DatagridView新行添加错误

Question

我想在Datagrid中添加新行但是有错误。

错误：当控件受数据限制时，无法以编程方式将行添加到DataGridView的行集合中。

     row = new string[] { "0", "1", hesab_nomresi,soyad,ad,ataadi,vesiqe,teskilat_kodu,tevellud,nomre,cins };
     kartsifarishiGridView.Rows.Add(elaveEtme.row);

     AllowUserToAddRow = false;

数据源（从作者评论中添加）

string sqlSorgu = "SELECT" + " customer.id, + " IIf (customer.cins = 'M','Kişi','Qadın') AS Cins " + " FROM customer ORDER BY customer.id ASC";
OleDbDataAdapter dataAdapter = new OleDbDataAdapter(sqlSorgu, Program.esas.bazayaQosul); 
DataTable dataTable = new DataTable(); 
set = new DataSet(); 
set.Tables.Add(dataTable); 
dataAdapter.Fill(dataTable);

kartsifarishiGridView.DataSource = dataTable;

Answer 1

您可以直接将新行添加到绑定到网格的数据源，并调用kartsifarishiGridView.DataBind（）;

new string[] { "0", "1", hesab_nomresi,soyad,ad,ataadi,vesiqe,teskilat_kodu,tevellud,nomre,cins };

这个想法是你不能在绑定的datagridview中添加一行。您必须将它添加到datagridview绑定到的结构（数据表）。

示例：

       string sqlSorgu = "SELECT" + " customer.id," + " IIf (customer.cins = 'M','Kişi','Qadın') AS Cins " + " FROM customer ORDER BY customer.id ASC"; 

        OleDbDataAdapter dataAdapter = new OleDbDataAdapter(sqlSorgu, Program.esas.bazayaQosul); 
        DataTable dataTable = new DataTable(); 
        set = new DataSet(); 
        set.Tables.Add(dataTable); 
        dataAdapter.Fill(dataTable);

        //  Here is the code for adding new row
        dataTable.Rows.Add(new string[]
                               {
                                   "0", "1", hesab_nomresi, soyad, ad, ataadi, vesiqe, teskilat_kodu, tevellud, nomre,
                                   cins
                               });

        kartsifarishiGridView.DataSource = dataTable;

Answer 2

以下是如何解决这个通用方法：

myDataGridView.BindingContext[dg.DataSource, dg.DataMember].AddNew();
