I have a function that resizes a grid page size when the page has loaded,
I have used the "OnClientLoad" event of the main page splitter to fire this function.
However when the function uses an ajax request i get the following error:
Error this_tooltips.length is null or not an object
(I have attached a screen Shot)
This is the code:
h1 = $find(
"<%= RadSplitter5.ClientID %>"
"<%= RadAjaxManager1.ClientID %>"
Left(e.Argument, 13) =
'Set Radgrid1 page size
(Right(e.Argument, Len(e.Argument) - 13))
= (pHeight - 110) / 30
rows >= 1
The Problem does not occur on initial load of the page, It seems to occur on a re-query of the Grid? But not all the time.
I was wondering if it was related to mouse position on the grid as i have tooltips coded to the grid's ItemDataBound Event, The tooltips were in the ItemCreated Event but i moved them to see if it would cure the problem.
If anyone could shed any light on this it would be most appriciated.
