I have a combo box that works great. However, I found a glitch that if the mouse wheel is hit it will throw everything into the rich text box I built. So I'm trying to disable mouse scrolling in a combo box. Thanks for any help in advance

private: System::Void part_SelectedIndexChanged(System::Object^  sender, System::EventArgs^  e) {
				 
		   if (part->Text == "AC Adapter"){
			   this->technote->Text= "S/N: " + this->SERIAL->Text +"\nP/N:\nSPARE:\nOUTPUT:\nPRONGS:\n-----------------------------------\n" + this->technote->Text;
			   this->technote->Text= "M/N: " + this->MODEL->Text +"\n" + this->technote->Text;
			   this->technote->Text= "****AC ADAPTER****\n" + this->technote->Text;}
		   else if (part->Text == "Battery"){
			   this->technote->Text= "S/N: " + this->SERIAL->Text +"\nP/N:\nCell Size:\n-----------------------------------\n" + this->technote->Text;
			   this->technote->Text= "M/N: " + this->MODEL->Text +"\n" + this->technote->Text;
			   this->technote->Text= "****BATTERY****\n" + this->technote->Text;}
		   else if (part->Text == "Wired Keyboard"){
			   this->technote->Text= "S/N: " + this->SERIAL->Text +"\nP/N:\nPort:\nGeneric Y/N:\n-----------------------------------\n" + this->technote->Text;
			   this->technote->Text= "M/N: " + this->MODEL->Text +"\n" + this->technote->Text;
			   this->technote->Text= "****WIRED KEYBOARD****\n" + this->technote->Text;}
		   else if(part->Text == "Wired Mouse"){
			   this->technote->Text= "S/N: " + this->SERIAL->Text +"\nP/N:\nPort:\nGeneric Y/N:\nOptical or Ball:\n-----------------------------------\n" + this->technote->Text;
			   this->technote->Text= "M/N: " + this->MODEL->Text +"\n" + this->technote->Text;
			   this->technote->Text= "****WIRED MOUSE****\n" + this->technote->Text;}
		   else if(part->Text == "Wireless Set"){
			   this->technote->Text= "S/N: " + this->SERIAL->Text +"\nKeyboard P/N:\nMouse P/N:\nGeneric Y/N:\n-----------------------------------\n" + this->technote->Text;
			   this->technote->Text= "M/N: " + this->MODEL->Text +"\n" + this->technote->Text;
			   this->technote->Text= "****WIRELESS SET****\n" + this->technote->Text;}

its not the best way to do it but right now i dont rem.. the stuff as its a C++ .Net ,any way a simple way.
First create two variable
1)"bool status" that will check if the dropdown list event has occured or not if yes it will become true and when the dropdown list is closed it will be false.
Now the second variable its a "int index" that stores the current index of the combo when the dropdown list closed event occures.
At last we will be checking the status if the index is changed if the status is false then the index will be restored from the index variable.
The code will be like this for example

//Our variables 
bool status; //Initialized as false
int index;   // Initialized as 0

Now in comboBox_DropDown Event it will be

status = true;//When the list is shown so that we can change the index

Now in comboBox_DropDownClosed Event it will be something

status = false; 
index = this->comboBox->SelectedIndex;

Now in comboBox_SelectedIndexChanged Event it will be

if(!status)
this->comboBox->SelectedIndex = index;

Try to find some other way to do this stuff

Good Luck
