GDBG: Refresh data

[Amy Patterson]

I have a data bound grid where I initalize the row and column settings in the code then I attach it to a data source that is loaded from a SQL Query.

I occasionally refresh the data table with new data from SQL. How can I refresh the grid without having to reset all of my column and row settings?

The data is stored in a dataset and is refilled from SQL at run time.

Hi Amy,

Use the Grid.Refresh or Grid.Invalidate method to redraw the whole grid. If you want to repaint the particular cell/region, you can call Grid.Model.RefreshRange passing in a range of cells to limit the painting to something other than the whole grid.

When I use any of these it gets rid of my column formatting. I am hiding some columns and setting the formatting of others. Doing a refresh updates the data but deletes the column formatting. I am trying to avoid having to set the formatting every time that I do a refresh of the data.

The reason for this is that I have a column of buttons and every time I reformat the column, after a button was pressed, it does not seem to clear out the event stuff properly and it is calling the button event three times for every row in the table.
