将DGV中的列修改为绑定到数据库的组合框

本文关键字:数据库 组合 绑定 修改 DGV | 更新日期: 2023-09-27 18:15:18

我创建了一个名为"FamilyView"的视图来连接两个表(Families和SStatus),并将第一个表(Families)中的id替换为第二个表(SStatus)中存在的名称(该列现在称为"Status")

这个视图现在显示在一个数据视图中,用户可以修改

        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"转换为包含来自SStatus的所有名称的组合框

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

我发现了这个代码:

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

但是我不能替换单元格

和这段代码,但我不确定如何使用它:

添加绑定组合框到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);

你的数据源是空的:它应该包含2个表:一个是SStatus,一个是Families。

然后在你的帖子中跟随我的as:

          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"

此处idProtocol(在"pcap"表中作为protocol引用)被映射到protocolName
