I'm using UltraGrid with 20000 columns.
Sample Attached.
Is there another solution to improve this.
I can't think of a use case where the user would be presented with a grid containing 20,000 columns in one band. If you could shed some light on your application requirements and why you would have that many columns in one band, we might be able to help recommend a different solution.
The only thing I saw that might get you a performance boost is in the UltraDataSource.CellDataRequested handler, where you are concatenating the column key and row index to create a data key. Concatenating strings in this manner is inefficient as it causes heap fragmentation - in cases like this you should use a StringBuilder instead.
You might be mistaken about what I want to say.
I do not want to improve performance of CellDataRequested.Handler.
Even if CellDataRequested.Handler code is eliminated, it still takes 45 seconds to load up all UI.
What I want to do is to shorten the time to load up all UI.
Is there any solution to this problem?
Any suggestion and solution would be appreciated.
