Question

当程序执行时，datagridview会填充数据以及文本框（例如StockNumber，Description），当我在搜索文本框中输入单词时，datagridview会过滤匹配的单词。当我在datagridview中单击该项时，文本框没有改变它没有显示信息...

我的问题的解决方案..我需要在datagridview中点击项目时在文本框中显示信息..

Private Sub txtreg_delsrch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtreg_delsrch.TextChanged

    Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=C:\Users\sony\Documents\Visual Studio 2008\Projects\Inventory\ItemInventory.mdb")
    Dim cmd As OleDbCommand = New OleDbCommand("SELECT StockNo,Item,Description,Reference,Quantity,Unit FROM Supplies_Regular WHERE Description Like '%" & txtreg_delsrch.Text & "%'", con)
    con.Open()
    Dim myDA As OleDbDataAdapter = New OleDbDataAdapter(cmd)
    Dim myDataSet As DataSet = New DataSet()
    myDA.Fill(myDataSet, "MyTable")
    Supplies_RegularDataGridView1.DataSource = myDataSet.Tables("MyTable").DefaultView

End Sub

Answer 1

也许您可以使用BindingSource：

Dim binding = New BindingSource() 
    With { .DataSource = myDataSet.Tables("MyTable") }
Supplies_RegularDataGridView1.DataSource = binding
StockNumber_textBox1.DataBindings.Add("Text", binding, "StockNo")

最后一行只是将对象的StockNo属性绑定到TextBox.Text。

Answer 2

您可以在Grid CellClick事件中执行类似的操作。

    Dim row As Integer = e.RowIndex
    Dim col As Integer = e.ColumnIndex

    textbox.Text = grid.Item(col, row).value

datagridview到文本框绑定数据
