At design-time when you remove a RadGridView instance, its GridViewTemplate instances are not removed.

When RadTextBox is bound to a column (GridViewTextBoxColumn) in RadGridVIew it shows the current cell value. But once new row is added the value in the text box does not clear. Instead the last value stays. 

In case you add another row the value is being cleared.

There is a weird behaviour when the row is in edit mode and the user clicks consecutively in a different ComboBoxColumn. The drop-down pop-up is shown bun immediately disappear if the previous cell was also from ComboBoxColumn.

Excluding certain properties when layout is being saved

When loading layout in RadGridView, combo box columns lose their data-sources.

Include an easy way to clear selection and current row if the data source changed. Currently, it sets the first row as current and there is not a clear way to avoid this on every data source change.

This happens after setting in property builder the RadGridViews', DataSource (containing more than one table).

In the add new row element there is some cells€™ values, which are set through code (programmatically). 
However, if there is not at least one cell, which was manually edited (changed its value), the row cannot be committed.

In some cases Columns Group View has impropriate cells layout, mostly rendering two borders on one and the same side for some particular cells.

AutoSizeRows is not currently supported.

If there is an underling font in the grid, exported file cannot be opened from MS Excel.

When using textbox and grid bound to the same datasource, the grid should be updated automatically when the textbox loses focus

When using column groups view the last row is partially visible.

Issue addressed by RadGridView Q2 2010+ (version 2010.2.10.713+)

If there is conditional formatting it takes wrong settings for base cell colour.

RadGridView should be able to filter by enum values.

If in underling datasource there are more than one field, which do not allow null values, trying to set them in DefaultValueNeeded event leads to exception "Column [columnName] does not allow nulls"

Sort capabilities in column chooser form.

RadGridView remains in edit mode if the focus has been taken from RadToolStrip's item (for example: ButtonElement is clicked)
It is an issue in the obsolete RadToolStrip. Works as expected with RadCommandBar.

Set AutoSizeRows and WrapText to true.
Start resizing the form.
You will see that the cell size is wrong.
