GridView VirtualItemCount

[ALED]

Dear All,

I need a radgridview with PageSize = 20; which i want fill datasource by pagesize and current page index changed,

Ex: in Database i have record 100, so in my radgrid datasource i will fill with VirtualItemRecordCout = 100, which will generate 5 page, and fill page 1 only 20 rows from database rownum selection, and when i changed my radgrid index to page 2, i will fill my datasource from rownum 20 till 40 from my record nums in database selection.

in ASP telerik radgridview have property VirtualItemCount, how about in WinForms ? i really need cause i have lazy record, and its so long if i much select all,

I need your great solution.

Thanks.

Hello Aled,

Thank you for writing back.

You can use the RowCount and ColumnCount properties to set the desired(total) rows/columns number. In addition, the data is not loaded at once. The CellValueNeeded event will be fired only for the currently visible cells. For example, if the paging is enabled only the first page will be loaded. Then if the user selects another page the event will be fired again and you need to pass the data of the second page. The event arguments are containing the current cell index and based on this you need to pass the value. Another example for this is available here: Populating with Data.

I hope that you find this information useful.
