Hi Timothy, I have a little problem with our solution. When I have a component with a textfield in the grid and I like to change the text it lost the focus because of the updateContainer. On my opinion in this case the onclick event of the row should not fire.
Do you have an idea how to do this? Jens Am 08.05.2014 um 04:13 schrieb Timothy Worman <[email protected]>: > Jens: > > I’ve implement a SingleSelectionAjaxGrid that extends AjaxGrid.
