Drag and Drop in datagridview

[meetarun007]

Hi to all,

I'm creating an application in which the form contains one datagridview and 20 pictureboxes.
When the DGV is populated, the user will drag a row from DGV and drop in any one of the pictureboxes.
The picturebox should able evaluate a column value(say column 1) from the dropping row and according to that it should change its picture.
Can anybody have an idea how to implement this...

Thnx in advance...

Assuming that column1 contains a path to the picture.
Here's what you can do.
First change the property AllowDragDrop to True for all the pictureboxes.
Then add this code:

Dim bMouseIsDown As Boolean = False
    Private Sub DataGridView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseDown
        If e.Button = Windows.Forms.MouseButtons.Left Then
            bMouseIsDown = True
        End If
    End Sub

    Private Sub DataGridView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseMove
        If DataGridView1.SelectedRows.Count > 0 Then
            If bMouseIsDown Then
                Dim path As String = DataGridView1.SelectedRows(0).Cells(1).Value
                DataGridView1.DoDragDrop(path, DragDropEffects.Copy)
            End If
        End If
    End Sub

'Repeat these two for all the pictureboxes
    Private Sub PictureBox1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles PictureBox1.DragEnter
        If e.Data.GetDataPresent(DataFormats.StringFormat) Then
            e.Effect = DragDropEffects.Copy
        End If
    End Sub

    Private Sub PictureBox1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles PictureBox1.DragDrop
        Dim path As String = DirectCast(e.Data.GetData(DataFormats.StringFormat), String)
        Dim stream As New IO.FileStream(path, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
        Dim img As Image = Image.FromStream(stream)
        PictureBox1.Image = img
    End Sub
