Currently I'm facing a RadGrid issue/bug where I'm unable to bring up the correct Edit input row.
Only happen if holding down your mouse while you click on a cell and drag away the mouse elsewhere and let go of the mouse click.

I have created an example scenario. The code is down below.
The first column is a GridTemplateColumn which contains a RadComboBox.
The second column is a GridBoundColumn.

RadGrid Settings:
<ClientSettings>
<Selecting AllowRowSelect="False" CellSelectionMode="SingleCell" />
<ClientEvents OnCellSelected="onCellSelected" />
</ClientSettings>
<MasterTableView EditMode="Batch">
<BatchEditingSettings EditType="Cell" />

Here is a scenario to reproduce the symptoms that I'm facing.
* Click on a GridTemplateColumn column cell which brings up the correct EditItemTemplate row and user can enter their input, etc.
* Click on a different GridTemplateColumn column cell and hold down your mouse while you click and drag away the mouse elsewhere and let go of the mouse click.
* Radgrid will highlight the correct GridTemplateColumn column cell however the previous EditItemTemplate row is still displays in edit mode.
* Repeat same step on to a different column.

~Any help would be greatly appreciated.
