如何在不使用mvvm的情况下在Silverlight中实现货币管理？ [英] How to implement currency management in Silverlight without using mvvm?

问题描述

我需要具有与Windows窗体中使用的BindingSource类似的功能。假设我们有一个数据网格和文本框都绑定到相同的数据表。在选择更改数据网格时，我想要更改文本框值。

这是在windows窗体中工作..我需要在银灯中实现相同的功能。

 <代码样式="边距：0px;填充：0px;边框：0px;字体大小：13px;字体系列：Consolas，Menlo，Monaco，'Lucida控制台'，'解放单声道'，'DejaVu Sans Mono'，'Bitstream Vera Sans Mono'，'Courier New'，monospace，sans-serif; white-space ：inherit"> <网格   样式  =  "   {  StaticResource GridStyle  }  "     Horizo​​ntalAlignment   =  " Stretch"    >   
  < Grid.RowDefinitions>   
  < RowDefinition    高度  =  " *"     />   
 
  < /Grid.RowDefinitions>   
 
  <网格   网格 。 行  =  " 0"  >   
  < Grid.RowDefinitions>   
  < RowDefinition    高度  =  " *"     />   
  < RowDefinition    高度  =  " *"     />   
  < /Grid.RowDefinitions>   
 
 
  < c1grid：C1DataGrid     x：FieldModifier   =  "公共"     Horizo​​ntalScrollBarVisibility   =  " Auto"    网格 。 行  =  " 1"     x：名称  =  " gridTest"    样式  =  "   {  StaticResource DataGridStyle  }  "   
   MouseRightButtonUp   =  " gridTest_MouseRightButtonUp"   
   MouseRightButtonDown   =  " gridTest_MouseRightButtonDown"    >   
 
  < c1grid：C1DataGrid.Columns>   
 
  < c1grid：DataGridTextColumn    标题  =  " {Binding Strings.strhdrSubcaseID，Source = {StaticResource localization}}"    绑定  =  " {Binding Path = SUBINCIDENT__ID_NUMBER}"     FilterMemberPath   =  " SUBINCIDENT__ID_NUMBER"     SortMemberPath   =  " SUBINCIDENT__ID_NUMBER"   />   
  < c1grid：DataGridTextColumn    标题  =  " {Binding Strings.strhdrWOStage，Source = {StaticResource localization}}"    绑定  =  " {Binding Path = WORK_ORDER__STATUS}"     FilterMemberPath   =  " WORK_ORDER__STATUS"     SortMemberPath   =  " WORK_ORDER__STATUS"   />   
  < c1grid：DataGridTextColumn    标题  =  " {Binding Strings.strhdrSLACondition，Source = {StaticResource localization}}"    绑定  =  " {Binding Path = WORK_ORDER__CONDITION}"     FilterMemberPath   =  " WORK_ORDER__CONDITION&qu​​ot;     SortMemberPath   =  " WORK_ORDER__CONDITION&qu​​ot;   />   
  < c1grid：DataGridTextColumn    标题  =  "状态"    绑定  =  " {Binding Path = STATUS}"     FilterMemberPath   =  " STATUS"     SortMemberPath   =  " STATUS"    可见性  =  " Collapsed"   />   
  < / c1grid：C1DataGrid.Columns>   
  < / c1grid：C1DataGrid>   
  < TextBox     x：名称  =  " txt_IDNumber"    文字  =  " {Binding Path = SUBINCIDENT__ID_NUMBER}"    网格 。 行  =  " 0"    网格 。 列  =  " 4"     TextWrapping   =  " Wrap"    保证金  =  " 4,0,0,4"     VerticalAlignment   =  " Stretch"   
  高度  =  " 22"     FontSize   =  " 11"    样式  =  "   {  StaticResource TextboxStyle  }  "     />   
 
 
  < / Grid>   
  < / Grid>   

我没有使用MVVM或MVP模式。

嗨asritha.reddy，

据我所知，我们无法绑定列表在Silverlight应用程序的TextBox中。

根据您的描述，当在DataGrid控件中选择相关项时，您希望在TextBox中显示SUBINCIDENT__ID_NUMBER属性，是不是？

我们只需要为DataGrid添加一个SelectionChanged事件，然后在此事件中更改Text属性以显示SUBINCIDENT__ID_NUMBER。以下示例代码实现您的要求。希望可以帮助您。

