Saving Data on a Form

Thomas Anderson

Hi everyone,

I have a minor problem with one of my assignments. I want my child form to show defalut values on open. When i update the data or change the existing data i want it to be saved and then when i reopen the form i want those values to be shown. To elaborate more, I have a parent form and child form. When i select an item from a combo box in parent form and click on update button, the child form opens and shows default values. And then when i change the default values and click the update button in the child form the values need to be changed. So when i close the child form and reselect the same product and click update from parent form. The new values need to be shown. I am attaching a link to my code. Please take a look

Hi Thomas,
I did few minor changes in your code and now it is working. In the application, when you update the ProductForm you are updating only the local array field

pObjBeta[sLFTwo.productCombo.SelectedIndex].productCategory = categoryCombo.SelectedItem.ToString();

which is visible only to this product page. So you have to reassign the productCategory to the main page which I have done.
Please let me know if you face any more problem.

Regards,
Raaj
