Add a filter condition using the filter row of the RadGridView which filters all but one item and it will not be selected automatically.

IMPROVE. RadGridView - add the current selection and the new selection to the SelectionChanging event.

Please view the related project. The issue is valid when Sort API of Column object is used or sorting is added from SortDescriptors.Add method.

1. Create a new project with RadGridView
2. Setup hierarchy with two child views
3. Set the UseScrollbarsInHierarchy property to true
4. Run the project
5. Epxand a child view and try to resize its content, you will see a lot of white space which is not correct

1. Create a new project with RadGridView
2. Create an empty self-referencing data table
3. Set a self reference hierarchy by calling the AddSelfReference method
4. Add two rows in the table
5. Run the application and you will see that only one of the rows is visible.
DataTable table = new DataTable();
table.Columns.Add("Id", typeof(long));
table.Columns.Add("ParentId", typeof(long));
table.Columns.Add("Name", typeof(String));
gridView.DataSource = table;
gridView.Relations.AddSelfReference(this.gridView.MasterTemplate, "Id", "ParentId");
DataRow row = table.NewRow();
row["Id"] = 1;
row["ParentId"] = DBNull.Value;
row["Name"] = "Name1";
table.Rows.Add(row);
row = table.NewRow();
row["Id"] = 2;
row["ParentId"] = DBNull.Value;
row["Name"] = "Name2";
table.Rows.Add(row);
row = table.NewRow();
row["Id"] = 3;
row["ParentId"] = 2;
row["Name"] = "Name2";
table.Rows.Add(row);

1. Create a new project with RadGridView
2. Set SelectionMode to FullRowSelect and MultiSelect to true
3. Setup hierarchy
4. Expand a child view and select several rows with dragging
5. Click on the first selected row

When there are a lot of groups in the group panel there is a scrollbar. However sometimes it is convenient to resize this panel to allow all groups to be visible. Currently this is not possible.

FIX. RadGridView - GridViewCollectionChangingEventArgs in the FilterChanging event handler are incorrect.

The ConditionalFormatingObjectList of RadGridView's columns cannot be modified at design-time.

The problem exist for NotifyCollection - CollectionChanged event also. Filter events too.

When you set the value of unbound column in bound mode of RadGridView, the cell is not updated.

The CellClick event is fired when the mouse button is released after scrolling.

The GridSpinEditor of RadGridView changes its value automatically to its maximum.

I have a radform, drop a gridview on it, go into property builder for the gridview and add a textbox column, make the column read only, do not allow sorting, grouping, or adding, do not show the group panel or the column header row.  The top border is missing.

1. Create a new project with RadGridView
2. Set ColumnGroupsViewDefinition
3. Save the layout by calling the SaveLayout method
4. Load the layout by calling the LoadLayout method

GridViewSpreadExport does not export correctly more than one child templates from second level.

1. Create a new project with RadGridView
2. Create a new ColumnGroupsViewDefinition
3. Change the ViewDefinition property in the Designer.cs file before calling the EndInit method
4. Run the project

exception is thrown when the ListChanged event send ItemChanged notification before ItemAdded

1. Drag a RadGridView on a form.
2. Set the EnableFiltering and ShowHeaderCellButtons to true.
3. Fill the grid with data and run the project.
4. Open the filter popup and type something in the text field.
5. Press enter key and the popup will be closed without applying the filter.
