immejutsja : combobox i 2 datatimepicker
Combobox zapolnjajetsja tak:
private void FillItems(ComboBox cmb) //Combobox with batch
{
cmb.Items.Clear();
dvBatch = new DataView(this.dataSet11.Tables["Batch"]);
cmb.DataSource = dvBatch;
dvBatch.RowFilter = "StartTime >= '"+ this.dateTimePicker_fra.Value+"' AND StartTime <= '"+ this.dateTimePicker_til.Value+"' AND Status =2";
dvBatch.Sort = "Batch";
cmb.DisplayMember = "Batch";
cmb.ValueMember = "BatchID";
comboBox4.SelectedValueChanged +=new EventHandler(comboBox4_SelectedValueChanged);
} |
t.e. mi ego svjazivajem s dataset.
a teper nado pomenjat znachenije v odnom iz datatimepickerov (ili v oboih)
pri smene voznikajet owibka:
| |
Cannot modify the Items collection when the DataSource property is set.
|
t.e predlagajut otvjazat ego pri pomoschi SuspendBinding(), pomenjat dannije a potom zanovo ego zavjazat.
pomogite eto sdelat, a to moj kod emu ne nravitsja:
BindingManagerBase bm=BindingContext [this.dataSet11, "Batch"];
bm.SuspendBinding();
FillItems(comboBox4);
bm.ResumeBinding(); |
