在WinForms應(yīng)用程序中,DataGridView控件通常用于顯示和編輯數(shù)據(jù)。要實(shí)現(xiàn)DataGridView的數(shù)據(jù)共享,可以采取以下幾種方法:
使用數(shù)據(jù)源(DataSource):
DataTable sharedTable = new DataTable();
sharedTable.Columns.Add("Column1");
sharedTable.Columns.Add("Column2");
DataGridView dataGrid1 = new DataGridView();
dataGrid1.DataSource = sharedTable;
DataGridView dataGrid2 = new DataGridView();
dataGrid2.DataSource = sharedTable;
通過(guò)公共屬性或方法共享數(shù)據(jù):
public class SharedData
{
public DataTable SharedDataTable { get; set; }
public SharedData()
{
SharedDataTable = new DataTable();
SharedDataTable.Columns.Add("Column1");
SharedDataTable.Columns.Add("Column2");
}
}
// 在需要使用共享數(shù)據(jù)的類中
SharedData sharedData = new SharedData();
DataGridView dataGrid1 = new DataGridView();
dataGrid1.DataSource = sharedData.SharedDataTable;
DataGridView dataGrid2 = new DataGridView();
dataGrid2.DataSource = sharedData.SharedDataTable;
使用事件或委托實(shí)現(xiàn)數(shù)據(jù)更新:
public class SharedData
{
public DataTable SharedDataTable { get; set; }
public event Action DataChanged;
public SharedData()
{
SharedDataTable = new DataTable();
SharedDataTable.Columns.Add("Column1");
SharedDataTable.Columns.Add("Column2");
}
public void RaiseDataChanged()
{
DataChanged?.Invoke();
}
}
// 在需要使用共享數(shù)據(jù)的類中
SharedData sharedData = new SharedData();
DataGridView dataGrid1 = new DataGridView();
dataGrid1.DataSource = sharedData.SharedDataTable;
dataGrid1.CellValueChanged += (sender, e) => sharedData.RaiseDataChanged();
DataGridView dataGrid2 = new DataGridView();
dataGrid2.DataSource = sharedData.SharedDataTable;
這些方法可以根據(jù)你的具體需求進(jìn)行選擇和調(diào)整。總的來(lái)說(shuō),實(shí)現(xiàn)DataGridView的數(shù)據(jù)共享主要是通過(guò)數(shù)據(jù)源、公共屬性或方法以及事件或委托來(lái)完成的。
