Question

我有一个表列名为Status，它取三个值1,2或3.现在，我想在三个GridView中的任何一个中显示另一个列Name1，具体取决于Status。此外，我还有链接按钮，可以重定向到不同的Web表单。

这是我获得的输出。 GridView的ID是GridView1

这是我使用的代码

    protected void EditFile(object sender, EventArgs e)
    {
        Response.Redirect("EditResume.aspx");
    }

    protected void EditFile1(object sender, EventArgs e)
    {
        Response.Redirect("EditResume1.aspx");
    }
}

但是，无论状态如何，所有数据都显示在GridView1中。

在ASP.Net和C＃中处理多个GridView
