What is preventing Combobox SelectedValue from setting?

Time:05-10

I have several comboboxes, all similar code and only one, CustomerSelector.SelectedValue, is not working. I have even tried setting the value like this: CustomerSelector.SelectedValue=32.

This Method is for loading all the Project info to the form and is called in the form Load event. The data seems to load fine, I have even loaded 'id' to the DisplayMember to verify.

Any ideas what is preventing SelectedValue from setting?

        void loadProjectInfo()
        {
            if (isProjectInfoLoaded == false)
            {

CodePudding user response:

The problem ended up being with the database, specifically the id field of s1_customer. For some reason it had the 'unsigned' attribute. When that was removed, everything worked as expected.
