网格视图

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
    AllowSorting="True" PagerSettings-Position="TopAndBottom"
    PagerSettings-Mode="Numeric" PageSize="40" CellPadding="4" DataSourceID="dsEquipmentGridView"
    ForeColor="#333333" GridLines="Horizontal" Style="font-size: x-small" AutoGenerateColumns="False"
    DataKeyNames="IREF" OnRowEditing="GridView1_RowEditing" OnRowUpdated="GridView1_RowUpdated"
    OnSorted="GridView1_Sorted" OnSorting="GridView1_Sorting" OnPageIndexChanged="GridView1_PageIndexChanged1"
    OnPageIndexChanging="GridView1_PageIndexChanging" OnSelectedIndexChanged="GridView1_SelectedIndexChanged"
    OnSelectedIndexChanging="GridView1_SelectedIndexChanging" OnRowCommand="GridView1_RowCommand"
    BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" 
    OnRowCancelingEdit="GridView1_RowCancelingEdit" onload="GridView1_Load" 
    ondatabound="GridView1_DataBound">
    <PagerSettings Position="TopAndBottom" />
    <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
    <Columns>
 <asp:CommandField ShowDeleteButton="False" ShowSelectButton="true" EditText="QuickEdit"
     HeaderText="Manage" SelectText="Manage" />

对于加载的第一页，如果我单击命令字段，它会显示正确的 DataKey 值。

但是，如果我更改为下一页结果，则在选择记录时，相应的值不正确。它似乎保留了前一页信息。我该如何克服呢？

编辑：

在 GridView1_SelectedIndexChanged 方法中，我使用了以下内容：

    // Determine the index of the selected row.
    int index = GridView1.SelectedIndex;

    // Display the primary key value of the selected row.
    HttpContext.Current.Response.Write("The primary key value of the selected row is " + GridView1.DataKeys[index].Value.ToString() + ".<br>");

    GridViewRow row = GridView1.Rows[index];

    int rowindex = row.RowIndex;
    HttpContext.Current.Response.Write("rowindex-> " + rowindex.ToString() + "<br>");

    int ID = (int)GridView1.DataKeys[row.DataItemIndex - (GridView1.PageIndex * GridView1.PageSize)].Value;

    HttpContext.Current.Response.Write("row.DataItemIndex" + ID.ToString()+"<br>");

    int Userid = Convert.ToInt32(GridView1.DataKeys[index].Value);

    HttpContext.Current.Response.Write("Userid" + Userid.ToString() + "<br>");

分页后我无法获得正确的值。

使用分页时，我们可以得到准确的行索引（totalrows在gridview中从0到计数），在获取时datakey，我们需要传递当前页面的行索引。

使用下面的行来获取当前页面索引并获取数据键：

// Get the correct row index since there is paging
int idx = gridViewRow.DataItemIndex - TestGridView.PageIndex * TestGridView.PageSize;

I may be late. But for others, i reply this.

"Rebind gridview again before using DataKey array"

it works for me. Hope it works for others too.

前一阵子修好了。正在使用第三方 GridView 助手类。这破坏了 GridView 的正常功能。
