vb.net - 如何在 c1flexgrid 中通过代码设置 DataField 属性

Question

我正在使用C1FlexGrid并将数据表设置为c1flexgrid 的数据源。现在我想通过代码将数据表字段映射到c1flexgrid的列。请告诉我该怎么做。

Answer 1

以编程方式在 C1FlexGrid 上创建列：
- 将 AutoGenerateColumns 设置为 False
- 将列定义添加到 C1FlexGridBase.Cols() 集合。
- 将 DataTable 绑定到 flexgrid

例如，

Private _dt As System.Data.DataTable

Private Sub LoadFlexGrid()

    'create new table
    _dt = New System.Data.DataTable("MyDataTable")
    _dt.Columns.Add("CustomerId", GetType(Integer))
    _dt.Columns.Add("CustomerName", GetType(String))

    'populate it
    _dt.Rows.Add(New Object() {12, "Joe"})
    _dt.Rows.Add(New Object() {14, "Bob"})

    'define column grid columns
    Dim col1 As C1.Win.C1FlexGrid.Column
    col1 = flex.Cols.Add()
    col1.Name = "CustomerId"
    col1.Caption = "Customer Id"

    Dim col2 As C1.Win.C1FlexGrid.Column
    col2 = flex.Cols.Add()
    col2.Name = "CustomerName"
    col2.Caption = "Name"

    'bind the grid to it
    flex.AutoGenerateColumns = False
    flex.DataSource = _dt

End Sub
