从RowCommand获取数据

Question

我有一个显示产品版本的网格，并有一些链接按钮，如编辑、删除、预览等。在单击编辑按钮时，我希望获得产品ID和版本ID，并将其重定向到可以编辑产品详细信息的某个xyz.aspx页面。

下面是我的网格的外观：

<asp:GridView ID="grdBindVersion" runat="server" AutoGenerateColumns="false" 
            onrowcommand="grdBindVersion_RowCommand" >



        <RowStyle BorderStyle="Solid" BorderWidth="1px" />
        <Columns>
            <asp:BoundField datafield="HistoryId"  HeaderText="Version ID.">
                        <HeaderStyle CssClass="grid"></HeaderStyle>
            </asp:BoundField>

            <asp:BoundField datafield="Title" HeaderText="Title">
                        <HeaderStyle CssClass="grid"></HeaderStyle>
            </asp:BoundField>

             <asp:TemplateField HeaderText = "Edit">
                   <ItemTemplate>

                       <asp:LinkButton ID="Edit" runat="server" CommandArgument='<%# Container.DataItem %>'  CommandName ="Add">Edit</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Delete">
                   <ItemTemplate>
                           <asp:LinkButton ID="Delete" runat="server">Delete</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Add Sub Page">
                   <ItemTemplate>
                            <asp:LinkButton ID="AddSubPage" runat="server">Add Sub Page</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Add Rank">
                   <ItemTemplate>
                            <asp:LinkButton ID="AddRank" runat="server">Add Rank</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Approve/DisApprove">
                   <ItemTemplate>
                           <asp:LinkButton ID="ApproveStatus" runat="server">Approve/DisApprove</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Complete">
                   <ItemTemplate>
                            <asp:LinkButton ID="Complete" runat="server">Complete</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Preview">
                   <ItemTemplate>
                            <asp:LinkButton ID="Preview" runat="server">Preview</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText = "Comment">
                   <ItemTemplate>
                            <asp:LinkButton ID="Comment" runat="server">Comment</asp:LinkButton>
                   </ItemTemplate>
              </asp:TemplateField>

        </Columns>
        </asp:GridView>

我正在跟踪单击GridView的GridView事件中的链接按钮。在这里，我想得到VersionID和ProductID，然后重定向到另一个页面。请帮帮我。我对编码很陌生。我做了一点谷歌，但没有一个解决方案对我有帮助。

Answer 1

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Edit")
    {
        GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
        // row contains current Clicked Gridview Row
        String VersionId = row.Cells[CellIndex].Text;
        .............
        .............
        //e.CommandArgument  -- this return Data Key Value
    }
}

您可以为Gridview的OnRowCommand分配多个任务.

        <asp:TemplateField HeaderText="Feedback Form">
            <ItemTemplate>
                <asp:LinkButton runat="server" ID="lnkFB" Enabled="true" Text="CREATE"
                        CommandArgument='<%# Eval("ApprenticeshipID") + ";" + Eval("OrganisationID") + ";" + Eval("StudentID") %>' CommandName="btnFB" 
            </ItemTemplate>
            <HeaderStyle HorizontalAlign="Center" />
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>

在代码隐藏中，逐个提取参数并将它们分配给会话变量，供以后使用.

string[] arg = new string[2]; //say up to 3 arguments (ie: 0,1,2)
arg = e.CommandArgument.ToString().Split(';');
Session["ApprenticeshipID"] = arg[0]; //I only need first argument
GenerateFeedbackForm(Session["ApprenticeshipID"].ToString());

将VersionID和ProductID指定为GridView的DataKeyNames，然后通过查询字符串传递这两个值。
