无法编辑我的DataGrid WPF Framework 4.5的单元格 [英] Cannot edit cells of my DataGrid WPF Framework 4.5

问题描述

我的ObservableCollection有三个项目，这些行一直显示在datagrid中。
我不能将DataGrid的单个单元格变成编辑模式。我尝试点击，点击，双击，F2，...，但整行保持选择。我如何让用户编辑datagrid。
我在其他帖子中发现了类似的datagrid编辑问题，但没有人解决我的问题。这是代码（WPF NetFramework 4.5）。通常，只有第一列是不可编辑的（只读）。

My ObservableCollection has three items, and the rows are consistently shown in the datagrid. I cannot turn into edit mode a single cell of my DataGrid. I tried click, click-click, double-click, F2,…, but the whole row stay selected. How can I let the user edit the datagrid. I found similar datagrid edit-questions in other posts but no-one solved my problem. Here is the code (WPF NetFramework 4.5). Pursposely, only the first column is non-editable (readonly).

<DataGrid Name="myDataGrid" Grid.Row="2" AutoGenerateColumns="False" ItemsSource="{Binding}" IsReadOnly="False">
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="name" IsReadOnly="True" Width="200"  >
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTemplateColumn Header="Formulation" Width="100" IsReadOnly="False">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding FormulationStr}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding FormulationStr}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
        <DataGridTemplateColumn Header="volume Diff" Width="100" IsReadOnly="False">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding volumeDiff}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding volumeDiff}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

推荐答案

您已将 TextBlock 在单元格模板以及单元格编辑模板中。这就是为什么你没有注意到按F2和双击单元格的任何变化，因为无论它永远是 TextBlock ，你不能编辑。

You have placed TextBlock in cell template as well as in cell editing template. That's why you are not noticing any change on pressing F2 and double-clicking the cell since no matter what it will always be TextBlock which you can't edit.

在 CellEditingTemplate 中放置 TextBox ，就像这样 -

Either placed TextBox in your CellEditingTemplate like this -

<DataGridTemplateColumn Header="Formulation" Width="100" IsReadOnly="False">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding FormulationStr}" />
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
    <DataGridTemplateColumn.CellEditingTemplate>
        <DataTemplate>
            <TextBox Text="{Binding FormulationStr}" />
        </DataTemplate>
    </DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>

或者只需使用 DataGridTextColumn 的 DataGridTemplateColumn ，其内部提供支持，您想通过上述代码来实现 -

Or either simply use the DataGridTextColumn in place of DataGridTemplateColumn which internally provides the support what are you trying to achive by the above code -

<DataGridTextColumn Header="Formulation" Width="100" IsReadOnly="False" Binding="{Binding FormulationStr}" />
