GridView 中带有链接按钮的行命令

Question

我有两个 GridView。 GridView1 在一列中包含 2 个链接按钮。当我在 GridView1 中选择链接按钮时，链接按钮的详细信息应显示在 GridView2 中。

GridView2 包含一个带有单选按钮的列。我需要从数据库中动态填充单选按钮。

如何使用 GridView1_RowCommand 填充 GridView2 的单选按钮列表？或者我可以从 GridView2 的 RowDataBound 事件中获取它吗？

后面的代码：

protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
{            
    if (e.CommandName == "Yes")
    {           
        GridViewRow gvRow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
        int RowIndex = gvRow.RowIndex;            
        Int32 iAppID = Convert.ToInt32(GridView1.DataKeys[gvRow.RowIndex].Value.ToString());               

        dset = userApps.UserSelectedApp(iUserID, iAppID);
        if (dset.Tables[0].Rows.Count > 0)
        {
            GridViewRow gRow = GridView2.Rows[RowIndex];//I need to create object to this Gridview2, and fill the radiobutton list with some values
            RadioButtonList rdbtnSubPlans = (RadioButtonList)e.gRow.Cells[2].FindControl("rdbSubPlans");

            ds = userApps.UpgradePlans(iUserID, iAppID);
            if (ds != null)
            {
                rdbtnSubPlans.DataSource = ds;
                rdbtnSubPlans.DataValueField = "PlanID";
                rdbtnSubPlans.DataTextField = "Plans";
                rdbtnSubPlans.DataBind();
            }
        }
    }
    if (e.CommandName == "No")
    {}
     dtset = user.UserSelectedAppication(iUserID, iAppID);    
     GridView2.DataSource = dtset;
     GridView2.DataBind();
     MultiView1.SetActiveView(viewRenewOrUpdate);                
    }
}  

GridViews 的 ASPX 代码

    OnRowDataBound="GridView1_RowDataBound" OnRowCommand="GridView1_RowCommand" 
    OnSorting="GridView1_Sorting" OnDataBound="GridView1_DataBound"

        </asp:TemplateField>
        < Some Bound Fields>

            </ItemTemplate>
        <ItemStyle CssClass="col" />
    </Columns>
</asp:GridView>

Answer 1

先填充Gridview2，然后做如下修正：

GridViewRow gRow = GridView2.Rows[0]
RadioButtonList rdbtnPlans = (RadioButtonList)gRow.FindControl("rdbPlans");
