运行时选择AspxGridView

Question

我的页面上有aspxGridView，我在运行时创建了列。我还添加CommandColumn并将ShowSelectCheckBox设置为true。但是，在我选择一行并单击按钮以获取行值后，AspxGridView.Selection.Count将返回0。我在AspxButtons Click事件上创建此GridView也用于分页，在Page_Init上创建gridView。以下是创建AspxGridView：

的代码

Colenter code hereorCollection colorCol = ConfAttributesManager.Instance
                                                               .GetColors();

if (colorCol.Count > 0)
{
    GridViewDataTextColumn grdColorCodeColumn = new GridViewDataTextColumn();
    grdColorCodeColumn.FieldName = "ColorCode";

    GridViewDataTextColumn grdDescriptionColumn = new GridViewDataTextColumn();
    grdDescriptionColumn.FieldName = "Description";

    gv_Attributes.Columns.Clear();
    gv_Attributes.Columns.Add(grdColorCodeColumn);
    gv_Attributes.Columns.Add(grdDescriptionColumn);
    GridViewCommandColumn grdCmdColumn = new GridViewCommandColumn();
    grdCmdColumn.ShowSelectCheckbox = true;
    grdCmdColumn.VisibleIndex = 0;
    gv_Attributes.Columns.Add(grdCmdColumn);

    gv_Attributes.DataSource = colorCol;
    gv_Attributes.DataBind();
 }

我不知道我在哪里弄错了？

感谢您的帮助。

您似乎没有指定行选择操作所需的ASPxGridView.KeyFieldName属性：

gv_Attributes.KeyFieldName = "ColorCode";
//gv_Attributes.KeyFieldName = Unique Key Field;
