验证包含Treeview的组合框 [英] validation of combobox that include treeview

问题描述

此验证无效，因此如何验证是否选择了树视图?

 <   td  > ; 
                   <   setsRC:SRadComboBox     ID   ="   runat   服务器"  TabIndex    3" 
                                            OnClientDropDownOpened   ="  高度   450" 宽度  ="  
 
                                            ClientIDMode   ="   InitialValue    <％ $资源:PayrollResources，SelectValue ％> " <   ItemTemplate  > 
                           <   div     ="   divTreeInCombo" <   setsRC:SRadTreeView     ID   ="   runat   服务器" 宽度   100％" 高度  ="  
 
                     span>                                                OnClientNodeClicked   ="  nodeClicking"  ClientIDMode   ="  > 
                                   <  数据绑定 > 
                                       <   telerik:RadTreeNodeBinding    展开  ="  / <  /DataBindings  > 
                               <  /setsRC:SRadTreeView  > 
                           <  /div  > 
                       <  /ItemTemplate  > 
                       <  项目 > 
                           <   setsRC:SRadComboBoxItem    文本  ="  / <  /Items  > 
                   <  /setsRC:SRadComboBox  > 
               <  /td  > 
               <   setsTB:SValidRequiredFieldValidator     ID   ="   runat   服务器"  ControlToValidate    rcbOrganizationUnitWithTemplate" 
                                  ="   MessageLabel" 展示  ="     ErrorMessage   =" <％ $资源:，rfvOrganizationUnit.ErrorMessage  
 
                                      ="   &％; span> $资源:PayrollResources，WarningIcon ％> " 初始值  =" < ;％ $资源:PayrollResources，SelectValue ％> " 
                                      ="   vgAccountingDesign" / >  

解决方案

资源:PayrollResources，SelectValue ％> " < ItemTemplate > < div =" divTreeInCombo" < setsRC:SRadTreeView ID =" runat 服务器" 宽度 100％" 高度 =" span> OnClientNodeClicked =" nodeClicking" ClientIDMode =" > < 数据绑定 > < telerik:RadTreeNodeBinding 展开 =" / < /DataBindings > < /setsRC:SRadTreeView > < /div > < /ItemTemplate > < 项目 > < setsRC:SRadComboBoxItem 文本 =" / < /Items > < /setsRC:SRadComboBox > < /td > < setsTB:SValidRequiredFieldValidator ID =" runat 服务器" ControlToValidate rcbOrganizationUnitWithTemplate" =" MessageLabel" 展示 =" ErrorMessage =" <％

资源:，rfvOrganizationUnit.ErrorMessage =" <％

资源:PayrollResources，WarningIcon InitialValue <％

this validation not work so how can i validate if the tree view is selected ??
