Binding to business object - Bug?

[Administrator]

Hi,

I have a GGC which is bound to a business object. The business object allows me to add more columns during runtime.

I have attached a sample application. When I click on the "Add Column" button a new column is added to the grid (it seems everything is fine). Now when I change a cell value before I click on the "Add Column" button, the grid freezes followed by a strange exception. It seems the painting of the grid gets stuck.

It would be great if someone can take a look at that issue. Thanks in advance.

Cheers,
Chris

Hi Chris,

You can handle the SourceListRecordChanging event and set e.Cancel = true when e.TableListChangedEventArgs is null. Andalso you need to set the Engine.UseOldListChangedHandler = true. Here is a code snippet.

gridGroupingControl1.Engine.UseOldListChangedHandler = true;
gridGroupingControl1.SourceListRecordChanging += new Syncfusion.Grouping.RecordChangedEventHandler(gridGroupingControl1_SourceListRecordChanging);

void gridGroupingControl1_SourceListRecordChanging(object sender, Syncfusion.Grouping.RecordChangedEventArgs e)
{
if (e.TableListChangedEventArgs == null)
e.Cancel = true;
}

Please refer to the modified sample for implementation.
