Data Grid's DataGridCsvExporter problem

Hi there,

We just found the problem for DataGridCsvExporter if the datagrid is binding to the BindingList. It will always lose the first row when exportmode is set to DataGridExportMode.All,

Here are the code:

        DataGridCsvExporter exporter = new DataGridCsvExporter();
        exporter.Delimiter = "\t";
        exporter.ExportMode = DataGridExportMode.All;
        exporter.IsQuotingEnabled = false;
        exporter.IsColumnHeaderExported = true;
        string clipboardVal =  exporter.WriteString(dataGrid);

The first row of data is missing from exporter.WriteString(dataGrid). But if you call exporter.WriteString(dataGrid) twice/2nd time then it will have all the data.

Thanks, Gordon

Hello Gordon

I have not been able to reproduce this problem. When exporting a DataGrid using a BindingList and the exporter settings that you posted, I am seeing all the data (and the column headers) in the exported string. Looking through the code, I can not see how it would be possible to miss the first row of data. In ExportMode = All, it simply gets the BindingList itself, and iterates it to generate the csv string. Is there any more info you can think of related to this issue?

Hi Jason,

If the class in the Bindinglist has string property, then you can reproduce it

1) Unzip and run the attached project

2) click on MoreProblem button

3) Click on insert button a few times

4) click on Copy button

5) then open notepad.exe

6) paste it to the notepad window, you will see the first line of the first 2 columns are missing

7) repeat 4-6, then everything is fine.

Hello Gordon

Thanks for the repro project. This bug will be resolved in the next nightly build.