< sdk：DataGrid Horizo​​ntalScrollBarVisibility =" Auto" Grid.Row =" 1" x：Name =" gridTest"  SelectionChanged =" gridTest_SelectionChanged" > ;< / sdk：DataGrid> 
< TextBox x：Name =" txt_IDNumber" T EXT ="" Grid.Row = QUOT; 0" Grid.Column = QUOT; 4英寸TextWrapping = QUOT;包覆与QUOT;余量= QUOT; 4,0,0,4" VerticalAlignment = QUOT;拉伸" 
 Height =" 22"字号= QUOT 11 QUOT; /> 

 private void gridTest_SelectionChanged（object sender，SelectionChangedEventArgs e）
 {
 TestData selected =（TestData）gridTest.SelectedItem; 
 
 txt_IDNumber.Text = selected.SUBINCIDENT__ID_NUMBER; 
 
} 

最好的问候，

I need to have similar functionality as BindingSource we use in windows forms. Suppose we have a data grid and text box both are bind with same data table. On the selection change of the data grid i would like to text box value to be changed.

This is working in windows forms.. I need to implement same functionality in silver light.

<Grid Style="{StaticResource GridStyle}" HorizontalAlignment="Stretch" >
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />

            </Grid.RowDefinitions>

            <Grid Grid.Row="0">
                <Grid.RowDefinitions>
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                </Grid.RowDefinitions>


                <c1grid:C1DataGrid x:FieldModifier="Public" HorizontalScrollBarVisibility="Auto" Grid.Row="1" x:Name="gridTest" Style="{StaticResource DataGridStyle}" 
                                MouseRightButtonUp="gridTest_MouseRightButtonUp" 
                                   MouseRightButtonDown="gridTest_MouseRightButtonDown" >

                    <c1grid:C1DataGrid.Columns>

                        <c1grid:DataGridTextColumn Header="{Binding Strings.strhdrSubcaseID, Source={StaticResource localization}}"  Binding="{Binding Path=SUBINCIDENT__ID_NUMBER}" FilterMemberPath="SUBINCIDENT__ID_NUMBER" SortMemberPath="SUBINCIDENT__ID_NUMBER"/>
                        <c1grid:DataGridTextColumn Header="{Binding Strings.strhdrWOStage, Source={StaticResource localization}}"  Binding="{Binding Path=WORK_ORDER__STATUS}" FilterMemberPath="WORK_ORDER__STATUS" SortMemberPath="WORK_ORDER__STATUS"/>
                        <c1grid:DataGridTextColumn Header="{Binding Strings.strhdrSLACondition, Source={StaticResource localization}}"  Binding="{Binding Path=WORK_ORDER__CONDITION}" FilterMemberPath="WORK_ORDER__CONDITION" SortMemberPath="WORK_ORDER__CONDITION"/>
                        <c1grid:DataGridTextColumn Header="Status" Binding="{Binding Path=STATUS}" FilterMemberPath="STATUS"  SortMemberPath="STATUS" Visibility="Collapsed"/>
                    </c1grid:C1DataGrid.Columns>
                </c1grid:C1DataGrid>
<TextBox  x:Name="txt_IDNumber"  Text="{Binding Path=SUBINCIDENT__ID_NUMBER}"  Grid.Row="0" Grid.Column="4" TextWrapping="Wrap"  Margin="4,0,0,4" VerticalAlignment="Stretch"
                            Height="22" FontSize="11" Style="{StaticResource TextboxStyle}" />


            </Grid>
     </Grid>

I'm not using MVVM OR MVP pattern.

Hi asritha.reddy,

As far as I know, we could not bind a list in TextBox in Silverlight application.

According to your description, you want to show the SUBINCIDENT__ID_NUMBER property in TextBox when the related Item is selected in DataGrid control, is it right?

We just need to add a SelectionChanged event for DataGrid and then change the Text property in this event to show the SUBINCIDENT__ID_NUMBER. Following sample code implement your requirement。 Hope that can help you.

<sdk:DataGrid  HorizontalScrollBarVisibility="Auto" Grid.Row="1" x:Name="gridTest" SelectionChanged="gridTest_SelectionChanged"></sdk:DataGrid>
<TextBox  x:Name="txt_IDNumber"  Text=""  Grid.Row="0" Grid.Column="4" TextWrapping="Wrap"  Margin="4,0,0,4" VerticalAlignment="Stretch"
                            Height="22" FontSize="11" />

 private void gridTest_SelectionChanged(object sender, SelectionChangedEventArgs e)
 {
      TestData selected = (TestData)gridTest.SelectedItem;

      txt_IDNumber.Text = selected.SUBINCIDENT__ID_NUMBER;

 }
