I am new in C# and I want to display specific rows in GridView. I could do this but I could not update it. My code:
private void bindGridView()
{
myContextDataContext context = new myContextDataContext();
var q2 = from p in context.employees
where p.check_is_mngr == 1
select p;
employeeDataGridView.DataSource = q2;
}
I called bindgridview() in bossAcc_Load function.In my form,I have add_new button and save button. This is save button function:
private void button5_Click(object sender, EventArgs e)
{
this.Validate();
this.employeeBindingSource.EndEdit();
this.tableAdapterManager.UpdateAll(this.my_proDataSet);
}
But when I click save button,didn't update data.What should I do?
Try this,
var q2 = from p in context.employees
where p.check_is_mngr == 1
select p;
employeeDataGridView.DataSource = null;
employeeDataGridView.DataSource = q2 ;
