Question

我使用了Dx AspxGridView.And我尝试从这个网格绑定一些标签。

我在这个网格中有一行，有12列。

我希望是这样的：

Label1.Tex = Column1的值

Label2.Tex = Column2的值

Label3.Tex = Column3的值

  <dx:ASPxLabel runat="server" ID="Label1" Text=""></dx:ASPxLabel>

  <dx:ASPxLabel runat="server" ID="Label2" Text=""></dx:ASPxLabel>

  <dx:ASPxLabel runat="server" ID="Label3" Text=""></dx:ASPxLabel>
  .

  .  

  .

Label12.Tex = Column12的值

我的代码：

     protected void ASPxGridView1_HtmlRowCreated(object sender, 
     ASPxGridViewTableRowEventArgs e)

     {
        if (e.RowType != DevExpress.Web.ASPxGridView.GridViewRowType.Data) return;

        DevExpress.Web.ASPxEditors.ASPxLabel label = 
        ASPxGridView1.FindRowCellTemplateControl(e.VisibleIndex, null, "Label1") as 
        DevExpress.Web.ASPxEditors.ASPxLabel;

  //for integer value of column
        int Value=(int) e.GetValue("Column1");
        label.Text = string.Format("{0}",Value);

    DevExpress.Web.ASPxEditors.ASPxLabel label2 = 
    ASPxGridView1.FindRowCellTemplateControl(e.VisibleIndex, null, "Label3") as 
    DevExpress.Web.ASPxEditors.ASPxLabel;

        int Value2=(int) e.GetValue("Column2");
        label2.Text = string.Format("{0}",Value2);

   DevExpress.Web.ASPxEditors.ASPxLabel label3 = 
   ASPxGridView1.FindRowCellTemplateControl(e.VisibleIndex, null, "Label3") as 
   DevExpress.Web.ASPxEditors.ASPxLabel;


  //for string value of column
   string Value3=(string) e.GetValue("Column3");
   label.3Text = string.Format("{0}",Value3);

  }

我收到此错误

 System.NullReferenceException: Object reference not set to an instance of an object.

在第

行

 label.Text = string.Format("{0}",Value);

我解决了我的问题。

  protected void ASPxGridView1_CustomColumnDisplayText(object sender, 
   ASPxGridViewColumnDisplayTextEventArgs e)
    {
        if (e.Column.FieldName == "Column1")
        {
            Label1.Text = e.Value.ToString();
        }

        if (e.Column.FieldName == "Column2")
        {

            Label2.Text = e.Value.ToString();
        }

       . 

       .

       if (e.Column.FieldName == "Column12")
        {

            Label12.Text = e.Value.ToString();
        }

    }

如何绑定AspxGridView的标签？
