主窗体的代码：Form1
private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
if (tabControl1.SelectedTab.Name.Contains("组呼列表"))
{
FormCallGroup FCG = new FormCallGroup(dataApplication,tabControl1.SelectedTab.Name);//我想通过重载使得切换页面的时候表格数据一直更新
FCG.loadForm();
}
}
子窗体FormCallGroup的代码
public FormCallGroup(DataApplication data,string key)
{
InitializeComponent();
dataCallGroup = data.dicCG[key];
if (FormLinker.datalinker != null)
{
for (int i = 0; i < FormLinker.datalinker.dataLinker.Count; i++)
{ datalinker.Add(FormLinker.datalinker.dataLinker[i].Linker_name); }
}
numberA = datalinker.Count;
//FormCallGroup窗体的初始化，载入一些数据和表格初始化
if (dgv_member.Rows.Count == 0)
{
for (int i = 0; i < 14; i++)
{ dgv_available.Rows.Add(new DataGridViewRow()); }
}
if (dgv_member.Rows.Count == 0)
{
for (int i = 0; i < 14; i++)
{ dgv_member.Rows.Add(new DataGridViewRow()); }
}
dgv_available.ClearSelection();
dgv_member.ClearSelection();
dgv_available.RowStateChanged += new DataGridViewRowStateChangedEventHandler(handleRowState);
loadData();

//切换页面时做的一些数据处理，让数据在原有数据的基础上更新
numberA = datalinker.Count;

}
我做的是这样的，在主窗体Form1中有一个tabcontrol里面存放着两种窗体Formlinker和FormCallGroup
其中Formlinker内的数据更新时，FormCallGroup的数据也要跟着刷新，附图
Formlinker.数字联系人=FormCallGroup.可用的+FormCallGroup.成员
然后我代码这样子写，只有当tabpage被新建出来的时候FormCallGroup.可用的表的数据才会刷新
但是我监控的时候看到表的Value是有被赋值的这是为什么
