0	The simple reason for this is that ToolStripMenuItem is not of string type so it is not getting converted. Probably you need to instantiate ToolStripMenuItem by passing the ComboBox1.SelectedItem or ComboBox1.SelectedItem.Value and then try to cast it.

0	You may try this code: private void BuildMenuItems() { ToolStripMenuItem[] items = new ToolStripMenuItem[2]; // You would obviously calculate this value at runtime.your splited string length goes here for (int i = 0; i < items.Length; i++) { items[i] = new ToolStripMenuItem(); items[i].Name = "dynamicItem" + i.ToString(); //You have to set your string value here items[i].Tag = "specialDataHere"; items[i].Text = "Visible Menu Text Here"; items[i].Click += new EventHandler(MenuItemClickHandler); } myMenu.DropDownItems.AddRange(items); } private void MenuItemClickHandler(object sender, EventArgs e) { ToolStripMenuItem clickedItem = (ToolStripMenuItem)sender; // Take some action based on the data in clickedItem } DOT NET Rashedbin, if this helps please login to Mark As Answer. \| Alert Moderator

You may try this code:

private void BuildMenuItems()
{
ToolStripMenuItem[] items = new ToolStripMenuItem[2]; // You would obviously calculate this value at runtime.your splited string length goes here
for (int i = 0; i < items.Length; i++)
{
items[i] = new ToolStripMenuItem();
items[i].Name = "dynamicItem" + i.ToString(); //You have to set your string value here
items[i].Tag = "specialDataHere";
items[i].Text = "Visible Menu Text Here";
items[i].Click += new EventHandler(MenuItemClickHandler);
}

myMenu.DropDownItems.AddRange(items);
}

private void MenuItemClickHandler(object sender, EventArgs e)
{
ToolStripMenuItem clickedItem = (ToolStripMenuItem)sender;
// Take some action based on the data in clickedItem
}
