QueryCanMergeCells

[Jason Allen]

Hi

I am experiencing problems with cell merging in a virtual grid control.

I initialise the grid control with grid.Model.MergeCellsMode = OnDemandCalculation|MergeRowsInColumn;

I want all columns to be queried for cell merge. The only way I found to achieve this was to set the initial column count to the max number of columns I need and iterate the ColStyles collection setting MergeCell = RowsInColumn.

The initial display of data works correctly. However, as I change the data in the grid, the QueryCanMergeCells events is repeatedly fired, but not for all cells in view. The result is that some cells are not correctly merged.

QueryCellInfo is correctly fired for all cells so why not QueryCanMergeCells?

How can I force the grid to fire the QueryCanMergeCells event for all visible cells?

Best Regards
Jason

Does setting

grid.TableStyle.MergeCell = RowsInColumn 

make it unnecessary to loop through the ColStyles in your code?

Yes it does, it also appears to fix the event problem. Thank you very much!
