WPF Datagrid与Xml绑定 [英] WPF Datagrid Bind with Xml

问题描述

大家好，

我必须将一个xml绑定到WPF中的datagrid。



示例输入Xml

 <  项目 >  
 <  项目   标记  =  Tag1    value   =  Value1  /  >  
 < span class =code-keyword><  项目    tag   =  Tag2    value   =  Value2  /  >  
 <  项目   标记  =  Tag3    value   =  Value3  /  < span class =code-keyword>>  
 <   Items /  >  

我必须在设计时将xml绑定到datagrid时间使得xpath条件应该是这样的。

 <   DataGrid    名称  =   dgNoMethod    ItemsSource  < span class =code-keyword> =  {Binding}    AutoGenerateColumns   =  False   宽度  = 自动   高度  = 自动 >  
 <   DataGrid.Columns  >  
 <   DataGridTextColumn    标题  = 扩展单位 < span class =code-attribute>   Binding   =  {Binding XPath = Attribute [value] .Value}      /  >  
 <  < span class =code-leadattribute> DataGridTextColumn    标题  =  Header1   绑定  =  {Binding XPath = Attribute [value] .Value}    /  >  
 <   DataGridTextColumn    标题  =  Header2    Binding   =  {Binding XPath = Attribute [value] .Value}    /  >  
 <   DataGridTextColumn    标题  =  Header3    Binding   =  {Binding XPath = Attribute [value] .Value}    /  >  
 <   / DataGrid.Columns  >  
 <   / DataGrid  >  

场景：



我想为网格的每一列写一个Xpath查询，这样如果值Header1 Column的标签是'Tag1'然后要绑定到该列的值应该是Value1



所以我想要一个像这样的XPath查询。

< datagridtextcolumn header =Extending Unitbinding ={Bi nding XPath = Items / Item [@ tag ='Tag1']}>

如果Xpath查询具有'Tag1'，那么要绑定到Binding属性的值应为Value1 br />


与其他栏类似

要绑定的值Value2和XPath查询应该有tag ='Tag2'

要绑定的值Value3和XPath查询应该有tag ='Tag3'





希望这样可以清除场景。

解决方案

您可以从这篇简短的文章开始，其中演示了XPath的使用： http ：//www.c-sharpcorner.com/UploadFile/mamta_m/binding-xml-to-a-wpf-datagrid [ ^ ]。

Hi All,
I have to bind a xml to datagrid in WPF.

Sample Input Xml

<Items>
  <Item tag="Tag1" value="Value1"/>
  <Item tag="Tag2" value="Value2"/>
  <Item tag="Tag3" value="Value3"/>
<Items/>

I have to bind the xml to datagrid at design time such that the xpath condition should be like this.

<DataGrid Name="dgNoMethod" ItemsSource="{Binding}" AutoGenerateColumns="False" Width="Auto" Height="Auto">
<DataGrid.Columns>
 <DataGridTextColumn Header="Extending Unit" Binding="{Binding XPath=Attribute[value].Value}"  />
                <DataGridTextColumn Header="Header1" Binding="{Binding XPath=Attribute[value].Value}" />
                <DataGridTextColumn Header="Header2" Binding="{Binding XPath=Attribute[value].Value}" />
                <DataGridTextColumn Header="Header3" Binding="{Binding XPath=Attribute[value].Value}" />
            </DataGrid.Columns>
</DataGrid>

Scenario:

I want to write a Xpath query for each column of the grid such that if the value of tag for Header1 Column is 'Tag1' then the value to be binded to that column should be Value1

So I want a XPath query somewhat like this.
<datagridtextcolumn header="Extending Unit" binding="{Binding XPath=Items/Item[@tag='Tag1']}">
AT the end the value to be binded to the Binding attribute should be Value1 if the Xpath query has 'Tag1'

Similary for other columns
Value to be binded Value2 and XPath query should have tag='Tag2'
Value to be binded Value3 and XPath query should have tag='Tag3'


Hope this clears the scenario.

Thanks, Tapas

You can start with this short article where the use of XPath is demonstrated: http://www.c-sharpcorner.com/UploadFile/mamta_m/binding-xml-to-a-wpf-datagrid[^].
