问题描述
如何获取datagridview选定的行值到文本框，单选按钮和下拉列表，该表单在另一个Windows窗体中以C#格式显示为最新日期
得到此错误(对象引用未设置为对象的实例.)
这是我的form1代码
--------------------------
公共静态字符串性别，分区，类型，事件，记分，中继，注释，选择方式；
public static int回合，Scoreteam，时间精度，晋级
公共frmAddEditEvents()
{
如果(Selectmode =="update")
fillRecord();
如果(Selectmode ==插入")
InitializeComponent();
}
公共无效fillRecord()
{
rdbMale.Text =性别；
cmbDivison.Text =除法;
rdbRun.Text =类型;
cmbEvent.Text =事件;
chkScore.Text = Scoreeve;
chkRelay.Text =中继;
nudRounds.Value =回合;
nudScores.Value = Scoreteam;
nudTimeprecision.Value = timeprecison;
txtEventnote.Text =注释;
numericUpDown1.Value =进度；
btnSave.Text ="update";
}
这是表格2
-------------------------
私有void tsbtnEdit_Click(对象发送者，EventArgs e)
{
如果(grdEvents.SelectedRows.Count> 0)
{
frmAddEditEvents.Selectmode ="update" ;;
frmAddEditEvents.Gender = Convert.ToString(grdEvents.SelectedRows [0] .Cells [1] .Value);
frmAddEditEvents.Division = Convert.ToString(grdEvents.SelectedRows [0] .Cells [2] .Value);
frmAddEditEvents.Genre = Convert.ToString(grdEvents.SelectedRows [0] .Cells [3] .Value);
frmAddEditEvents.Event = Convert.ToString(grdEvents.SelectedRows [0] .Cells [4] .Value);
frmAddEditEvents.Scoreeve = Convert.ToString(grdEvents.SelectedRows [0] .Cells [5] .Value);
frmAddEditEvents.Relay = Convert.ToString(grdEvents.SelectedRows [0] .Cells [6] .Value);
frmAddEditEvents.Rounds = Convert.ToInt16(grdEvents.SelectedRows [0] .Cells [7] .Value);
frmAddEditEvents.Scoreteam = Convert.ToInt16(grdEvents.SelectedRows [0] .Cells [8] .Value);
frmAddEditEvents.timeprecison = Convert.ToInt16(grdEvents.SelectedRows [0] .Cells [9] .Value);
frmAddEditEvents.Note = Convert.ToString(grdEvents.SelectedRows [0] .Cells [10] .Value);
frmAddEditEvents.Advancement = Convert.ToInt16(grdEvents.SelectedRows [0] .Cells [11] .Value);
frmAddEditEvents obj =新的frmAddEditEvents();
obj.ShowDialog();
返回；

推荐答案
您的所有控件都可访问另一个页面吗?我认为不是，因为默认情况下所有控件都是私有的.因此您需要将所有控件的属性设置为public，然后尝试访问它.
希望它能工作.
Are your all controls accessable to another page? I think not, becouse all controls are private by default. so you need to set the properties of your all controls as public then try to access it.
hope it will work.
