Currently it is not possible to insert custom worksheets (for example notes or a cover page) when exporting via ExportToExcelML

Improve the filtering by date time column by adding properties that enable choosing whether to include time part and seconds part

create a filter on the "Status" column before clicking Save and Load?

Invalid filter expression. ---> Telerik.Data.Expressions.InvalidExpressionException: Cannot perform '=' operation on WindowsFormsApplication1.EmployeeStatus and System.String.

Clearing and refreshing the rows in a data table bound to a RadComboBoxColumn causes problems in the RadGridView. The column's drop-down stops working and in some cases the entire grid has become unresponsive.

Selecting datasource throws exception, then crashes VS

1) When the grid first loads, the top-left most cell is automatically selected. Before clicking anywhere within the grid view, if you hold SHIFT and click the cell to the right of the selected, the following exception is thrown.
2) You can get around the above exception by clicking a different cell in the grid view before performing a SHIFT select or CTRL+C operation is performed against the grid view. If you select a different cell, and then perform a SHIFT selection to a cell in a different column, you will experience the "An entry with the same key already exists." exception

The used RadGridView BindingSource is bind to another instance of BindingSource in this case

I use a BindingList to bind our data to grid. But when I set to this list two classes with common interface but different implementation (override of baseclass virtual property), an data exception error is thrown. The same code works fine in previous versions.

“Missing data after apply Object-Relational filtering operation” as in the attached, also capture case simulation in video file to illustrate how the case happen to support your investigation. Scenario case: ·         Expand Parent Data 2 à will see child data level (child data 2.1.1, child data 2.1.2, child data 2.1.3) ·         Filter child data that contains value = input “2.1.4” (mismatch case filter)·         Current Result : Not show all 3 child data and cannot get it back to display again   In this case, normally how the component handle this “not found filtering result” case, is it normal to display result like this? If so please help recommend how we can get 3 child data back for doing any further process.

The issue is reproduced when the columns for GridViewTemplate are added last in the end after the all hierarchy settings: relations, templates

I still have the performance problem. I have attached the same project extende by a new button/(function to create a new group with one root entry and 100 sub-entries. This takes a while due to the log of the data context, but what really takes me off is the performance of the grid when opening this root entry. On my machine (i5, 4GB ram) it takes about 5-6 seconds for the sub-structure to open. The zip also contains an old version of the program and in the bin/debug folder you can find the "RadTest.exe" (as opposed to the RadTest2.exe), wich will open the sub-structure in no time.
So - there must be something wrong with my way of working the grid.

To reproduce: Run the program, click the "Generate" Button and enter a name for the new group. This will create 101 new entries (1 root, 100 subs), taking about 15-20 secs (which is ok, as I said above).
Then open the "RootEntry" within the group -> takes 5-6 seconds. When the subentries are visible, scrolling the grid vertically is really slow as well.

I have a form with a RadGridView that's bound to an list of Custom Objects. Each custom object has a property that is also a list of custom objects of a different class. I added a child template to the main grid for this property and created a relation between the two. Everything displays nicely and I can add new rows to the main grid. However, when I attempt to add a new row to one of the child grids, the row does not get added.

Gridview doesn't update binding source current position after sorting and selecting row with the same offset position from the begining

I am getting errors at runtime when I try to see the 3rd level in the hyerarchy.

i use a radgridview whits does not allow edit. i press control-v at a cell and it pastes to the cellvalue the last copied to clipboard text.
is there a way to do that only if the grid allows edit?

Escaping special symbols in filter expression when used IsEqualTo operator

Setting the FormatString of a column in the child template does not seem to take effect.

Workaround: to avoid this behavior iterate the Rows collection of the master template and invoke their HasChildRows() method. which will sync up their parent

Allow setting the height of the group panel in design time:
 - by setting its height property
 - by using mouse cursor via property builder

Add a TextAlignment property of GridViewSummaryItem.
