Datarepeater delete 仅删除顶部记录

Question

I have a datarepeater and the following code ONLY deletes the FIRST record regardless of which one is selected. I am not entirely convinced this is the correct way to do it with a datarepeater but I could not find a better solution. I need to be able to select any record and delete it.

    //delete document
    private void cmdDeleteDoc_Click(object sender, EventArgs e)
    {

        if (this.dataRepeater1.CurrentItemIndex == 0)
        {

            //begin reset
            this.dataRepeater1.BeginResetItemTemplate();
            // Delete Row Here

            DataClasses1DataContext db = new DataClasses1DataContext();

            System.Data.DataRowView SelectedRowView;
            newCityCollectionDataSet.DocumentsRow SelectedRow;

            SelectedRowView = (System.Data.DataRowView)documentsBindingSource.Current;
            SelectedRow = (newCityCollectionDataSet.DocumentsRow)SelectedRowView.Row;


            var matchedDocument = (from c in db.GetTable<Document>()
                                   where c.DocIDKey == SelectedRow.DocIDKey
                                   select c).SingleOrDefault();

            db.Documents.DeleteOnSubmit(matchedDocument);
            db.SubmitChanges();

            LoadCaseNumberKey(matchedDocument.CaseNumberKey, false, "documents");
            this.dataRepeater1.EndResetItemTemplate();
        }


    }

Any help would be great..

Answer 1

My guess is that your are mixed up between your documentsBindingSource and your dataRepeater .

What you "see" visually is the dataRepeater, while what you "get", is the documentsBindingSource.Current (that you retrieve as being SelectedRowView )
which is always set to 0 index. This is an all-too-common Winforms control trap.
