c# - 单击 Gridview 中的链接按钮时写入 Gridview 行

Question

我有一个每行Gridview都有一个 Close的。linkbutton当用户单击 CloseButton时，它​​应该将数据写入该特定行。我的数据已经写入，但是当我单击第三行linkbutton关闭时，它会写入第一行。我希望它写到第三行。

Width="688px" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"

<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
<Columns>
    <asp:TemplateField HeaderText="Transaction Type" SortExpression="TransTypeDesc">
        <EditItemTemplate>
            <asp:DropDownList ID="DDLTrans" runat="server" DataSourceID="SqlDataSourceTrans"
                DataTextField="TransTypeDesc" DataValueField="TransTypeId">

            <asp:SqlDataSource ID="SqlDataSourceTrans" runat="server" ConnectionString="<%$ ConnectionStrings:iQueueConnectionString %>"
                SelectCommand="SELECT [TransTypeId], [TransTypeDesc] FROM [tblTransType]"></asp:SqlDataSource>

        <ItemStyle HorizontalAlign="Center" />
    </asp:TemplateField>
</Columns>

protected void CloseClick_Click(object sender, EventArgs e)
    {
        var StartLink = (Control)sender;
        GridViewRow row = (GridViewRow)StartLink.NamingContainer;
        firstCellText = row.Cells[0].Text;
    }

Answer 1

使用 a CommandFieldwith a selectproperty 而不是 a TemplateFieldwith aLinkButton

并在YourGridView_SelectedIndexChanged handler使用中YourGridView.SelectedIndex处理您单击的行。

然后你可以说：

firstCellText = row.Cells[YourGridView.SelectedIndex].Text;

Answer 2

解决了。我刚刚做了一个查询并根据我的 firstcellText 值显示它，从而解决了问题。
