Question

Due the nature of our software, we have to create our datagrid columns dynamically in code behind and add it then to the datagrid like this:

DataGridBoundColumn dataGridBoundColumn = new DataGridTextColumn
                                                          {
                                                              CellStyle = ...,                                                                            
                                                              Header = header,
                                                              Binding = binding
                                                          };
reportDataGrid.Columns.Add(dataGridBoundColumn);

我们现在需要一栏标题上的工具:

ToolTipService.SetToolTip(dataGridBoundColumn, "ENTER VALUE");

这样做也会奏效。然而,我需要将工具的价值与观念Model上的财产挂钩。我知道如何在Xaml中这样做,但不知道如何在法典中这样做。

希望得到任何帮助,

UPDATE:

由于Steve的回答,我能够稍作改动:

Binding bindingBoundToTooltipProperty = new Binding()
                                   {
                                       Source = reportDataGrid.DataContext, 
                                       Path = new PropertyPath("ToolTipSorting")
                                   };


BindingOperations.SetBinding(dataGridBoundColumn, ToolTipService.ToolTipProperty, bindingBoundToTooltipProperty);

如果数据GridColumn HeaderStyle是定制的,确保把这些内容添加到模板中:

<Trigger Property="IsMouseOver" Value="True">
    <Setter Property="ToolTip" Value="{Binding Column.(ToolTipService.ToolTip), RelativeSource={RelativeSource Self}}"/>
</Trigger>

你们应当能够建立如下具有约束力的机制:

BindingOperations.SetBinding(dataGridBoundColumn,
    ToolTipService.ToolTipProperty,
    new Binding("Path.To.My.Property"));

注:<代码>DataContext of this will be the Value of the Header property on the栏

You want to bind to a property on the view model; assuming that your view model is the DataContext for the DataGrid you would want to change the binding to something like:

new Binding("DataContext.ToolTipSorting")
{
    RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor)
    {
        AncestorType = typeof(DataGrid)
    }
}

试图确定第一组母物的类型:<代码>DataGrid,并抄录其<代码>的价值。
