I've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.

When I update a record at table [Product] with the integer that stands for [Supplier Name] from joined table [Suppliers], this does not appear in my datagridview. Instead, I have to reload the table to dataset to make it visible. What about datarelation? Is it better that loading a joined table over the dataset? Note that I have never dealed with datarelations before.. How can I make a datagrid column to show "Supplier Name" instead of recordID that represents this supplier?

I'm trying to make my datagrids datasource change when you select a particular item from a drop down menu but all I get is blank cells! any ideas? I don't think it is changing the colums property automatically either.
If chooseType.Text = "Add / Edit Players" Then
updateDB.DataSource = PlayersBindingSource

I am filtering a dataview which is used for a datagrids datasource.At runtime when I apply the filters (using Checkboxes to determine the RowFilter text) I get an additional blank row at the top of my grid. This is then treated like a row & is filtered out with other rows that don't fit the filter criteria but comes back when I remove the filter. Basically, its part of the underlying DAtaview it seems. It's not persisited to database but I can't seem to get rid of it when I'm filtering.

It's my first time playing with the DataGridView properly and I've hit a little snag...I need to display data in a DataGridView for ease of viewing, and I have a list of all the data. It's a list (of a structure), and I've got no idea how to do this. I can set the datasource as the list, but that doesn't work. I've read up on the topic but don't really understand. Am I forced to use classes not structures in this instance?

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.

I'm trying to assign a datasource to a ComboBox control during runtime. When I do so, I get the attached message. Here is my
cmbAddressDesc.DataSource = dbDataSet4.tblAddressCodes.addrDescColumn
dbDataSet4 is a typed dataset. I want to learn how to use an Interface. The error message is suggesting using an IList. How would I do this. I'm having trouble finding good documentation on this.

If I used a generic list Class to hold data objects that I am pulling from SQL Server using Linq to sql to populate a datagridview would I need to make any modifications to the datagridview control to accomodate multiple columns or would I need to make any modifications to the generic list class to accomodate the multiple columns in a row that is typical of a record in SQL Server? And one more thing which I believe is the easy part. To bind the list to a datagrid view would I just use the datasource property of the datagridview control.

I have a form where I have to use control arrays to create a multiple input form i.e. rather than processing one transaction at a time up to 16 transactions must be processed. The following really havent given me much problems at this moment labels and textboxes. I use a for construct to create all the controls including a combobox. This is where my question comes in this form combobox has to be linked to a table in a database. But furthermore and this is where it gets complicated for me anyway each seperate combobox must move independly if i select row 5 in the table in combobox 4 combobox 5 which is havent touched should still be on row 1. How do I accomplish this. I'm using a webservice. I have tried passing a loaded dataset . The code that loaded the dataset is as follows
Dim DSInfo As New Project1.localhost4.AccInfo
DSInfo.Credentials = System.Net.CredentialCache.DefaultCredentials
InformationData.Merge(DSInfo.GetBusinessJournals)
[Code].....
this code doesnt however provide a link to the table equallly creating a dataset in the combobox method ,loading it and then setting it as datasource also provides no link. I know i'm missing something.

I have a list of customers (over 50k) that I am trying to change the way my users search and interact. Presently, they fill in parts of a first name, last name, home phone field(s) and then click a button and it searches and presents a listview list to the user for selection of the one they are trying to find. Fairly straight forward behind the scenes with a customers object making the call to the sql server on the network and returning customer objects as indicated. I want to add a datagridview control and display all customers and then have a textbox for the user to type their selection into and have the datagridview update accordingly.
I want the filter to be dynamic as the user is typing. What I have so far is the datagrid loaded with data and the text box. I also have a stored procedure that takes a string(the text box) and returns the customers collection object as the "new" datasource. But as you are guessing, that is to many calls to the database over the network. Just not very efficient. Once I have the original collection object, how can I filter it dynamically in memory as the user inputs characters into the textbox.

I need to create a user control which can be used in my all projects. I have created a user control with a TextBox Control and a ListBox Control. My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.
