When using ImageButton inside a CellTemplate, the image does not display initially. When you resize the window image is displayed. 

 

Workaround:

Use Image instead of ImageButton

 

When DataGrid is grouped and applying filtering, aggregates footer appears in the cells

expand a row and collapse it. Or expand a few rows, scroll around a bit, and then collapse one. You can get into some weird situations. Gray background over the group, row background and alternate styles are reset. 

Some data is missing from the UI when grouping is applied and then filter the data. 

If you ungroup, the items are displayed.

When entering a cell in edit mode its value is displayed on the next cell and the cell editor template uses MaskedEntry.

Starting with v10, all groups except the last, get a blank, empty row.

If you toggle off the grouping, the empty rows go away, but once you put the grouping on, these empty rows show up again.

Keep the data grouped, make the window a bit smaller so you have a decent amount of rows to scroll through, and using your mouse wheel, scroll up and down quickly. Eventually you'll notice that the grid will start to bounce a bit. For example, you'll scroll down and then without scrolling the mouse wheel up at all, it'll jump back up a few rows on its own.

NullReferenceException when entering the cell in edit mode, then refreshing the data, then enter the cell in edit mode and pressing the Enter key

Provide a RowStyleSelector property to the DataGrid control.

Begin editing the first cell firs column
Without closing the cell editor, scroll down to the last cell, the first cell should exit the viewport.
Start editing the last cell.
Scroll back up to the first cell

The content inside the first cell is missing.

The content should be there.

 I need to change the size of the DataGrid scrollbars to be wider and customize their color.

Provide an event that occurs when the content in the DataGrid is drawn. 

when loading same page without navigating to another page, there are some left instances of the DataGrid and the memory increase. 

There is a memory leak in DataGrid on Windows - when the DataGrid control is on the page, the page does not dispose when GC runs.

When a ComboBox editor is open in the DataGrid, one can use the arrow keys to go up and down the items of the combo in order to make a selection. When pressing Enter it is expected that the ComboBox gets closed and the DataGrid is still in edit mode for the same cell.

However, when the Enter is pressed - the ComboBox closes and the next row goes into edit mode - this behavior is erroneous.

I want to strikethrough the text in  the row based on a value. 

i checked and the column cell content style DataGridTextCellAppearance class does not expose such property.

When grouping in the DataGrid, add an option to align aggregates in group header based on the columns they are applicable

For example we have set RowHeight to 26 with GridLineThickness = 1, GridLinesVisibility = Horizontal, and RowBackgroundStyle and AlternateRowBackgroundStyle with BorderThickness = 0.

The first row is 26px, the middle rows are 25px and the last row is 24px. So it seems the grid lines are included in the calculation of the RowHeight. 

when a RadDataGrid has collapsed groups, trying to edit a row that comes after one of the collapsed groups (and a little bit of scrolling) is impossible, because the RadDataGrid scrolls back to the top.

If the DataGrid is placed inside a ScrollView, after upgrading to version 7.0 of the Telerik Maui tools the DataGrid is no longer visible on IOS.
