I have a combo box that is bound to a table in a dataset. When I add, modify or delete a record in the dataset, i need that to be reflected in the combo box. I use the generated functions of the dataset. The database itself changes accordingly but not the bound control. I am using Visual C++ in VS 2005. All the databinding was done with drag and drop in the visual designer.
Thanks in advance for your help
this is the code that i am using. most of it was generated when i built the form.
private: System::Windows::Forms::BindingSource^ companiesBindingSource1;
this->companiesBindingSource1 = (gcnew System::Windows::Forms::BindingSource(this->components));
(cli::safe_cast<System::ComponentModel::ISupportInitialize^ >(this->companiesBindingSource1))->BeginInit();
//sets up binding source
this->companiesBindingSource1->DataMember = L"Companies";
this->companiesBindingSource1->DataSource = this->CallSheetDataSet;
//binds here
this->deleteRec2->DataSource = this->companiesBindingSource1;
this->deleteRec2->DisplayMember = L"Name";
this->deleteRec2->FormattingEnabled = true;
this->deleteRec2->Location = System::Drawing::Point(115, 52);
this->deleteRec2->Name = L"deleteRec2";
this->deleteRec2->Size = System::Drawing::Size(197, 21);
this->deleteRec2->TabIndex = 11;
this->deleteRec2->SelectedIndexChanged += gcnew System::EventHandler(this, &Form1::comboBox10_SelectedIndexChanged);
(cli::safe_cast<System::ComponentModel::ISupportInitialize^ >(this->companiesBindingSource1))->EndInit();
//on button press deletes item selected in combobox from database
//Need to refresh data in combobox once delete is complete
private: System::Void deleteButton_Click(System::Object^ sender, System::EventArgs^ e) {
System::String^ deleteType = deleteRec1->GetItemText(deleteRec1->Items[deleteRec1->SelectedIndex]);
if(deleteType == "Company"){
this->CompaniesTableAdapter->Delete(deleteBox1->Text);
//end edit doesnt work here
this->companiesBindingSource1->EndEdit();
this->deleteRec2->DataSource = this->companiesBindingSource1;
//tried forcing refresh here, doesnt work
this->companiesBindingSource->ResetBindings(false);
this->companiesBindingSource1->ResetBindings(false);
}//if company
