[英]How to get refreshed datagrid realtime on C#?
如何在網格上自動選擇? 我創建了計時器,但計時器不保存網格選擇。 例如,當我選擇網格的第三個索引時,然后在5秒后,它選擇了第一個網格索引。 所以我在這里需要其他解決方案。
private void formList_Load(object sender, EventArgs e)
{
BindingSource bs = new BindingSource();
DataTable _dt =_myFunction.Select_New_Inserted_Info(_lDataParameter).Tables[0];
bs.DataSource = _dt;
gridControl1.DataSource = bs;
timer1.Interval = 5000;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
BindingSource bs = new BindingSource();
DataTable _dt =_myFunction.Select_New_Inserted_Info(_lDataParameter).Tables[0];
bs.DataSource = _dt;
gridControl1.DataSource = bs;
}
bs.Current;
System.Windows.Forms.Timer

'事件中。 編輯
選擇指針由BindingSource處理。 因此,您必須將BindingSource放在函數之外。您的代碼將如下所示:
BindingSource bs = new BindingSource();
private DataTable GetDataTable()
{
//Please consider checking the populating data function from errors, or post your code to help you with.
DataTable dt =_myFunction.Select_New_Inserted_Info(_lDataParameter).Tables[0];
return dt;
}
private void formList_Load(object sender, EventArgs e)
{
DataTable _dt = GetDataTable();
bs.DataSource = _dt;
gridControl1.DataSource = bs;
timer1.Interval = 5000;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
DataTable _dt = GetDataTable();
bs.DataSource = _dt;
gridControl1.DataSource = bs;
}
