would be useful if you can define a style per column.

A possible workaround is to show and hide the columns.

foreach (GridViewColumn col in TestGridView.Columns)
			{
				bool visibility = col.IsVisible;
				col.IsVisible = true;
				col.IsVisible = visibility;
			}

This behavior is reproducible when the SelectionUnit property of the RadGridView is set to "FullRow".
SelectedCells collection is not of the selected row updated when new columns are added runtime. For example, you have selected the first row which has 3 cells. Then you add 2 new columns. Now the row has 5 cells but the selected cells collection still have 3.

A possible workaround which can be used is to reset the SelectedItem property of the RadGridView.

var selectedItem = testGrid.SelectedItem;
testGrid.SelectedItem = null;
this.testGrid.Columns.Add(new GridViewDataColumn() { Header = "Value3", DataMemberBinding = new Binding("Value3"), Width = 100 });
this.testGrid.Columns.Add(CreateColumn("Value4", "Value4"));
testGrid.SelectedItem = selectedItem;

radGridView has a feature to provides a suggest and append feature.  Currently, there is the ability for the end user to inadvertently close this window.  Please provide the opportunity via a property to disable the ability to close the search window.  (currently, I am hooking the SearchPanelVisibilityChanged event, and forcing showSearchPanel = true at all times.

Scheduled for: 
The exposed property (SearchPanelCloseButtonVisibility) will be available with LIB (version 2018.3.1210) published on Monday, 10-th December, 2018.
