[CLOSED] Paging Issue
Hi,
I am not yet upgraded to Ext.Net2.0. I am posted this issue in 2.x Premium Help.
Paging Issue.
Actually we have already developed one approach to get Data as in following code. While adding records to datatable we will verify some conditions and then modify that record to show properly GUI. Example if column value 2 it should show as II, or ii or two. This is just an example, in this way I have to modify the data in each column and then add to data column to show in the grid.
Please help me out how can I implement the paging to show first set (page size) of records quickly.
