Dynamically adding menuStrip items

问题:

so I have a problem with dynamically adding items to menuStrip. I mean I know how to add items to it, but I dont have any idea how to make Click handler to those dynamically added items.

for(int i = 0; i < grupiuKiekis; i++)
    {
        row2 = mysql_fetch_row(result2);
        System::String^ grupesName = gcnew String(row2[1]);
        pasirinktiGrupęToolStripMenuItem->DropDownItems->Add(grupesName);
    }

Please show me the right way to do it.

回答1:

The Add method has several overloads. You could use the overload that allows you to specify an EventHandler explicitly, or you could construct a ToolStripItem, set up a click handler on that, and then add the ToolStripItem.

Edit

Here's basically what you want to do:

for(int i = 0; i < grupiuKiekis; i++)
{
    row2 = mysql_fetch_row(result2);
    System::String^ grupesName = gcnew String(row2[1]);
    ToolStripItem^ item = gcnew ToolStripItem();
    item->Text = grupesName;
    item->Click += gcnew EventHandler(this, &Form1::clickHander);
    pasirinktiGrupęToolStripMenuItem->DropDownItems->Add(item);
}

void clickHander(Object^ sender, EventArgs^ e)
{
    ToolStripItem^ item = (ToolStripItem^) sender;
    System::String^ grupesName = item->Text;
    // Do what you need to do.
}
