解决方案

在你的 GridView_RowCommand 事件您可以访问 GridView1.FooterRow页脚控制.FindControl 方法。

 保护无效GridView1_RowCommand（对象发件人，GridViewCommandEventArgs E）
{
    如果（e.CommandName.Equals（插入，StringComparison.OrdinalIgnoreCase））
    {
        文本框txtSomeNewValue =（（文本框）GridView1.FooterRow.FindControl（txtSomeNewValue））;
        字符串theTextValue = txtSomeNewValue.Text;
    }
}
 

更新：包裹在一个if块中的code，检查是否的CommandName 是您所期望的东西。也用于此事件删除，编辑等，因此，如果你不把它包起来这个，你可能最终运行code一个事件你没有打算。

                <FooterTemplate>
                    <asp:Button ID="ButtonOK" Text="Confirm" runat="server" />
                </FooterTemplate>
            </asp:TemplateField>
        </Columns>

解决方案

Inside your GridView_RowCommand Event you can access the footer control by GridView1.FooterRow.FindControl method.

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName.Equals("Insert", StringComparison.OrdinalIgnoreCase))
    {
        TextBox txtSomeNewValue = ((TextBox)GridView1.FooterRow.FindControl("txtSomeNewValue"));
        string theTextValue = txtSomeNewValue.Text;
    }
}

Update: wrapped the code in an if block that checks if the commandname is what you were expecting. This event is also used for delete, edit, etc, so you might end up running the code for an event you didnt intend if you dont wrap it in this.
