Using VB.Net

Windows application

Form (Gridview and Textbox)

GridView1

ID Name

001 Rajan
002 Sajan
103 Prathev
104 vijayan
....

Conditon

When i clicked the up and down arrow (keyboard) in the Gridview1 (id or name row), then selected cell should display in the textbox and also when i enter some numbers means, that entered number should appear in the textbox and also entered related ID or name should display in the gridview1

For Example

If i press 0, that 0 should display in the textbox, and gridview display like

ID Name

001 Rajan
002 Sajan

If i press 1, that 1 should display in the textbox, and gridview display like

ID Name

103 Prathev
104 vijayan

Tried Code for displyaing in the girdview

Dim conObjects As New ConnectionObjects
        conObjects.OpenConnection()
        Dim cmd As SqlCommand
        Dim ds As DataSet
        Dim ada As SqlDataAdapter
        cmd = New SqlCommand("Select ID, Name from employee where id like '%" & textbox1.Text & "%' ", conObjects.myConnection)
        ada = New SqlDataAdapter(cmd)
        ds = New DataSet
 开发者_开发知识库       ada.Fill(ds, "employee")
        gridview1.DataSource = ds.Tables(0)

Expected answer

-> In which gridview event i have to write a code
-> If i press up or down arrow, then selected cell should display in the textbox
-> If i enter some number or characters, that numbers or character should display in the textbox and selected related values should display in the gridview

How to do this.

You can bind your dataSource to dataGridview and TextBoxes.

Here is sample code (Add dataGridView1, TextBox1,TextBox2):

 Private Sub YourForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Dim dt As New DataTable
        dt.Columns.Add("No")
        dt.Columns.Add("Name")

        dt.Rows.Add(1, "A")
        dt.Rows.Add(2, "B")

        DataGridView1.DataSource = dt

        TextBox1.DataBindings.Add("Text", dt, "No")
        TextBox2.DataBindings.Add("Text", dt, "Name")
    End Sub
