Question

我创建了一个名为“FamilyView”的视图来连接2个表（Families和SStatus）并用第二个表（SStatus）中存在的名称替换第一个表（Families）中的id（该列现在称为“Status” “）

此视图现在显示在用户可以修改的数据网格视图中

        Sda = new SqlDataAdapter("Select * from FamilyView",con);
        Sda.Fill(ds);
        dg.DataSource = ds.Tables[0];
        dg.Refresh();

我想要的是将列单元格“状态”转换为包含SStatus中所有名称的组合框

        SqlDataAdapter sadapter = new SqlDataAdapter("Select * From SStatus", con);
        DataSet ds1 = new DataSet();
        sadapter.Fill(ds1);

我找到了这段代码：

        DataGridViewComboBoxCell ComboColumn = (DataGridViewComboBoxCell)(dg.Rows[i].Cells[0]);
        ComboColumn.DataSource = ds1.Tables[0];
        ComboColumn.DisplayMember = "Name";

但我不能替换细胞

和这段代码，但我不知道如何使用它：

Adding bound combobox to datagridview

        BindingSource StatusBD = new BindingSource();
        StatusBD.DataSource = ds1;


        DataGridViewComboBoxColumn colType = new DataGridViewComboBoxColumn();
        colType.HeaderText = "Status";
        colType.DropDownWidth = 90;
        colType.Width = 90;
        //colType.DataPropertyName = "Name";
        colType.DataSource = ds;
        colType.DisplayMember = "Name";
        colType.ValueMember = "IdStatus";

        dg.Columns.Insert(dg.Columns.GetColumnCount(DataGridViewElementStates.None) - 1, colType);

您的数据源为空：它应包含2个表：一个包含SStatus，另一个包含Families。

然后按照我的帖子关注：

          DataGridViewComboBoxColumn colType = new DataGridViewComboBoxColumn();
        BindingSource wizardBindingSource = new BindingSource();
        wizardBindingSource.DataSource = dataSet; 
        wizardBindingSource.DataMember = "protocol"; // This is the table in the set
        colType.HeaderText = "Type";
        colType.DropDownWidth = 90;
        colType.Width = 90;
        colType.DataPropertyName = "wizardProtocol";
        colType.DataSource = wizardBindingSource;
        colType.DisplayMember = "protocolName";
        colType.ValueMember = "idprotocols"

这里idProtocol（在“pcap”表中被称为协议）被映射到protocolName。

将DGV中的列修改为绑定到DataBase的Combobox
