# How to get index value in combo box?

I have a [ComboBox](https://www.mindstick.com/articles/57/display-record-according-to-combobox-selection-in-csharp-dot-net) with two [values](https://www.mindstick.com/forum/327/sum-textbox-values) 'cash' and 'bank' if the [user](https://www.mindstick.com/articles/13001/multi-statement-table-valued-user-defined-function-in-sql-server) selects bank I need to enable [two controls](https://www.mindstick.com/forum/33404/delegate-classes-connection-with-two-controls-in-objective-c). I've tried below [code](https://yourviews.mindstick.com/view/85458/alan-turing-the-mastermind-behind-cracking-the-enigma-code-during-world-war-ii):

[private](https://www.mindstick.com/blog/11097/java-access-modifiers-the-public-and-the-private-modifiers) void comboBox_pay_type_SelectedIndexChanged(object sender, EventArgs e)

{

if (comboBox_bank.SelectedIndex == 1)

{

comboBox_bank.Enabled = true;

textBox_recp_no.Enabled = true;

}

}

[Problem](https://yourviews.mindstick.com/view/81399/tackling-the-problem-of-unemployment-during-corona-pandemic) is the [index](https://www.mindstick.com/blog/198/index-in-sql-server) [value](https://www.mindstick.com/articles/23219/an-optimized-description-adds-value-to-experience-and-in-turn-effectively-guest-posting-packages) is -1 for both cash and bank. Where have I made an [error](https://yourviews.mindstick.com/view/88527/fixing-quickbooks-error-4120-reinstalling-vs-repairing)?

Hi Ankita,\

You're just referencing the wrong combo box:

```
private void comboBox_pay_type_SelectedIndexChanged(object sender, EventArgs e){    if(comboBox_pay.SelectedIndex == 1)    {       
comboBox_bank.Enabled = true;       
textBox_recp_no.Enabled = true;    }}
```

You need to reference comboBox_pay here.
