WPF：如何将'System.Collections.Generic.Dictionary< string，object>'转换为'System.Windows.Controls.DataGridRow' [英] WPF: How to convert 'System.Collections.Generic.Dictionary<string,object>' to 'System.Windows.Controls.DataGridRow'

问题描述

我有一个datagrid，我将使用" ObservableCollection< Dictionary< string，object>>绑定行。 dataRows {get;组; }"

I have a datagrid, i will be binding rows using "ObservableCollection<Dictionary<string, object>> dataRows { get; set; }"

datagrid.itemssource = datarows;

datagrid.itemssource = datarows;

当我尝试访问一个项目时，我收到它作为带有Dictionary的可观察集合。当我将项目传递给下面的步骤时，我接收行为空。

When I try to access an item I am receiving it as observable collection with Dictionary. When I pass the item to the below step I am receiving row as null.

foreach（myDataGrid.Items中的var项目）

foreach(var item in myDataGrid.Items)

{

DataGridRow row =（DataGridRow）scni.DataGridInstance.DataGridControl.ItemContainerGenerator.ContainerFromItem（item）;

DataGridRow row = (DataGridRow)scni.DataGridInstance.DataGridControl.ItemContainerGenerator.ContainerFromItem(item);

}

我认为我们传递该项目的方式不正确。我不知道，我怎么能通过正确的项目来准确地从他们的单元格中获取行。 

I thought the way we are passing the item is not in proper format. I don't know, how can I pass proper item to get row exactly and from their cell. 

因此，我试图转换"字典"到" Datagridrow "我需要访问Cell值及其属性。

Hence, I am trying to convert "dictionary" to "Datagridrow" where I need to access Cell value and its properties.

我的最终目标是从datagrid获取每个单元格值并更改单元格属性（如前景/背景/文本对齐等）基于单元格值。

My final aim is to get each and every cell value from the datagrid and change cell properties (like foreground/Background/Text Allignment etc) based on the cell value.

注意：我无法从XAML端执行此操作。我需要通过改变c＃代码来做一切事情。

Note: I cannot do it from the XAML side. I need to do everything programitically by doing changes in c# code

请帮我解决这个问题。

提前致谢

嗨aviapt，

Hi aviapt,

根据你的描述，你想使用字典bing datagrid，是或否？如果是，你可以像observablecollection那样做。

According to your description, you want to bing datagrid using dictionary, yes or not? If yes, you can do this like observablecollection.

 <StackPanel>
        <DataGrid
           AutoGenerateColumns="False" 
            Width="300"
            Height="300"
            ItemsSource="{Binding}">
            <DataGrid.Columns>
                <DataGridTextColumn
                    Width="50"
                    Binding="{Binding Key}"
                    Header="Key" />
                <DataGridTextColumn
                    Width="50"
                    Binding="{Binding Value}"
                    Header="Value" />
            </DataGrid.Columns>
        </DataGrid>
    </StackPanel>

 Dictionary<int, string> dic;
        public Window4()
        {
            InitializeComponent();
            dic = new Dictionary<int, string>();
          
            dic.Add(1, "Cherry");
            dic.Add(2, "Barry");
            dic.Add(3, "Mattew");
            this.DataContext = dic;                           
        }

您可以按单元格值更改单元格属性。

The you can change cell property by cell value.

最好的问候，

Cherry
