如何在vb.net(Windows应用程序)中处理gridview中的linkbutton的点击事件

Answer 1

您需要使用 DataGridView.CellClick 事件并检查您是否获得了正确的列索引。您可以通过以下步骤来完成:

Create a new Windows Forms application

Drag a DataGridView onto the screen

In the design time properties, add a column to your grid of type DataGridViewLinkColumn

Make the DataPropertyName property to "Link" (no quotes).

In your forms constructor, paste this code under the call to InitializeComponent:

哦，是的，您正在 VB.NET 中执行此操作，所以它会是:

Dim data As New DataTable()
data.Columns.Add(New DataColumn("Link", Type.GetType("System.String")))
Dim newRow As DataRow = data.NewRow()
newRow("Link") = "http://www.stackoverflow.com"
data.Rows.Add(newRow)
DataGridView1.DataSource = data

Consume the DataGridView.CellClick event

Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
    If (e.ColumnIndex = 0) Then
        Dim link As String = DataGridView1(e.ColumnIndex, e.RowIndex).Value.ToString()
        System.Diagnostics.Process.Start(link)
    End If
End Sub
