Problem with ComboBoxI'll try to explain the process I'm following, I'm new to this so I'm triying the easy way first, probably the lasyest too! I created a new Project, drag in to it a SQLConnection, configured, dragged an Dataadapter per each table I need it, then generated the dataset, after that, I stablished the relations between tables, then, went over to the datasources, choose the parent datasource and clicked on the + sign, it displayed me every field on that table as well as the related tables, until here everything goes fine, after that I change the the way I want the controls to be displayed from datagrid to form then drag/drop the source over the form and run the form, everything is fine until here, here's the little problem, I have a field called 'empid' wich is supposed to be a comboBox, I click over it and it displays nothing, I went back and stablish a datasource for it, value to display, etc, etc then, run the form again and it does display the numbers but when I start going over them it begins to change everyvalue on the combobox, per example, when the form is ran for the first time it displays the values 1001, 1002 and 1003, then while it's running I choose the diferent values and it displays them right but then when I click on the combobox there's number 1, choose a different value then when I go back it's showing a number 3 but numbers 1001 and 1002 are gone, I close the form and run it again and the numbers show fine again. Hope I explained myself, if there's any advice on what it is what I am doing wrong please let me know, thanks in advance! JJGarcia,
You have tried to explain yourself, but there are thousands of implementations of a combobox in a datagrid (It is not standard in a datagrid). That makes it difficult to help you with this. As you would use a DataGridView, than it would probably be easier to help, but the later is Net 2.0 and I assume that you use Net 1.x.

like to be able to do a search on the detail form and as I find the searched record on the combobox(be able to search or just choose a record from the list) the detail and datagrid will display me the record, as I mentioned, I have the fields already related, I tried with the datagrid view but as I am totally new to this programming world I wasn't able to make it work for me the way I wanted, I mean, i do was displaying the records but when I was modifiying the records it wont save the changes, the instruction i'm using for save any changes is [sqldataadapter.update(datataset, "my_table")]. In resume, what I need to do is to be able to use the combobox as a lookup device but the way I have configure it right now(i'm using the RAD way...!) seems no to be working, it does display the records but as I choose them the number on the combobox changes to a number that I don't know where is getting it from. By the way, another question, how do I change the name of the fields that are being displayed on the datagrid beacuse right now they are displaying the name that's on the table so it is a weird name. thanks in advance for your help JJGarcia Cor Ligthert [MVP] wrote: Show quoteHide quote > JJGarcia, > > You have tried to explain yourself, but there are thousands of > implementations of a combobox in a datagrid (It is not standard in a > datagrid).

Maybe I should ask my question more expliciet because you did not answer that. What VB version are you using and what complex data control, I am in doubt that it is a datagrid as you wrote?
