Excel-like pop-up location is not scaled properly on High DPI.

In themes ‘TelerikMetro’ & ‘TelerikMetroBlue’ when you group columns in GridView there are arrows to expand the groups, they are obviously larger than they should be

On the second opening, it corrects:

Clicking the filter icon will reopen the filter popup. In the following scenario, the filter pop-up is open. If we click the filter icon while the filter popup is open, it will close it and reopen it. This leaves the end user with flashing behavior. The filter icon should close the filter popup if it is open.

Steps to recreate:

• click on the button on the top row
• press the down key on the keyboard
• Press Space key to select new button, the button on the top row is clicked

 After apply some filters, the treeview will not update automatically to tick or untick values that were included/excluded by the filter.

In this scenario, we have custom RadListFilterPopup. There could be a scenario in which we don't need the default menu items( input textbox, list of distinct values, buttons). If we override the CreateListFilterMenuItems() method and don't call the base code, NullReferenceException will be thrown in the Dispose() method.

In the current scenario, when clicking on the checkbox inside a GridViewCheckBoxColumn, the CellBeginEdit event will be called. If we cancel the event by setting the Cancel property to true, the CellBeginEdit will be called twice.

In this case, we have a GridViewHyperlinkColumn in which we have a cell with an empty string or null value. Exporting the control in XLSX format leads to an exception.

In this scenario, the MultiSelect option of the control is enabled. If we click and hold the mouse to select multiple cells and go over a merged cell, NullReferenceException is thrown.

The EnableHotTracking property works only in the first level hierarchy. The lower levels still get highlighted.

In the following scenario, we have enabled the pager functionality of the control. If we move to a different page and then set the DataSource to Null, the page index will not be reset. 

The search functionality is inconsistent in Unbound Mode. Typing a word highlights all rows that contain that word or string, as expected. However, if the cursor is moved and additional characters are typed at the beginning of the search box, no results are returned, even if matching rows exist that contain the updated string combination.

The same behavior is not observed in bound mode.

This behavior is related to how the control is measured while using the MS Form. In the given scenario, the control has many columns, and some of them are pinned. Moving to the last column and typing in the filter cell will filter the rows in the column. However, when filtering, if the row number is less than the viewport, the vertical scrollbar will disappear as it is not needed anymore, and the filter editor will be placed in the wrong column. This will mess with the filter cell editor. 

This behavior is observed when referencing 2025.1.211 version of Telerik UI for WinForms controls.

 

The CellSpacing property value is not taken into account. This property has different value in different themes.

System.ArgumentException: 'An item with the same key has already been added.' when the data source contains DateTime with the same hour, minute, and seconds part (only milliseconds are different):
