Question

我有一个带有编辑/更新命令按钮的gridview。我正在使用下拉菜单为gridview数据源（ds2）设置select命令，如下所示。

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Try
 If ddFilter.SelectedValue = "Title" Then ds2.SelectCommand = "SELECT * FROM [contentStore] WHERE ([Title] LIKE '%' + @Title + '%') order by [Title] asc"
 If ddFilter.SelectedValue = "URL" Then ds2.SelectCommand = "SELECT * FROM [contentStore] WHERE ([URL] LIKE '%' + @Title + '%') order by [URL] asc"
 If ddFilter.SelectedValue = "ID" Then ds2.SelectCommand = "SELECT * FROM [contentStore] WHERE ([ID] LIKE '%' + @Title + '%') order by [ID] asc"
 GridView1.DataBind()
Catch ex As Exception
 lblFilter.Text = "<h3>Filter Issue</h3>" & ex.ToString
 End Try
End Sub

问题是当我使用编辑/更新组合时，记录正确更新，但gridview不再绑定自身。如果我再次按下按钮，则gridview会反弹，显示预期的更新数据。

我的问题是如何在更新

后让Gridview自行绑定

没有看到你的代码，我猜你需要在命令逻辑中复制按钮点击处理程序中的逻辑，以便SQL再次执行和绑定网格，如下所示：

Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)
    If e.CommandName = "Edit" Then
        ' Do logic here

        If ddFilter.SelectedValue = "Title" Then 
            ds2.SelectCommand = "SELECT * FROM [contentStore] WHERE ([Title] LIKE '%' + @Title + '%') order by [Title] asc"
        End If

        If ddFilter.SelectedValue = "URL" Then 
            ds2.SelectCommand = "SELECT * FROM [contentStore] WHERE ([URL] LIKE '%' + @Title + '%') order by [URL] asc"
        End If

        If ddFilter.SelectedValue = "ID" Then 
            ds2.SelectCommand = "SELECT * FROM [contentStore] WHERE ([ID] LIKE '%' + @Title + '%') order by [ID] asc"
        End If

        GridView1.DataBind()
    End If
End Sub

更新后Gridview没有绑定
