How to show data cache ....

[Ken Lee]

Hi,
I using CellQueryInfo event show the data cache that get from the other data source stores in arraylist( but always the cell is activated can display the data), The grid owns many columns, the first column made data changed in CurrentCellAcceptChanged event , in the same time get the data from the other data source and stores in arraylists( many data wnats to show different cells). My question is how it can show the data on different cells in same time ?Have you any idea?

Hi Ken, you can use Virtual Grid for this purpose. And you can use QueryCellInfo Event to display datas from different datasources and by SaveCellInfo event to update changes into the datasource. For more details on Virtual Grid refer to the Documentation/EssentialGrid/Tutorials/VirtualGrid Regards, Madhan.

Hi Ken, You have to use unbound Columns to display the values from the other datasources. Kindly refer to the Sample code for details. And you can use QueryCelloInfo Event for displaying the values in columns. When you want to show a new unbound column, then you have to call grid.RefreshRange to force the grid to redraw the particular cell. Regards, Madhan.
