使用日历过滤数据网格

Question

我使用带有日期格式的行列的数据网格。

这是数据网格创建代码

    dg_datos.Columns.Add("tarea", "Tarea")
    dg_datos.Columns.Add("horas", "Horas")
    dg_datos.Columns.Add("descripcion", "Descripcion")
    dg_datos.Columns.Add("fecha", "Fecha")
    dg_datos.Columns("fecha").DefaultCellStyle.Format = "dd/MM/yyyy"


    dg_datos.Rows.Add("Ada Lovelace", "1", "desc.1", "10/11/2002")
    dg_datos.Rows.Add("Rafael Nadal", "1.4", "desc.2", "11/11/1822")
    dg_datos.Rows.Add("Lewis Hamilton", "0.4", "desc.3", "19/11/1978")
    dg_datos.Rows.Add("Charles Leclerc", "5", "desc.4", "02/01/1992")
    dg_datos.Rows.Add("HOLA HOLA", "5", "desc.5", "20/04/2022 0:00:00")





    Dim table As New DataTable
    BindingSource1.DataSource = table
    dg_datos.DataSource = BindingSource1


        Private Sub Calendario_DateSelected(sender As Object, e As DateRangeEventArgs) Handles calendario.DateSelected


        BindingSource1.Filter = String.Format("fecha = #{0:M/dd/yyyy}#", calendario.SelectionStart)

    End Sub

我不知道为什么这不起作用

Answer 1

我决定只 post 一个答案以避免进一步的痛苦，尽管不能保证你不会做答案中没有的事情。无论如何，您应该像这样绑定数据：

Dim table As New DataTable

Using adapter As New SqlDataAdapter(query, connectionString)
    adapter.Fill(table)
End Using

BindingSource1.DataSource = table
DataGridView1.DataSource = BindingSource1

然后你就按照我在评论中反复告诉你的那样过滤数据：

Private Sub Calendario_DateSelected(sender As Object, e As DateRangeEventArgs) Handles calendario.DateSelected
    BindingSource1.Filter = String.Format("fecha = #{0:M/dd/yyyy}#", calendario.SelectionStart)
End Sub

使用日历过滤数据网格

Filter datagrid with calendar
