Question

我们可以将下面的xml中的Fields lastName，fistNname和userName填充到DataGrid视图中，还有一个带有单选按钮的列。这样一个用户可以一次选择一行，我们可以使用字段值＆＃34; userNname＆＃34;进行进一步的交易。

<ConfData>
  <CfgPerson>
    <DBID value="165"/>
    <tenantDBID value="101"/>
    <lastName value="GI"/>
    <firstName value="Sim"/>
    <employeeID value="simulator"/>
    <userName value="SimGI"/>
    <password value="[output suppressed]"/>
    <isAgent value="1"/>
    <isAdmin value="1"/>
    <state value="1"/>
    <isExternalAuth value="1"/>
    <changePasswordOnNextLogin value="0"/>
    <passwordHashAlgorithm value="0"/>
    <PasswordUpdatingDate value="0"/>
  </CfgPerson>
  <CfgPerson>
    <DBID value="257"/>
    <tenantDBID value="101"/>
    <lastName value="Scott"/>
    <firstName value="Mike"/>
    <employeeID value="00116019"/>
    <userName value="scottmp"/>
    <password value="[output suppressed]"/>
    <appRanks>
      <CfgPersonRank>
        <appType value="70"/>
        <appRank value="3"/>
      </CfgPersonRank>
      <CfgPersonRank>
        <appType value="47"/>
        <appRank value="3"/>
      </CfgPersonRank>
      <CfgPersonRank>
        <appType value="49"/>
        <appRank value="3"/>
      </CfgPersonRank>
    </appRanks>
    <isAgent value="1"/>
    <isAdmin value="1"/>
    <state value="1"/>
    <externalID value="Michael.Scott"/>
    <isExternalAuth value="2"/>
    <changePasswordOnNextLogin value="1"/>
    <passwordHashAlgorithm value="0"/>
    <PasswordUpdatingDate value="0"/>
  </CfgPerson>
</ConfData>
