I have used the NestedView several times but this is the first time I see this error.
I have a RadChar and a RadGrid in the nested and when I click on any row at first time, then the nested doesn't open, but after, I can open all nested.

I tried change de databind of radchart on OnItemCommand and but not work
If I remove de ajax it works prefectly
The subRadGrid created in the nested work, and do databind in the OnItemDataBound correctly

Why I lost first click?

if (e.Item is GridNestedViewItem)

#endregion

// Extraemos la información de DataKeyValue desde la grid principal
