c - 在 DevExpress vb.net 中使用 CheckBoxList 分配和评估？

Question

您好，我的代码示例是:

/* bdEmpresa(绑定(bind)源) 包含:

从 Empresa 中选择 idEmpresa、Nombre、Acceso

结果

1、Empresa1、true

2、Empresa2、假

3、Empresa2、true

*/

clEmpresas.DataSource = bdEmpresa

clEmpresas.DisplayMember = ? (名称)

clEmpresas.ValueMember = ? (附件)

Answer 1

这是我们将使用的代码

        With clEmpresas.Properties
            If .DataSource IsNot Nothing Then .DataSource = Nothing
            .DataSource =  bdEmpresa 
            If .DataSource.rows.count = 0 Then Return Nothing 'no data to load
            'get the names from the dataset, don't expect them to be specific names
            .ValueMember = .DataSource.rows(0).Table.Columns(0).ColumnName
            .DisplayMember = .DataSource.rows(0).Table.Columns(1).ColumnName

            'Set the selected items, comma separated list of ids
            If selectedIds <> "" Then
                For i As Integer = 0 To .ItemCount - 1
                    If Array.IndexOf(selectedIds.Split(","), .GetItemValue(i).ToString) >= 0 Then
                        .SetItemChecked(i, True)
                    End If
                Next
            End If

        End With
