Question

我正在尝试获取gridview的单元格值。我可以通过像这样的标签名称访问它

Label cell1 = ((Label)e.Row.FindControl("cellLabel"));

有15-20列，所以我想通过索引访问单元格。我用e.Row.Cells[2].Text试了一下，但我在这里得到了空。

我无法直接访问gridview，因为它是内部gridview。如何在RowDatabound中访问单元格值？

Gridview示例

<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false" CssClass="Grid"

    DataKeyNames="CustomerID" OnRowDataBound="OnRowDataBound">

    <Columns>

        <asp:TemplateField>

            <ItemTemplate>

                <img alt = "" style="cursor: pointer" src="images/plus.png" />

                <asp:Panel ID="pnlOrders" runat="server" Style="display: none">

                    <asp:GridView ID="gvOrders" runat="server" AutoGenerateColumns="false" CssClass = "ChildGrid">

                        <Columns>

                            <asp:BoundField ItemStyle-Width="150px" DataField="OrderId" HeaderText="Order Id" />

                            <asp:BoundField ItemStyle-Width="150px" DataField="OrderDate" HeaderText="Date" />

                        </Columns>

                    </asp:GridView>

                </asp:Panel>

            </ItemTemplate>

        </asp:TemplateField>

        <asp:BoundField ItemStyle-Width="150px" DataField="ContactName" HeaderText="Contact Name" />

        <asp:BoundField ItemStyle-Width="150px" DataField="City" HeaderText="City" />

    </Columns>

</asp:GridView>

gvOrders是内部网格视图。

Answer 1

您可以直接从数据源

获取

string str = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "YourColumnName"));

要通过索引访问它，您可以尝试

string str = ((DataBoundLiteralControl)e.Row.Cells[x].Controls[y]).Text;

Answer 2

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string name = e.Row.Cells[0].Text;
        }
    }
