If your data contains uint, long or any numeric type different than Int32 or Decimal, the searching doesn't work.

 

When format cell is copying from Excell, only the formatted value is passed into the RadGridView.

 

 

When the bound to the RadGridView objects implement the IDataErrorInfo interface and an invalid cell is scrolled out of the viewport, the corresponding row becomes valid.

When there are 1000 (reproduce with 500) distinct values in the Popup filter and we try to select all of them it took 15 seconds and more when using ICustomPropertyProvider.

The GridViewMultiColumnComboBoxColumn of RadGridView allows you to enter the edit mode of the corresponding cells even when the IsReadOnly or IsReadOnlyBinding properties of the column are set to True. 

This is also reproducible when RadGridView.IsReadOnly property is set to True

This is reproducible only when the SelectionMode is set to Multiple.

When navigating through the cells with the left/right arrow keys, when the last column is reached normally the focus stays on that cell. However, when there are invisible columns on the left/right of the last visible one, the focus moves away from the grid.

As a workaround you can handle the PreviewKeyDown event of the RadGridView when the CurrentColumn is the last visible one.

My requirement is to give certain rows in the GridView a background color that is read from the database (so it's not a fixed list of colors). I use the RowStyle with a binding to the Background property. When the bound property is null, I fall back on the Transparent color.

This transparent background in combination with a GridViewComboBoxColumn sometimes causes rows to "stick" to the top or bottom of the grid. To simulate this, a ComboBox in the grid must be opened, then you need to scroll up or down until the field is outside the viewport. In some cases, the row sticks to the top or the bottom. After inspecting the Visual Tree, it appears that the row is still part of the Visual Tree, even though it is outside the viewport. I have attached a video and a sample project where you can see and test this behavior.

The content of the cell is set from .LoadContent() method and is returned from the CreateCellElement method of the column. 

One possible scenario for a fix is to change that behavior and apply directly the template as WPF DataGrid does. However, this is a huge breaking change with CreateCellElement method is widely used. The second approach is to leave the code as it is right now, return the element from method of DataTemplate and set the ContentTemplate property of the cell to that DataTemplate. This will cause the content to be loaded twice. Which will degrade the  

So, as it turns out the solution is either to introduce breaking change or degrade the performance. Both of them are against our believes and efforts to improve the controls. 

Our suggestion is to use a workaround -  setting triggers directly to the style. We do hope you understand our concerns. 

Setting GridViewCell content template by Style is not working with R1 2019. 

When all columns are readonly, the NewRowPosition is Bottom, a new row is added through the UI and the Tab key is pressed, an InvalidOperationException is thrown.

 

When the ItemsSource of the RadGridView is reset, disctinct values remain checked in the Filtering Popup. 

For a workaround, check the attached project. 

This behavior is observed when Office2013 theme is applied. 

 Group rows which are not present in the view are not visualized when the window is maximized.

A possible solution here is to set the GroupRenderMode property to Flat.

Expose a collection which holds the region of the currently selected cells.

for radgridview,if CanUserFreezeColumns="True" ,
when adjust the FreezeColumnsResizer to the right,and then resize the left colum'width,
if exceed the visual area,these exceed area's column will disappear!
for example,the data virtualization sample for the radgridview,if set the FreezeColumnsResizer
to the 'Unit_Price' column behind,then adjust the 'Product_ID' column width to exceed the visual area,
at last by scroll,you can't find the exceed visual area columns

Expose a SearchText property so that search as you type can be achieved through a custom TextBox instead of the GridViewSearchPanel.
