Jun 2, 2011
How do I display the concatenated records in my combobox? I have the following codes

If cnn.State = ConnectionState.Closed Then cnn.Open()
If rdoHS.Checked = True Then

What should I put in the DisplayMember and ValueMember? If I will not concatenation, I just use "LastName" and "IDNO" in my DisplayMember and ValueMember respectively then records get to display in my combo.

On formload I checked the value of the option button and assign either "HS" or "ELEM" like [code]...

On the form load event i want to populate my ComboBox1 to display unique items directly from the DB. For that i have set the DataSource property of the ComboBox1 to the selected field. On the ComboBox1_SelectionChangeCommitted event i have set the filter for the DataSource which is working fine.
Now when i select an item from the ComboBox1 i get the filtered result in DataGridView but when i again drop down the combobox i see nothing other than the last selected item. Why is this happening? Is there a better way of populating ComboBox with the items directly from DB with default selected value as null?

I can't figure out whats the best code for deleting a record from the database using combobox in VB.Net. the navigation of my combobox works fine.. when i click the dropdownlist of my combobox and select another name, the selected row on my grid also displays records the same as what is seen in my navigation boxes.... but the problem is when i am going to delete the records.
Here's a photo of my sample program :
The selected row on my grid is the records that i am going to delete.
Here is the photo after clicking the delete button. It delete the entire selected rows except the selected column Name, instead the first row column "Name" record is deleted and the second row column "Name" replace to it.
Here is the code for my delete button:
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.TblCreditBindingSource.RemoveCurrent()
[Code].....
I dont know what's the process of deleting should i do..

I have a form with controls on it which are binded to a table, I have records selecters and so on... Just a simple display and edit form(yes I also want to be able to edit them so...) I created this form just by dragging items from the Data sources window.
Now I want to add a combobox which has a list of titles. And here comes the difficult part: When I select a title in the combobox, all the other controls show the matching info(matching to the title), in other words the datatable which is attached/binded to the controls must move to the right record. I have added a query to the combobox , which has two columns: ID and Title. the displaymember is Title and the Valuemember is ID. So I must look in the datatable for the right ID.

I currently have a sql database linked to vb.net and I'm populating the comboboxes using SELECT statements. However, I'm getting duplicate records in the comboboxes.I have my database setup as 1 project to many submittals and 1 submittal to many items.
I have 3 projects in my sample dataset and I'll recieve 3 duplicate submittals and 3 duplicate items.
If I have 6 projects in my sample dataset than I'll get 6 duplicate submittals and 6 duplicate items.
I've tried adding distinct to my SQL statement, but that didn't do anything. Is there any reason why its showing as many duplicates as I have projects?

Essentially, what I'm trying to do is build a table of data dynamically on a page that is 3 columns wide by however many long.Working off a Classic ASP example, I've gotten as far as trying that, but not all the records display and they still render on the page as rows instead of columns.[code]I'm not overly certain how to do it, and I'm fairly sure it's probably really simple to do on a view page.My other option is to set a finite amount of records to be created and build the table on the page from that, but I'd much rather do it dynamically.I guess also an alternative option would be to use a repeater control? Though I don't know if this is a control that will work with MVC.
