I have also tried as suggested at http://www.codeproject.com/Questions/103062/How-to-get-the-value-of-a-selected-row-in-gridview My code is as follows<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns = "False" AllowPaging="true" OnPageIndexChanging="gdv1_OnPaging" PageSize="5" DataKeyNames = "Material" OnRowDataBound = "gv1_OnRowDataBound" OnSelectedIndexChanged = "gv1_SelectedIndexChanged" CSSClass= "~/Styles" EnableViewState="False" PagerSettings-Mode="Numeric" AutoGenerateSelectButton="true"> protected void gv1_OnRowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" + e.Row.RowIndex); e.Row.ToolTip = "Click to select this row."; } }protected void gv1_SelectedIndexChanged(object sender, EventArgs e) { int selectedIndex = GridView1.SelectedIndex; string selectedMaterial = (GridView1.DataKeys[selectedIndex]).Value.ToString(); Server.Transfer("Details.aspx"); }//code in details.aspx protected void Page_Load(object sender, EventArgs e) { if (this.Page.PreviousPage != null) { GridView GridView1 = GridView)this.Page.PreviousPage.FindControl("GridView1"); int selectedIndex = GridView1.SelectedIndex; string selectedMaterial = (GridView1.DataKeys[selectedIndex]).ToString();} 我的尝试： What I have tried://int selectedIndex = Convert.ToInt32(GridView1.SelectedDataKey[1].ToString()); int selectedIndex = GridView1.SelectedIndex; string customID = (GridView1.DataKeys[selectedIndex]["pkCityId"]).ToString(); 推荐答案 我的尝试： What I have tried://int selectedIndex = Convert.ToInt32(GridView1.SelectedDataKey[1].ToString()); int selectedIndex = GridView1.SelectedIndex; string customID = (GridView1.DataKeys[selectedIndex]["pkCityId"]).ToString(); <asp:gridview id="GridView1" runat="server" autogeneratecolumns="False" allowpaging="true" OnPageIndexChanging="gdv1_OnPaging" PageSize="5" DataKeyNames = "Material,pkCityId" OnRowDataBound = "gv1_OnRowDataBound" OnSelectedIndexChanged = "gv1_SelectedIndexChanged" CSSClass= "~/Styles" EnableViewState="False" PagerSettings-Mode="Numeric" AutoGenerateSelectButton="true"</asp:gridview> 亲切的问候Kind Regards 这篇关于将gridview的selecteditem值作为字符串传递给另一个页面的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
