manually adding text from textbox to a datagrid on button click

Question

I created static columns called "Student Name" & "Village" using XAML as below:

XML

<my:DataGrid.Columns >
      <my:DataGridTextColumn Header="Student Name" Width="200">
      </my:DataGridTextColumn>
      <my:DataGridTextColumn Header="Village" Width="200">
      </my:DataGridTextColumn>
</my:DataGrid.Columns>

Trying to add text from textbox using code under a button:

VB

Dim row1() As String = {TextBox2.Text.ToString, TextBox3.Text.ToString}
DataGrid1.Items.Add(row1)

Rows are added but with no text.
What could be the problem?

Try this

Create a structure

VB

Public Structure MyData
       Public Property id() As Integer
           Get
               Return m_id
           End Get
           Set(value As Integer)
               m_id = value
           End Set
       End Property
       Private m_id As Integer
       Public Property title() As String
           Get
               Return m_title
           End Get
           Set(value As String)
               m_title = value
           End Set
       End Property
       Private m_title As String
   End Structure

then in your button click event use the following

VB

Dim col1 As New DataGridTextColumn()
  Dim col2 As New DataGridTextColumn()

  DataGrid1.Columns.Add(col1)
  DataGrid1.Columns.Add(col2)

  col1.Binding = New Binding("id")
  col2.Binding = New Binding("title")

  col1.Header = "ID"
  col2.Header = "title"


  DataGrid1.Items.Add(New MyData() With { _
    .id = 1, _
    .title = "Test"
  })

its a rough bit of code but should help you move forward

Hi braop, I have some ideas.

First: You can use a DataTable created manually as @petermahon explained.

Second: If you want to add custom text directly in your control you cannot use DataGridTextColumn because this Property expects some DataBinding. You can use a DataGridTemplateColumn with a TextBlock inside it and then you can add text from your XAML or C#.

Let me know.

Best regards.
