    If you want to put it in a button here is the code 🙂 (VISUAL STUDIO 2013)
    copied the loaddata() and edi the sql/query

    Private Sub btnSearch_Click(sender As Object, e As EventArgs) Handles btnSearch.Click

    mysqlconn = New MySqlConnection
    mysqlconn.ConnectionString = "server=localhost;userid=root;password=;database=dbdata"

    Dim dtAdapter As New MySqlDataAdapter
    Dim dt As New DataTable
    Dim bsource As New BindingSource

    Try
    mysqlconn.Open()
    Dim sql As String
    sql = "SELECT * FROM dbdata.edata WHERE ename LIKE '%" + txtSearch.Text + "%' "
    cmd = New MySqlCommand(sql, mysqlconn)

    dtAdapter.SelectCommand = cmd
    dtAdapter.Fill(dt)
    bsource.DataSource = dt
    DataGridView1.DataSource = bsource
    dtAdapter.Update(dt)

    mysqlconn.Close()

    Catch ex As MySqlException
    MessageBox.Show(ex.Message)
    Finally

    I wonder that when I try the searching, it gives double values of all the items on the database, like it had inputted the given data twice during insert into-event.. What's the issue?

    My one doesn't work. I will begin typing a search and then the values in the data grid view will disappear and it will show just the grey background and stay like that until I close the whole program. Help please!

    Seems there isn't much feedback coming from the owner of this Tutorial. If you need help here, I will do my best, just ask.

    I have automated this to load any table from any database using a combobox. It is working like a dream come true. Thanks for the tutorial. This is going to make me lots of money.

    After following step by step your tutorials, kind sir, I have encountered a rather uncanny error. It appears that, after deleting the line "Dim dbDataSet As New DataTable" and declaring it as a global variable, if you press the "Load Table" button, it stores the table multiple times. I do not know for sure if this is the main issue, but after copying the line back to it's original place, everything seems to work out pretty good 🙂 Thank you for those helpfull tutorials, once again and don't take my commentary as a malitious one, please. Just wanted to point out a possible error 🙂 Have a nice day!
