gridview设置行号与RowCommand事件中获取行号

aspx页面：

 

<Columns>
                    <asp:BoundField DataField="id" HeaderText="id" InsertVisible="False"
                        ReadOnly="True" SortExpression="id" Visible="False" />
                    <asp:BoundField HeaderText="步骤">
                    <HeaderStyle Width="50px" />
                    </asp:BoundField>

</Columns>

 

 

.cs文件动态生成行号

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowIndex > -1)
            {
                e.Row.Cells[1].Text = Convert.ToString(e.Row.RowIndex + 1);

            }
        }

 

 

 

在RowCommand中获取行号

 

在模板列中添加=<%# Container.DataItemIndex + 1 %>

 <ItemTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false"
                                CommandName="modify" Text="修改" CommandArgument=<%# Container.DataItemIndex + 1 %>></asp:LinkButton>
                        </ItemTemplate>

 

 

 

cs文件

        protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            GridView gv = ((GridView)sender);
            int rowNum = int.Parse(e.CommandArgument.ToString()) - 1;
            txbBeizhu.Text = gv.Rows[rowNum].Cells[2].Text;
            ModalPopupExtender1.Show();
        }
