Question

我已经知道如何指定数据源但是还没有这样做它还没有填充，所以我认为你需要某种bind（）命令来填充编辑表单中的组合框下面是我将数据源绑定到组合框的方式（是的，我确定ds中有数据行）

(ASPxGridView4.Columns["Naam"] as GridViewDataComboBoxColumn).PropertiesComboBox.DataSource = ds as DataSet;

那么有人能告诉我现在如何在编辑模式中填充组合框吗？

修改

protected void ASPxGridView4_InitNewRow(object sender, DevExpress.Web.Data.ASPxDataInitNewRowEventArgs e)
    {
        if (dt.Rows.Count < 1)
        {
            ds = Session["ds"] as DataSet;
        }
        GridViewDataComboBoxColumn column = (ASPxGridView4.Columns["Naam"] as GridViewDataComboBoxColumn);
        column.PropertiesComboBox.DataSource = ds.Tables[0];
        column.PropertiesComboBox.ValueField = "Naam";
        column.PropertiesComboBox.ValueType = typeof(string);
        column.PropertiesComboBox.TextField = "Naam";
    }

Answer 1

以下代码应该有效：

DataSet dataSet = ds as DataSet;
GridViewDataComboBoxColumn column = (ASPxGridView4.Columns["Naam"] as GridViewDataComboBoxColumn);
column.PropertiesComboBox.DataSource = dataSet.Tables[0];
column.PropertiesComboBox.ValueField = "SomeValueField";
column.PropertiesComboBox.ValueType = typeof(int);  // type of the SomeValueField
column.PropertiesComboBox.TextField = "SomeTextField";

另请参阅GridViewDataComboBoxColumn Class主题。

更新您的代码应在CellEditorInitialize事件中实施，如下所示：

protected void ASPxGridView1_CellEditorInitialize(object sender, ASPxGridViewEditorEventArgs e) {
        if(e.Editor is ASPxComboBox) {
            ASPxComboBox combo = ((ASPxComboBox)e.Editor);
            combo.DataSource = dataSet.Tables[0];
            combo.TextField = "Naam";
            combo.ValueField = "Naam";
            combo.DataBindItems();
        }
    }

将GridViewComboBoxColumn绑定到数据源
