Solution 1 by
Sandeep Mewara is absolutely correct.
The client side functionality of
ASPxGridView
is provided by
ASPxClientGridView
as explained here
ASPxClientGridView Members[
^]
If the members given on this page are seen,
GetColumnsCount, GetPageCount and GetVisibleRowsOnPage
are available, but a method or property to get total rows of the
GridView
is not available as this data may not available on the client side, without querying the server side.
