RadGridView is a really good Grid but the edit experience is terrible...

I try to explain my problems with a check box column.

1) I click it, nothing happens but perhaps now the cell is selected, the style is a little bit changed

2) I click a second time, nothing. But perhaps now the style of checkbox is changed, now it is enabled

3) I click a third time, good now the check is box checked but the Item source value is not change, we are waiting for a magical "CellEditedEndEvent", why???

4) I press the enter key, now the value is really changed.

Now suppose that a user must check 100/200 items/day, it is the work of this user, why we are asking to user "please click 500/1000 time per days instead please..."

Hello Marcello,

I'm sorry to hear that you're displeased with the GridViewCheckBoxColumn's default editing behavior. Could you please have a look at the following article which demonstrates two approaches on how to change the number of times the checkboxes need to be clicked to update the underlying value?

Do let me know whether you find this resource helpful. If I can be of any further assistance, don't hesitate to get back to me.

Hello Dilyan,

Thanks very much, this can solve a big part of my problems (I'm curious, why this is not the default??)

But the point 4 is not solved, how to force the update of ItemSource happens on same single click?

Hello Marcello,

This is the column's initial design and the AutoSelectOnEdit and EditTriggers properties were introduced later on in the life of the RadGridView control. Modifying this behavior would have proven to be a breaking change for some of our clients and that is why the default values stayed as is.

The fourth point of your requirement can not be achieved with the first approach from the article as it bypasses RadGridView's validation mechanism. If you find suitable, you can use the second approach and define a normal GridViewDataColumn with a custom CellTemplate, containing a CheckBox bound to the underlying property.

I hope this clarifies things for you. If you have any other questions, don't hesitate to ask.
