將GridViewComboBoxColumn綁定到數據源

Question

我已經知道如何指定數據源，但是由於它沒有填充，所以我想你需要某種bind（）命令來填充編輯表單中的組合框 下面是我怎麼綁定數據源到comboboxcolumn（是的，我敢肯定，DS在其數據行）

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

所以任何人都可以告訴我，我怎麼能現在居住在編輯模式下的comboboxcolumn？

編輯

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

這裏是一個應該工作的代碼：

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"; 

另外，請參閱GridViewDataComboBoxColumn Class話題。

UPDATE您的代碼應該在CellEditorInitialize事件，如下所示實現：

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(); 
     } 
    }
