combo box

[pratheek]

Hi

Could someone help me please. My problem is, I have 2 comboboxes and when I select an item from the dropdown list of my 1st combobox, the items in the dropdown list of 2nd combox must change accoring to the item selected in the 1st combobox

For example if I select TLC2274 in first combobox it should show OP-1, OP-2, OP-3 in the 2nd combox and if I select LM2903 it should show OP-1, OP-2.

The items in the 1st combobox are .csv files which contain pin numbers and pin definitions of opamp. Thankyou in advance

Regards

You can use the 'Strings []' property, in a property node, to programatically define the content of a combo box.

Hi Phil_

I have a problem.....The items in my 1st combobox contains the data as in the attachment below. it is a .csv file....... in the 2nd combobox i need only o/p-1 and o/p-2 to be shown......... So in the case structure, i need to read the .csv file, compare the data and then wire it to the string[]. Is this the correct procedure ? if not could you please tell me how could i do it

That sounds reasonable to me. 

Try it out and see if it works! If it dosen't post your code so we can help.

The 'read from spreadsheet' VI in the file I/O section of the Programming pallette, would be useful to read your .csv.
