View 1 RepliesI have defined a datagrid which has combobox in one of the columns, is there anyway to modify the datasource of the combobox (the source of the list) at run time?

View 1 RepliesWhen 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?
View 2 RepliesI'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.

View 2 RepliesIt'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?
View 1 RepliesI am trying to build a DataTable to populate a DataGrid in VB.NET. The columns will be the username and then question from an exam. Each row will be the answers by user for each question.
So it would look something like this:
Username | What is your favorite color? | What is your favorite book?

That works great and gives me a table that has the needed columns, but I am stuck as to how and get each users answer and put it under the appropriate column.
I tried adding rows in the same loop, but that just adds all of the answers under the first column.
Employee emp = new Employee();
comHandledBySQt.DataSource = emp.GetDataFromTable("1");
comHandledBySQt.DisplayMember = "FirstName";
The above code displays drop list of employees first names in a combo box. I want first name and last name to be displayed. How can i do it?I tried to include two columns FirstName and LastName as below but didn't work.
comHandledBySQt.DisplayMember = "FirstName" + " " + "LastName";
I am currently building a system in SQL Server 2005.
I have a table that holds information about certain insurance schemes such as overheads and other things. These values will change occasionally and currently I administer the database straight through the management Studio.
I would like to build a simple interface that will allow my colleagues to change these values by selecting the company in a dropdown and the current values will populate. They can then edit these values and submit them to the database.
Is this possible in the current Visual Studio supplied with SQL Server 2005 or do I need to get another product.
I use vb.net and windows form and sqlserver

I have an application in which I have two text boxes in which I enter name and age, after I enter the name and age then I click the Add button when I click the add button then the Name and the age should be displayed on the Datagrid contol in the same application. But the data should not get saved in the Database, it should just show the data on the Datagrid contol. And they have told me that its mandatory that I have to use the DataTable object.
And when i click the Commit Changes then only the data should get saved to the Data base...This i can do .
I have a database and a dataset as the image shows in the link, how would i add the values of the colums "amount1" and "amount2" for every row and entry as the user make entries to be automatically displayed in the "total" column. Meaning that every time values are entered in those amount columns, they will be added and the total displayed in the "Total" column.
