Reading from Comboboxes on a datagrid view (C++/CLI - Windows Forms App in VS2008) [modified]

Ger Hayden

I have my filtered combo boxes working in a datagridview thanks to a Linda Liu sample. Now when I enter a row I want to see the data from a row in a sequence of text boxes below the grid - but for the combo boxes I only see the index, when I would prefer to see the information e.g. route description. Here is a cutdown version of From1.h:

namespace DataGridViewComboEx5 {

using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Collections::Generic;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::IO;

public ref class Form1 : public System::Windows::Forms::Form
{
public:
	Form1(void)
	{
		InitializeComponent();
		//
		//TODO: Add the constructor code here
		//
	}

protected:
	/// <summary>
	/// Clean up any resources being used.
	/// </summary>
	~Form1()
	{
		if (components)
		{
			delete components;
		}
	}

When you have code like this, please wrap the block of code in a <pre> </pre> tags. It makes it easier to read.

Done - wasn't aware of them - and I've chopped out much of the autogenerated code. Ger

See point 7 in the Forum Guidelines[^].

Just say 'NO' to evaluated arguments for diadic functions! Ash
