请教各位高手一个WPF用户控件的问题

r4 2014-03-06 10:39:42
我在VS2010下写了一个用户控件，内容主要是8个TextBox，并且将这个控件作为DataGrid的Cell,现在的问题是我使用
List<ganttLine> _data = new List<ganttLine>();
_data.Add(new ganttLine());
_data.Add(new ganttLine());
_dataX[0].percentage0 = 0.2f;
_dataX[0].percentage1 = 0.25f;
_dataX[0].percentage2 = 0.02f;
_dataX[0].percentage3 = 0.175f;
datagrid.Items.Add(_data);
的方式加入新的数据后，这些加入的值全部都是初始值，对他们的修改都是无效的，percentage0 ~percentage3 4个属性本来是用来设置其中4个TextBox的内容的，但是现在一点作用也没有，
这样的情况只出现在将这个控件作为DataGrid的Item的时候，如果我将控件直接放在窗口上就没问题，请问这是为什么啊？下面是XAML
<DataGrid x:Name="dgTimeline" AutoGenerateColumns="False" HorizontalAlignment="Stretch" CanUserAddRows="False" CanUserResizeColumns="False" IsReadOnly="True" VerticalAlignment="Stretch" SelectionUnit="Cell" Grid.Row="1">
<DataGrid.Columns>
<DataGridTemplateColumn Width="Auto">
<DataGridTemplateColumn.HeaderTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="186"/>
</Grid.ColumnDefinitions>
<Grid HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="24" />
<RowDefinition Height="1" />
<RowDefinition Height="24" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="48*"/>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="48*"/>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="48*"/>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="48*"/>
</Grid.ColumnDefinitions>
<ContentPresenter Content="年" x:Name="Year" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.ColumnSpan="7" />
<Rectangle Fill="#FFC9CACA" VerticalAlignment="Stretch" Height="1" Grid.Row="1" Grid.ColumnSpan="7" />
<ContentPresenter Content="1季度" Grid.Row="2" VerticalAlignment="Center" HorizontalAlignment="Center" />
<Rectangle Fill="#FFC9CACA" VerticalAlignment="Stretch" Width="1" Visibility="Visible" Grid.Row="2" Grid.Column="1" />
<ContentPresenter Content="2季度" Grid.Row="2" Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Center" />
<Rectangle Fill="#FFC9CACA" VerticalAlignment="Stretch" Width="1" Visibility="Visible" Grid.Row="2" Grid.Column="3" />
<ContentPresenter Content="3季度" Grid.Row="2" Grid.Column="4" VerticalAlignment="Center" HorizontalAlignment="Center" />
<Rectangle Fill="#FFC9CACA" VerticalAlignment="Stretch" Width="1" Visibility="Visible" Grid.Row="2" Grid.Column="5" />
<ContentPresenter Content="4季度" Grid.Row="2" Grid.Column="6" VerticalAlignment="Center" HorizontalAlignment="Center" />
</Grid>
</Grid>
</DataTemplate>
</DataGridTemplateColumn.HeaderTemplate>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<local:ganttLine/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
另外还有一个问题就是我生成了一个复合表头，现在想在代码里动态修改表头的文字，应该怎么做的，我尝试获得表头的对象，但是没有成功。

非常感谢，进度条我自己再试试看吧，另外请问，我想在代码里手工设置<ContentPresenter Content="年" x:Name="Year" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.ColumnSpan="7" /> 的Content的内容，就是那个“年”字，应该怎么做呢？
        private T FindVisualChildByName<T>(DependencyObject parent, string name) where T : DependencyObject
        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++) {
                var child = VisualTreeHelper.GetChild(parent, i);
                string controlName = child.GetValue(Control.NameProperty) as string;
                if (controlName == name) {
                    return child as T;
                } else {
                    T result = FindVisualChildByName<T>(child, name);
                    if (result != null)
                        return result;
                }
            }
            return null;
        }
调用： 
            ContentPresenter temp = FindVisualChildByName<ContentPresenter>(this.dgTimeline, "Year");
            if (temp != null) {
                temp.Content = "自定义";
            }

您能给我一个在DataGrid中使用用户控件的例子吗？我主要就是在这个问题上没搞清楚
很少有用用户控件当模板的例子，不过话说回来，确实可以直接不用用户控件，自定义那一列的内容就可以，明早起来做个小例子吧。

那个进度条一样的东西一共有3*4=12个，根据传进来的Months列表和Year进行比较，如果Year+对应的块所表示的年/月在Months所表示的时间段内，这个对应的块就会被显示

楼主的ganttLine是那个用户控件？如果是，看来你连DataGrid中添加数据的方法也错了。如果方便的话，建议你简化一下，提供一个Demo让别人来修改会更好。

就是一个复合表头，但是datagrid的表头个数是动态的，表格中的元素是一个用户控件，内容是4组TextBox,每组由两个TextBox组成，其中一个现实百分比数字，另外一个显示总数*百分比之后的结果

要不你说说，已知Months、Year、sum、percentage0~percentage3（因为我看你初始化是会初始化这几个属性）的值，界面对应的效果应该是怎么样，现在我只看懂CTD？和CTU？跟什么属性有关，而有些像进度条的效果我不太确定，还有那个sum是怎么计算也不是很懂（我自己对依赖属性也不是很会，所以如果我改的话，或许不使用依赖属性）。

用了依赖是因为那个sum属性希望能和另外一个dataGrid有绑定，我是第一次用wpf，C#也只是第二次用而已，很多东西都不了解，胡乱抄了一些而已。 请问我应该怎么做呢。 现在的想法是因为这个DataGrid的数据行和列都不是固定数目的，直接用Table绑定不好做，所以想按老习惯写，不用绑定，直接把需要的数据Add进去，但是一直没成功。

看了下，有几个问题，不知为何设计了依赖属性，但界面中貌似没有用到；在DataGrid中应该是有一些绑定语句的；dgTimeline.Items.Add(new DataX() { A_ = new ganttLine(), B_ = new ganttLine() }); 这里是想向DataGrid中添加一个用户控件？！如果是，那楼主是完全搞错用法了吧。 这里DataGrid显示不出数据的原因也是如此，而且我发觉楼主定义属性貌似跟我平时看的代码不一样，楼主的属性获取需要访问界面控件，感觉这样设计不太好。如果楼主一定要以上述基础来改，我还真不知道怎么改好。
