Hi.

I would like to ask, how to display selected item from datagrid to textbox? I'm using vb.net. I thought the codes for winform and wpf are the same...

i tried using this code:

Private Sub dgv_admin_MouseLeftButtonDown(sender As Object, e As MouseButtonEventArgs) Handles dgv_admin.MouseLeftButtonDown


Dim i As Integer
       i = dgstudents.CurrentRow.Index

       Lblid.Text = dgstudents.Item(0, i).Value
       TxtLname.Text = dgstudents.Item(1, i).Value
       TxtFname.Text = dgstudents.Item(2, i).Value


   End Sub

但文本框中没有任何内容。

but nothing is seen on the textboxes.

推荐答案

像Pheonyx提到的那样，使用一些属性创建viewModel，它将绑定到您的视图。当您想要在文本框中显示数据时，只需将created属性设置为您的值，例如：

Like Pheonyx mentioned, create viewModel, with some property, which will be binding to your view. When you would like to show data in textbox, just set created property to your value like :

createdProperty = dgstudents.Item(1, i).Value

并通过绑定它将显示在您的视图中。

and via binding it will be shown in your view.
