这是隐藏文件我的代码...

And here is my code behind file...

protected void BindGridviewData()
{

    var role = from MembershipUser u in Membership.GetAllUsers()
                select new
                {
                    User = u.UserName,
                    Role = string.Join(",", Roles.GetRolesForUser(u.UserName))
                };

    DataTable dTable = new DataTable();
    dTable.Columns.Add("col0", typeof(string));
    dTable.Columns.Add("col1", typeof(bool));
    dTable.Columns.Add("col2", typeof(bool));
    dTable.Columns.Add("col3", typeof(bool));
    foreach (MembershipUser u in Membership.GetAllUsers())
    {
        DataRow dRow = dTable.NewRow();
        dRow[0] = u.UserName;

        string[] roles = Roles.GetRolesForUser(u.UserName);
        dRow[1] = roles.Contains("Admin") ? true : false;
        dRow[2] = roles.Contains("DPAO User") ? true : false;
        dRow[3] = roles.Contains("GeneralUser") ? true : false;
        dTable.Rows.Add(dRow);
    }
    GridView1.DataSource = dTable;
    GridView1.DataBind();
}

请专家帮我，因为我不知道如何做到这一点？在此先感谢...

推荐答案

如果你想按按钮记录STRONG>试试这个：

If you want Delete record by Button try this:

GridView控件之外添加一个按钮，删除：

Add a Button outside of gridview for Delete:

<asp:Button ID="cmdDelete" runat="server" onclick="cmdDelete_Click" Text="Delete" />

后面的代码：

Code behind:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindGridviewData();
    }
}
protected void BindGridviewData()
{
    DataTable dTable = new DataTable();
    dTable.Columns.Add("col0", typeof(string));
    dTable.Columns.Add("col1", typeof(bool));
    dTable.Columns.Add("col2", typeof(bool));
    dTable.Columns.Add("col3", typeof(bool));
    foreach (MembershipUser u in Membership.GetAllUsers())
    {
        DataRow dRow = dTable.NewRow();
        dRow[0] = u.UserName;
        string[] roles = Roles.GetRolesForUser(u.UserName);
        dRow[1] = roles.Contains("Admin") ? true : false;
        dRow[2] = roles.Contains("DPAO User") ? true : false;
        dRow[3] = roles.Contains("GeneralUser") ? true : false;
        dTable.Rows.Add(dRow);
    }
    GridView1.DataSource = dTable;
    GridView1.DataBind();
}
protected void cmdDelete_Click(object sender, EventArgs e)
{
    foreach (GridViewRow row in GridView1.Rows)
    {
        CheckBox chk = (CheckBox)row.FindControl("chkChild");
        if (chk.Checked)
        {
            Label username = (Label)row.FindControl("Label1");
            Membership.DeleteUser(username.Text);
            BindGridviewData();
        }
    }
}
