devExpress GridView中的ComboBox [英] ComboBox in devExpress GridView

问题描述

我在devexpress gridview的一列中使用了组合框（有2个默认值）。如何获取该组合框的选定值？



即，在dx：ASPxGridView控件中，我有这样的组合框

 <   dx：GridViewDataTextColumn     FieldName   =  selectState   标题  =  selectState    VisibleIndex   =  1   >  
 <   dataitemtemplate  >  
 <   dx：ASPxComboBox     ID   =  selectState1      runat   = 服务器   值  ='  <％ #Bind（  selectState）％>'   宽度 < span class =code-keyword> =  70px    EnableCallbackMode   =  true   >  
 <  项目 >  
 <   dx：listedititem    文字  =  on   值  =  on < span class =code-attribute>   /  >  
 <   dx：listedititem    文本  =  off   值  =  off    /  >  
 <   / items  >  
 <   / dx：ASPxComboBox  >  
 <   / dataitemtemplate  >  
 <   / dx：GridViewDataTextColumn  >  

如何获得组合框的选定值？

提前谢谢

解决方案

< blockquote>使用下面的代码从ComboBox中获取所选值。

  for （ int  row =  0 ; row <  gridview1.VisibleRowCount; row ++）
 {
 ASPxComboBox ddlStatus =（ASPxComboBox）gridview1.FindRowCellTemplateControl（row， null ，   ddlStatus）; 
  string  status = ddlStatus.SelectedValue; 
} 

I used combo box(with 2 default values) in one of the column of a devexpress gridview. How to get the selected value of that combo box?

ie, in dx:ASPxGridView control, I have combobox like this

<dx:GridViewDataTextColumn FieldName="selectState" Caption="selectState" VisibleIndex="1" >
                   <dataitemtemplate>
                     <dx:ASPxComboBox ID="selectState1"  runat="server" Value='<%#Bind("selectState") %>' Width="70px" EnableCallbackMode="true" >
                       <items>
                         <dx:listedititem Text="on" Value="on" />
                         <dx:listedititem Text="off" Value="off" />                        
                       </items>                     
                     </dx:ASPxComboBox>
                   </dataitemtemplate>
               </dx:GridViewDataTextColumn>

how to get the selected value of the combo box?
Thanks in advance

解决方案

Use this below code to get the selected value from the ComboBox.

for (int row = 0; row < gridview1.VisibleRowCount; row++)
{
 ASPxComboBox ddlStatus = (ASPxComboBox)gridview1.FindRowCellTemplateControl(row, null, "ddlStatus");
    string status = ddlStatus.SelectedValue;
}
