Question

我有select语句，显示datagrid中的所选项目。

cmdSel.CommandText = "select id,Name,TypeID,StatusID from document where Contains([Context],'FormsOf (INFLECTIONAL, \"" + TextBoxSearch.Text + "\")')";

<WpfToolkit:DataGrid IsTextSearchEnabled="True" IsReadOnly="True" CanUserSortColumns="True" AutoGenerateColumns="False" Name="DataGrid1" 
                     ItemsSource="{Binding Path=MainSearchBinding}" SelectionChanged="DataGrid1_SelectionChanged">              
    <WpfToolkit:DataGrid.Columns>
        <WpfToolkit:DataGridTextColumn Header="Номер" Width="63" Binding="{Binding id}" IsReadOnly="false" />
        <WpfToolkit:DataGridTextColumn Header="Название" Width="*" Binding="{Binding Name}" IsReadOnly="false" />
    </WpfToolkit:DataGrid.Columns>

我有另一个用richtextbox的用户控件。我想通过点击datagrid中的数据来显示richtextbox上的特定数据。

我尝试了我在这里找到的东西，它没有帮助我。请指点我。提前谢谢。

他是我的问题的答案，有人可能需要。首先点击鼠标我正在寻找id然后根据该ID选择Context，这里是代码

 private void OnMouseClick(object sender, MouseButtonEventArgs e)
        {


            IList rows = DataGrid1.SelectedItems;
            DataRowView row = (DataRowView)DataGrid1.SelectedItems[0];
            int a = (int)row["ID"];//It is returning the id of selected row

            DocumentView docview = new DocumentView();

            commProc = new SqlCommand("SELECT Context from Document where ID='" + a + "'", MainWindow.conn);//Depending on ID I am selecting context.
            SqlDataReader dr = commProc.ExecuteReader();
            string str;
            FlowDocument document = new FlowDocument();
            Paragraph paragraph = new Paragraph();

            if (dr.Read())
            {
                str = (string)dr["Context"];
                paragraph.Inlines.Add(new Bold(new Run(str)));
                document.Blocks.Add(paragraph);
                docview.RBox.Document = document;

            }

            dr.Close();



            var tabControl = (sender as DataGrid).FindParent<TabControl>();


            tabControl.Items.Add(new TabItem() { Header = "Документ", Content = docview, IsSelected = true });

        }
