我是wpf的新手,尝试将静态定义的DataGrid的Items.Count属性绑定到我的自定义控件的标签上。
我目前的实现如下所示。但是标签仍然是空的:I
定义DataGrid的类:
public class BindingNavigator : Control
{
private static DataGrid dataGrid;
static BindingNavigator()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(BindingNavigator), new FrameworkPro
public class EventLogView : UserControl
{
private DataGrid dataGrid;
public EventLogView()
{
this.InitializeComponent();
dataGrid = this.FindControl<DataGrid>("EventLogsDataGrid");
this.dataGrid.LoadingRow += new EventHandler<DataGridRowEventArgs&
又是我。^_^我可以问一下如何按类别过滤特定的记录吗?我只知道如何过滤一个类别。这是我的代码。请帮帮我。谢谢!
If txtName.Text = "" Then
MsgBox "Please enter what you want to filter.", vbInformation, "Message Box"
txtName.SetFocus
Else
If Not myRS.EditMode And myRS.BOF = True Then
MsgBox "No record found!", vbCritical, &
我有一个数据网格,其中我使用DragAndDropBehavior向上/向下移动项目:
public class DataGridRowDragAndDropBehavior
{
public delegate Point GetPosition(IInputElement element);
int rowIndex = -1;
public static DependencyProperty DataGridDragAndDropEnabled =
DependencyProperty.R
