The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

View 4 RepliesI am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for.Is there a way to edit columns and rows manually ?This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.

I have a user control that contains a search value text box a button, and a datagridview to display what the data adapter found. In the data set designer, I have an ODBC connection to a table, with two SQL queries defined FillByCustomerName(NAME), and FillByCustomerNumber(CUSTOMER_NUMBER). If I preview the data in the designer, I see the data expected. The datagridview doesn't show any data. The functions PopulateGridByName and PopulateGridByNumber do the work. I've tried adding a dgCustomer.show statement, The form that calls the user control has no codebehind code, and throws no errors.

View 3 RepliesI'm using Visual Basic Express 2008 in Windows 7(64-Bit). I've added a datasource to my project and dragged a table from Data Sources onto my form. It automatically created a DataViewGrid and placed this statement in my form load event:
Me.BillsTableAdapter.Fill(Me.DoBills_2009DataSet.Bills)
The DataGridView shows all the correct fields/columns. The .DataSource property for the DataGridView is set to the automatically created BillsBindingSource. When I preview the BillsTableAdapter, the data appears. But data does not appear when I run the app. The datagridview is empty. When I build the app and run the executable, I get a Microsoft .NET Framework error message that says: "Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click Quit, the applicaiton will close immediately. The 'Microsoft .ACE.OELDB.12.0' provider is not registered on the local machine." If I click "Continue" I get my form with an empty DataGridView. What am I missing to get the data to display in the grid at run time? Oh, and I've also tried using the DataGridView in C# and I get the same problem.

I'm writing a program for my algebra students to practice integers.Stuff like....
3-6
-4 + (-5)
3(-4)
-15 � 3
etc.
I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.

View 3 RepliesI fill the DGV by looping through a dataset and adding a DGV row for each datarow. After this the DGV.RowCount = DataSet.Rows.Count. Funny thing is that the DGV shows only a part of it (19 of 2448 in my example). After some testing I figured out that the rows show up if I change the Window size a bit.So now I use a work-around by including the following code after I've filled the DGV:[code]

This is a simple one, but I haven't seen a way to do it. I have a DataGridView that is bound to a Sql-Server database, and it works fine. The only thing I'd like to add is the row # at the beginning of every row. Yes, I COULD set the first column as "RowNUm" and maintain it that way, but it seems that having the row # on each row should be a feature already provided to us. So, is there a way to have the DataGridView display a row number for each row?
