XamDatagrid: LoadCustomizations() Crash with groupby
posted

Hello,

I am using XamDatagrid 19.1.244 and have fields that are defined in XAML and additional ones in code behind. When group the grid by one or more fields and save the customerizations it crashes on Load().

The message is: "Der Index lag außerhalb des Bereichs. Er darf nicht negativ und kleiner als die Sammlung sein.
Parametername: index" = index out of range...

Please advice steps to troubleshoot this.

Thanks

Niko

    Hello,

    I have been looking into your question and as the exceptions says, you are trying to case a Record to a DataRecord, while it is a GroupByRecord. The GroupByRecord does not expose the Cells collection and this is why the exception is thrown.
    When the XamDataGrid is grouped, the Records collection exposes GroupBy record. You should check if the Record is GroupBy or DataRecord and to set field's value only if it's DataRecord in order for this code to work.

    I have created a small sample trying to reproduce the described behavior. In the InitializeRecord befor setting values to te unbound field that is defined in code-behind I'm cheking if it is a DataRecord.

    private void MyGrid_InitializeRecord(object sender, Infragistics.Windows.DataPresenter.Events.InitializeRecordEventArgs e)
        {
            if(e.Record.RecordType == RecordType.DataRecord)
            {
                int index = ((Infragistics.Windows.DataPresenter.DataRecord)e.Record).Index + 1;
                ((Infragistics.Windows.DataPresenter.DataRecord)e.Record).Cells[2].Value = index;
            }     
                                 
        }

    Attached you will find my sample for your reference. Please test it on your side and let me know how it behaves. If this is not an accurate demonstration of what you are trying to achieve please feel free to modify it and send it back to me along with steps to reproduce. Alternatively, if the behavior cannot be replicated please feel free to provide your own sample. Remove any external dependencies and code that is not directly related to the issue, zip your application and attach in in this case.

    Having a working sample on my side, which I can debug, is going to be very helpful in finding the root cause of this behavior.

    Thank you for your cooperation.

    Looking forward to hearing from you.
