WPF DataGrid的行标题可见性错误错误、标题、见性、WPF

2023-09-04 02:42:02 作者：醉迴三笙夣

我使用一个DataGrid来显示几个领域，其中之一是多行描述。网格显示数据就好了，直到我试图通过设置 HeadersVisibility =列来隐藏标题行。表头行消失，但后来当我滚动的行头重新出现了一些随机的行。

我已经把范围缩小到显示多行描述的列。只要我离开这个专栏了，那我就没有这个问题。我试图分开双方\ r \ N和\ N的线，但没有工作。是否在DataGrid支持多行文本字段？

下面是一个图片显示正在发生的事情和XAML我用来创建网格。

＆LT; DataGrid中的DataContext ={的StaticResource personRepository}
          的ItemsSource ={结合PersonList，模式=单向}
          的AutoGenerateColumns =FALSE
          HeadersVisibility =栏
          CanUserSortColumns =假
          的SelectionMode =扩展
          的IsReadOnly =真＆GT;

    ＆LT; DataGrid.Columns＆GT;
        ＆LT; DataGridTextColumn标题=IDWIDTH =80绑定={结合编号，模式=单向}/＆GT;
        ＆LT; DataGridTextColumn标题=名WIDTH =150绑定={结合名字，模式=单向}/＆GT;
        ＆LT; DataGridTextColumn标题=姓WIDTH =150绑定={结合姓氏，模式=单向}/＆GT;
        ＆LT; DataGridTextColumn标题=说明WIDTH =*绑定={绑定描述，模式=单向}/＆GT;
    ＆LT; /DataGrid.Columns>
＆LT; /数据网格＆GT;

解决方案

尝试设置 RowHeaderWidth = 0 而不是 HeaderVisibility

I am using a DataGrid to display several fields, one of which is a multi-line description. The grid displays the data just fine until I try to hide the header rows by setting HeadersVisibility="Column". The header rows disappear but then while I am scrolling the row header reappears for some random rows.

I have narrowed it down to the column that displays multi-line description. As long as I leave this column off, then I don't have this issue. I have tried separating the lines by both "\r\n" and "\n" but neither work. Does the DataGrid support multi-line text fields?

Below is a picture to show what is happening and the XAML I used to create the grid.

<DataGrid DataContext="{StaticResource personRepository}"
          ItemsSource="{Binding PersonList, Mode=OneWay}"
          AutoGenerateColumns="False"
          HeadersVisibility="Column"
          CanUserSortColumns="False"
          SelectionMode="Extended"
          IsReadOnly="True">

    <DataGrid.Columns>
        <DataGridTextColumn Header="Id" Width="80" Binding="{Binding Id, Mode=OneWay}" />
        <DataGridTextColumn Header="First Name" Width="150" Binding="{Binding FirstName, Mode=OneWay}" />
        <DataGridTextColumn Header="Last Name" Width="150" Binding="{Binding LastName, Mode=OneWay}" />
        <DataGridTextColumn Header="Description" Width="*" Binding="{Binding Description, Mode=OneWay}" />
    </DataGrid.Columns>
</DataGrid>

解决方案

Try setting RowHeaderWidth = 0 instead of HeaderVisibility
