Question

Please I really need help on this one… I have 2 Forms Form1 and Form2. In Form2 I Filter the DGV by Textboxchanged event

TBC Code

Dim dvSection As DataView
    Dim tableAdapter As New testDataSetTableAdapters.testingTableAdapter
    Dim ds As New testDataSet
    dv.Table = TestDataSet.testing
    dv.RowFilter = "CONVERT(TransactionID, System.String) LIKE '%" & TextBox1.Text & "%'"
    TestingDataGridView.DataSource = dv

I return the filtered data by assigning the dv as the new DataSource for Form1 DGV.

This Code Works

    Form1.TestingDataGridView1.DataSource = dv

Here in my question, in Form1 (with filtered data). I want to Edit the data in the DGV and then Update my MySql Table "testing". I am really confused about this cause I’ve never done this before. I usually Update my DGV and MySql Table by using the ff codes. How ever in this situation the ff codes doesn’t work.

 If MsgBox("Save Changes Made in this Cell?", MsgBoxStyle.YesNo, MsgBoxStyle.Exclamation) = DialogResult.Yes Then
        Me.Validate()
        Me.TestingBindingSource.EndEdit()
        Me.TestingTableAdapter.Update(Me.TestDataSet.testing)

    End If

I am really confused now, A little help would be really nice. Please and Thank You.

Answer 1

I’m finally able to update the data view now… Let me post my codes here for future reference just in case someone also needs help. this is a sample project so I didn’t go much into the codes and went directly to how I solved it.

Form1 has Datagridview(databound), 1 button "Form2"

Codes for Form 1

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        `TODO: This line of code loads data into the TestDataSet.testing table. You can move, or remove it, as needed.`

        Me.TestingTableAdapter.Fill(Me.TestDataSet.testing)

    End Sub


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form2.Show()
        ' Me.Hide()'
        Me.TestingBindingSource.DataSource = TestDataSet
        Me.TestingTableAdapter.Dispose()
        Me.TestingTableAdapter.Fill(Me.TestDataSet.testing)

    End Sub

    Private Sub TestingDataGridView1_CellEndEdit(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles TestingDataGridView1.CellEndEdit

        If MsgBox("Save Changes Made in this Cell?", MsgBoxStyle.YesNo, MsgBoxStyle.Exclamation) = DialogResult.Yes Then
            Me.Validate()
            Form2.TestingBindingSource().EndEdit()
            Me.TestingTableAdapter.Update(Me.TestDataSet.testing)

        End If
    End Sub
End Class

Form2 has DGV (databound), 2Buttons, "Return", "Save", and a textbox

 Private Sub TestingBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TestingBindingNavigatorSaveItem.Click
        Me.Validate()
        Me.TestingBindingSource.EndEdit()
        Me.TableAdapterManager.UpdateAll(Me.TestDataSet)

    End Sub

    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the TestDataSet.testing table. You can move, or remove it, as needed.'
        Me.TestingTableAdapter.Fill(Me.TestDataSet.testing)

    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

        Dim tableAdapter As New testDataSetTableAdapters.testingTableAdapter
        Dim ds As New testDataSet

        dv.Table = TestDataSet.testing
        dv.RowFilter = "CONVERT(TransactionID, System.String) LIKE '%" & TextBox1.Text & "%'"
        TestingDataGridView.DataSource = dv
        Form1.TestingDataGridView1.DataSource = dv

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Form1.Show()
        Me.Hide()

        Me.TestingTableAdapter.Dispose()
        Me.TestingTableAdapter.Fill(Me.TestDataSet.testing)
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        If MsgBox("Save Changes Made in this Cell?", MsgBoxStyle.YesNo, MsgBoxStyle.Exclamation) = DialogResult.Yes Then
            Me.Validate()
            Me.TestingBindingSource.EndEdit()
            Me.TestingTableAdapter.Update(Me.TestDataSet.testing)

        End If
    End Sub
