Setting column width causing performance issue
posted

I have a Grid that has a large number of columns, one for each day. There could be 100s of columns in this DataTable for those many days.  After the DataTable is bound to the Grid, I am setting the width of each column as you see in the code snapshot. 

 

I find it hard to understand why setting the Width is so expensive. It takes 24.86 compared to setting the Format on the next line which take only 0.003 . I found it hard to  believe at first but repeated runs of C# profiler confirmed this inefficiency. 

Is there a way I can avoid setting the column width one at a time. Is there Grid level or row level setting? Or some other suggestion?

Thanks!

I am on version 7.3

    Hi,

    Do you have the latest service release? I think there might have been some optimizations made in this area in a recent service release.

    Also, if you are looping through the grid columns and setting lots of properties on a lot of different columns, it's a good idea to try to make this code as efficient as possible. I recommend that you do this in the InitializeLayout event of the grid, if you can.

    Also, you should use the BeginUpdate/EndUpdate methods on the grid. There is further discussion of this technique in the WinGrid Performance Guide.
