Summary: DataGridView poor performance for moderate number of
records (1000) makes it unusable
Classification: Mono
Product: Mono: Class Libraries
Version: 2.4.x
Platform: x86-64
OS/Version: openSUSE 11.1
Status: NEW
Severity: Major
Priority: P5 - None
Component: Windows.Forms
AssignedTo: [email protected]
ReportedBy: [email protected]

Found By: Community User
Description of Problem:
The DataGridView have a unusable performance. That is some seconds for 15
records and near 20 minutes for 1000 records. After the data is loaded
performance seems acceptable.
While calculating, the cpu goes 100% for the application and the OpenSuse 11.1
start bar is locked (but alt+tab works)
Steps to reproduce the problem:
1.
Fill a DataTable with 20 fields and 1000 records for example.
2.
Assign the DataTable to the DataSource property of DataGridView. DataGridView
should be visible, of course.
Actual Results:
About 20 minutes of waiting, then, the result is shown.
Expected Results:
Just for small comparison the Windows .Net framework takes less thank 1 second
for 1000 records and some seconds (not one minute) for one million records.
How often does this happen?
Allways
