如何在wpf中获取datagrid特定的单元格值？ [英] how to get datagrid particular cell value in wpf ?

问题描述

嗨朋友们，



在我的项目中，我放了一个 DataGrid 来查看数据库数据。现在我想要在DataGrid中选择的单元格值。



我的代码

Hi Friends,

In my project I put one DataGrid for viewing database data. Now I want the cell value which I selected in the DataGrid.

for that I code

 private void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
 textBox1.Text = dataGrid1.SelectedItem.ToString();// TextSelection;
               
}

我只想要代码名称。 ：-\即'cs11'。但我得到了

I want the code name only. :-\ that is 'cs11'. but I got

{ name = tuutusdydfh, code = cs11 }

。，



所以我也试试这些代码。

.,

so I try these code also.

// textBox1.Text = dataGrid1.SelectedCells[1].ToString();
  //textBox1.Text = dataGrid1.CurrentCell.Item.ToString();
  // textBox1.Text = dataGrid1.ItemsSource.ToString();
  //textBox1.Text = dataGrid1.Items.ToString();

但是我不能得到。我只想要代码名称，帮帮我朋友。



我的数据网格（xaml）： -

but I cant get. I want the code name only, help me friends.

My Data Grid (xaml):-

<datagrid name="dataGrid1" itemssource="{Binding }" borderbrush="Gray" borderthickness="5" margin="45,91,30,116">
                 Background="LightGray"
                 RowBackground="SeaShell"
                 RowHeight="30"
                 ColumnWidth="150"
                 AlternatingRowremoved="Lavender"
                 HorizontalScrollBarVisibility="Visible"
                 VerticalScrollBarVisibility="Visible"
                 MouseDoubleClick="dataGrid1_MouseDoubleClick"
                 SelectionChanged="dataGrid1_SelectionChanged" /></datagrid>

代码： -

Code :-

if (paramType == "Hall")
           {
               //var dbList = from recs in MainWindow.mcsEntity.mcs_hall orderby recs.mcs_Hall_Name
                    //        select recs;
               //dataGrid1.DataContext = dbList;
               dataGrid1.DataContext = from re in MainWindow.mcsEntity.mcs_hall
                                       orderby re.mcs_Hall_Code
                                       select new
                                       {
                                           name = re.mcs_Hall_Name,
                                           code = re.mcs_Hall_Code
                                       };


           }

推荐答案

你可以使用一个班级

Hi,

you can use a class

public class MyClass
{
    public string Name {get;set;}
    public int Code { get; set; }
}

并在Linqstatement中创建no var。您可以在班级中创建新对象：

and create in the Linqstatement no var. You create new objects from your class:

dataGrid1.DataContext = from re in MainWindow.mcsEntity.mcs_hall
                                       orderby re.mcs_Hall_Code
                                       select new MyClass
                                       {
                                           Name = re.mcs_Hall_Name,
                                           Code = re.mcs_Hall_Code
                                       };

你的SelectionChanged事件中的
你将selectedItem转换为你的类：

in your SelectionChanged event you convert the selectedItem to your class:

private void DataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (e.AddedItems.Count > 0)
            {
               textBox1.Text = (e.AddedItems[0] as MyClass).Name;
            }
        }

希望有帮助

Hope that helps

我认为此 [ ^ MSDN上的线程有您正在寻找的解决方案。

I think that this[^] thread on MSDN has the solution you are looking for.

for (int j = 0; j < dataGrid1.Columns.Count; j++)
            {
                for (int i = 0; i < dataGrid1.Items.Count - 1; i++)
                {
                    string s=(dataGrid1.Items[i] as DataRowView).Row.ItemArray[j].ToString();
                }
}
