VirtualGrid empty data

[Ben Hinton]

Hi,

I am using a virtual grid and I need to be able to show the correct columns when there is no data found. The columns are being created dynamically when there is data, so how do I create them when there isn''t data?

Many thanks.

If you are handling QueryColCount and QueryRowCount, the grid will use whatever values you set in e.Size.

So, when you want an empty grid, set a flag. In QueryColCount and QueryRowCount, when your flag is set, return the values you want to see. Also, in QueryCellInfo, if the flag is set, skip the normal code that you use there to access your data. Also, in SaveCellInfo, if the flag is set, just set e.Handled = true and return.

So, then you can make the grid show empty, by setting your flag, and calling grid.Refresh.
