关于asp.net中gridview的问题 [英] Question about gridview in asp .net

问题描述

您好我尝试了以下但错误来了



protected void GridApprove_RowDataBound（object sender，GridViewRowEventArgs e）

{

if（e.Row.RowType == DataControlRowType.DataRow）

{



标签lbl_pending = new Label（） ;

标签lbl_approved = new Label（）;

int val_approved = Convert.ToInt32（e.Row.Cells [17] .ToString（））;

int val_checked = Convert.ToInt32（e.Row.Cells [18] .ToString（））;

if（val_approved == 2 && val_checked == 2）

{

Button btn_accept = new Button（）;

Button btn_discard = new Button（）;

btn_accept.Text =ACCEPT ;

btn_discard.Text =DISCARD;

e.Row.Cells [7] .Controls.Add（btn_accept）;

e.Row.Cell s [7] .Controls.Add（btn_discard）;

}



//tbox.Text=你没有添加的文字或与数据字段绑定;

//e.Row.Cells[7].Controls.Add(tbox),

}





生成的异常{指定的参数超出了有效值的范围。\\\\参数名称：索引}

推荐答案

下面是实现此目的的一种方法的参考代码。

Below is the reference code of one way to achieve this.

<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound"
            Height="100px">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="btn1" runat="server" Text="Approve" CommandArgument= />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

protected void Page_Load(object sender, EventArgs e)
     {
         string [] dataSource = { "3","1", "2" };
         if (!IsPostBack)
         {
             GridView1.DataSource = dataSource;
             GridView1.DataBind();
         }
     }

     protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
     {

         if (e.Row.RowType == DataControlRowType.DataRow)
         {
             if (e.Row.DataItem.ToString() == "1")
             {
                 var cont = e.Row.FindControl("btn1");
                 e.Row.Cells[0].Controls.Remove(cont);
                 e.Row.Cells[0].Text = "Not Approved";
             }
         }
     }
