RadGrid中的文本框由客户端更改

我有一个RadTextbox的GridTemplateColumn。该文本框的值由javascript更改。但是当我点击文本框时，它会变回原始值。

请帮

的JavaScript

<title>Untitled Page</title> 

<script type="text/javascript"> 
    function changeCountry() {    

     var grid = $find('<%=RadGrid1.ClientID %>'); 
     var MasterTable = grid.get_masterTableView();    
     var dataItems = MasterTable.get_dataItems(); 

     var cellCountry = dataItems[0].get_cell("CountryCol"); 
     var txtCountry = $telerik.$(cellCountry).find('input')[0]; 
     txtCountry.value = "New Country";   
    } 
</script>

的.aspx

       <telerik:GridBoundColumn DataField="CR_Country" HeaderText="Branch" Display=false></telerik:GridBoundColumn> 

       <telerik:GridTemplateColumn HeaderText="CR_Country" DataField="CR_Country" UniqueName="CountryCol"> 
        <ItemTemplate>      
         <telerik:RadTextBox ID="txtCountry" runat="server"></telerik:RadTextBox>             
        </ItemTemplate> 
       </telerik:GridTemplateColumn>             

      </Columns> 
      <EditFormSettings> 
       <EditColumn FilterControlAltText="Filter EditCommandColumn column"> 
       </EditColumn> 
      </EditFormSettings> 
     </MasterTableView> 
    </telerik:RadGrid>

.aspx.cs

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
{ 
    if (e.Item is GridHeaderItem) 
    { 
    } 
    if (e.Item is GridDataItem) 
    { 
     GridDataItem dataItem = (GridDataItem)e.Item; 

     RadTextBox txtCountry = ((RadTextBox)dataItem.FindControl("txtCountry")); 
     txtCountry.Text = dataItem["CR_Country"].Text; 

    } 

}

您需要使用Telerik的客户端脚本SET_VALUE函数，而不是纯JavaScript/HTML，即

function changeCountry() {    

    var grid = $find('<%=RadGrid1.ClientID %>'); 
    var MasterTable = grid.get_masterTableView();    
    var dataItems = MasterTable.get_dataItems(); 

    dataItems[0].findControl("txtCountry").set_value("New Country"); 
}
