The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

How to refresh a DataGridView after database Update.

Asked by megnin in Microsoft Visual Basic.Net, MS SQL Server, Visual Studio

Tags: datagridview, refresh, update

How do you refresh a DataGridView with the current contents of the database after you do an UPDATE?


Private Sub btnUpdatePosition_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdatePosition.Click
        Me.Validate()
        Me.ApplicantsBindingSource.EndEdit()
        Dim rowsAffected As Integer = 0
        rowsAffected = Me.ApplicantsTableAdapter.Update(Me.SYEP2007DataSet.Applicants)
        MessageBox.Show(rowsAffected.ToString + " Rows were affected")

        Dim con As New SqlConnection
        Dim cmd As SqlCommand = New SqlCommand("dbo.spUpdate_JobTitles_PositionsAvailable", con)
        con.ConnectionString = "workingConnectionString"
        cmd.Connection = con
        cmd.CommandType = CommandType.StoredProcedure
        con.Open()
        cmd.ExecuteNonQuery()
        con.Close()

This button Updates the database, but the changes are not reflected in the DataGridView, JobTitlesDataGridView, until I exit the application and run it again.
I've searched the web for nearly a week now and none of the solutions work.  Most give me an error  right from the beginning.  I'm using VS2005, VB.NET, SQL Server 2000.

The DataSource for the DataGridView is JobTitlesBindingSource
