Question

我正在尝试在gridview中绑定的用户列表中禁用admin角色的删除按钮。

所以，我选择rowdatabound选项，我可以根据条件禁用，就像检查角色列的文本一样。

如果角色列文本是“Admin”，那么我必须禁用我自定义的“删除”按钮。

不幸的是，在获取数据时我无法获取单元格的文本。我使用了如下语句：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Button btn = (e.Row.FindControl("Delbutton") as Button);

        if(e.Row.Cells[7].Text == "ADMIN")
        {
            btn.Enabled = false;
        }
    }
}

我的aspx页面：

       AutoGenerateColumns="False" 
       OnPageIndexChanging="GridView1_PageIndexChanging" 
       PagerSettings-Mode="Numeric"

Please check the image of my code on debugger

This was my data on page after loaded

单元格文本始终在Gridview rowdatabound中变为空字符串（“”）
