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.
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
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.
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 applying Grouping and RowHeight to the DataGrid and expand the row details, the following happens -> The DataGrid in the RowDetails only appears for alternate rows.
In addition the RowHeight does not apply to the Grouping Row.
Workaround:
Remove the RowHeight from the DataGrid and set the CellContentStyle property to the columns and set the TextMargin to the DataGridTextCellStyle, and ButtonMargin to the DataGridToggleRowDetailsCellStyle. Here is an example when setting them to 0:
<telerik:DataGridTextCellStyle x:Key="cellStyle"
TextMargin="0"/>
<telerik:DataGridToggleRowDetailsCellStyle x:Key="toggleStyle"
ButtonMargin="0"/>
<telerik:RadDataGrid.Columns>
<telerik:DataGridToggleRowDetailsColumn CellContentStyle="{StaticResource toggleStyle}"
IsFrozen="True"/>
<telerik:DataGridTextColumn PropertyName="Country"
CellContentStyle="{StaticResource cellStyle}"
IsFrozen="True"
CanUserReorder="False" />
<telerik:DataGridTextColumn PropertyName="Capital"
CellContentStyle="{StaticResource cellStyle}" />
</telerik:RadDataGrid.Columns>
A work-around is to remove the columns one by one:
for (int i = this.dataGrid.Columns.Count - 1; i >= 0; i--)
{
this.dataGrid.Columns.RemoveAt(i);
}
Navigating to a DataGrid that is placed on third page first time the control displays when navigating to the third page. When navigating back to the second page and then go back to the third page the control do not display.
On net 8 works as expected, the issue happens on net 9 and singleton approach is used.
