Webshims Required Field

[Russ]

I am using this framework for validation in my web app.  I'm trying to set a RadComboBox to required using the required attribute.  The problem is that field never identifies as "required" when empty.  I believe the reason is the control is defined as below and I'm adding a required attribute with the following javascript:

$('#ctl00_MainContent_LRS_pi_1_ddlProductCDF_Input').attr('required', 'required');

The issue I believe is related to the fact that ctl00_MainContent_LRS_pi_1_ddlProductCDF_Input is set to readonly.  It works when I allow CustomText using the same code but that's not really what I want.  I can't use the RadDropdownList or regular DropdownList b/c I need separators for items in my dropdown so I'm left with the RadComboBox.  Is there something I'm missing?

I have a demo of the problem but I can't attach it here.

  <div id="ctl00_MainContent_LRS_pi_1_ddlProductCDF" class="RadComboBox RadComboBox_Office2010Blue" style="width:100px;">
 <table summary="combobox" style="border-width:0;border-collapse:collapse;table-layout:fixed;width:100%">
  <tr class="rcbReadOnly">
   <td class="rcbInputCell rcbInputCellLeft" style="margin-top:-1px;margin-bottom:-1px;width:100%;"><input name="ctl00$MainContent$LRS_pi_1$ddlProductCDF" type="text" class="rcbInput radPreventDecorate" id="ctl00_MainContent_LRS_pi_1_ddlProductCDF_Input" value="" style="display: block;" readonly="readonly" tabindex="30" /></td><td class="rcbArrowCell rcbArrowCellRight" style="margin-top:-1px;margin-bottom:-1px;"><a id="ctl00_MainContent_LRS_pi_1_ddlProductCDF_Arrow" style="overflow: hidden;display: block;position: relative;outline: none;">select</a></td>
  </tr>
 </table><div class="rcbSlide" style="z-index:6000;"><div id="ctl00_MainContent_LRS_pi_1_ddlProductCDF_DropDown" class="RadComboBoxDropDown RadComboBoxDropDown_Office2010Blue " style="float:left;display:none;"><div class="rcbScroll rcbWidth" style="width:100%;"><ul class="rcbList" style="list-style:none;margin:0;padding:0;zoom:1;"><li class="rcbItem "></li><li class="rcbItem  rcbSeparator ">Assets</li><li class="rcbItem ">DRS</li><li class="rcbItem ">VPS</li><li class="rcbItem ">VPS/TCPIP</li></ul></div></div></div><input id="ctl00_MainContent_LRS_pi_1_ddlProductCDF_ClientState" name="ctl00_MainContent_LRS_pi_1_ddlProductCDF_ClientState" type="hidden" />
</div>

Changing the RadComboBox to native mode does allow the required attribute to be validated.  The RadDropdownList doesn't correctly validate the required attribute in any mode.  I have a feeling that as part of the changes you are making for migrating the controls HTML5 and CSS3 that these are issues you know about.

Hi Russ,

 
Would you please specify which one of the suggested validations in this on-line demo are you trying to achieve because it is not quite clear from the provided so far information?

Please also refer to this help topic where is show how similar behavior can be done with RequiredFiedValidator and the value of RadComboBox.

If you r scenario is somehow different please elaborate a little bit so we could be more helpful.

Plamen,

While I'm aware that I can use ASP.NET Validators to accomplish the same thing, we are looking at a pure javascript solution.  As part of that the required attribute, as part of the HTML 5 spec, indicates that when that field is set, the value field is updateable and the value field is empty, the form will stop processing and indicate that the field is required. 

The reason for the use of required in our solution is the extra controls and setup it takes for our developers.  By simply placing a required attribute on the field, the validation works without any extra thinking/coding on the developers part.  If you would like I can send you a sample project showing you the issue.

Hello,

 
We have inspected the issue in the support ticket and the desired functionality is working as expected if the MarkFirstMatch="true" property of RadCombobox is set.
