GridView 里面如何获取boundField点击的所在行的数据,在线

[孔方发发]

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BackColor="White"
BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1"
DataSourceID="SqlDataSource1" GridLines="None" AllowPaging="True" OnRowCommand="GridView1_RowCommand" DataKeyNames="帐号">
<FooterStyle BackColor="#C6C3C6" ForeColor="Black" />
<Columns>
<asp:BoundField DataField="帐号" HeaderText="帐号" SortExpression="帐号" />
<asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />
<asp:BoundField DataField="身份证号" HeaderText="身份证号" SortExpression="身份证号" />
<asp:BoundField DataField="工号" HeaderText="工号" SortExpression="工号" />
<asp:ButtonField CommandName="EditRole" Text="配置角色" />
</Columns>
<RowStyle BackColor="#DEDFDE" ForeColor="Black" />
<SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" />
<HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" />
</asp:GridView>

我在

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "EditRole")
{
string m_Login = "";
m_Login = GridView1.DataKeys[GridView1.Rows..DataItemIndex].Value.ToString();

currencyLib.ShowMessage(this, "",m_Login);

}
}

行 38: currencyLib.ShowMessage(this, "",m_Login);

[cpp2017]

this.GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Value

[hy_lihuan]

string MessageID = gvMessage.DataKeys[e.Row.RowIndex][0].ToString();

2005里面

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
string pid = GridView1.SelectedDataKey.Value.ToString();
if (cart != null)
{
cart.DeleteItem(pid);
Profile.ShoppingCart.DeleteItem(pid);
Total.Text = String.Format("合计:{0:c}", cart.TotalCost);
//删除后的绑定,下面可以不要因为Page_Load事件绑定了
//ShoppingCart cart = (ShoppingCart)Session["MyShoppingCart"];
//GridView1.DataSource = cart.Orders;
GridView1.DataBind();
}
}
