数值,其中一个具有progressbar值。如何使“Progress1”隐藏或删除,但仍保留“Progress2”中的值

这是主要的xaml

        <DataGrid.Columns>

            <!--#region Program Number -->
            <DataGridTemplateColumn SortMemberPath="#" Header="#">

Here is what it look like (第一次发布问题,如果有什么遗漏,我很乐意补充)

问题是列正在自动生成,因为您没有设置 AutoGeneratedColumns="false" 和 true

false 这个 DataGrid

有关更多信息,请参阅 DataGrid.AutoGenerateColumns Property

如果将其设置为false,则只会看到进度条。所以你必须指定其他列,就像你用 ProgressBar

你可以这样做

<DataGrid.Columns> 
    <DataGridTextColumn Binding="{Binding ProgramID}"/>
    <DataGridTextColumn Binding="{Binding Name}"/>
    <DataGridTextColumn Binding="{Binding Size}"/>
    <DataGridTemplateColumn SortMemberPath="Progress" Header="Progress2">                                            
       <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <ProgressBar Value="{Binding Progress1}"/>
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
</DataGrid.Columns>

编辑

DataGridTextColumn

<DataGridTextColumn SortMemberPath="ProgramID" 
                    Header="#" 
                    Binding="{Binding ProgramID}"/>

TemplateColumn 当您想要显示文本时。更容易;)

CellEditingTemplate CellTemplate .

这个单元格处于编辑模式时将显示的模板。

这个当单元格未处于编辑模式时将显示。

当你不想按自己的方式做时,你必须像这样改变

<DataGridTemplateColumn SortMemberPath="ProgramID" Header="#">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding ProgramID}"/>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
