在按钮单击时手动将文本框中的文本添加到数据网格 [英] manually adding text from textbox to a datagrid on button click

问题描述

我创建了名为学生姓名的静态列& Village 使用 XAML ，如下所示：

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

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

尝试使用按钮下的代码从文本框添加文本：

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

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

已添加行但没有tex t。

可能是什么问题？



格式化的代码块[/ Edit]

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

推荐答案

试试这个



创建一个结构

Try this

Create a structure

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

然后在你的按钮点击事件中使用以下

then in your button click event use the following

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"
  })

它代码粗略但可以帮助你前进

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

你好braop，我有一些想法。



第一：你可以使用手动创建的DataTable，如@petermahon所解释的那样。



第二：如果要直接在控件中添加自定义文本，则不能使用 DataGridTextColumn ，因为此属性需要一些DataBinding。您可以在其中使用带有TextBlock的 DataGridTemplateColumn ，然后您可以添加XAML或C＃中的文本。



告诉我。< br $> b $ b

祝你好运。

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.
