            //unselect and inactivate the selected items
            while (dropdown.get_selectedItems().length > 0) {
                dropdown.get_selectedItems()[0].inactivate();
                dropdown.get_selectedItems()[0].unselect();
            }
            //set some default value in the dropdown's input field
            ig_controls.WebDropDown1._elements["Input"].value = "Default value";

Where should i include this script? In InputKeyDown event or what? Please let me know..

Thanks

Hi pavanpilugandla,

Thank you for your reply.

The above code may be used in the SelectionChanged function previously used as the handler for the clienside onchange event of the ASP dropdownlist.

Please let me know if this helps.

Hi,

This worked fine, But i dont want to give any clickable functionality on the dropdown, When i used the above script, and pressed HOME and END keys in the keyboard, Eventhough there are values selected in the dropdown were set to Please Select.

I'm using this function in InputKeyDown function..

<script language="javascript" type="text/javascript">
         function ddlCBT_InputKeyDown(sender, eventArgs) {
             var dropdown = $find('<%=ddlCBT.ClientID %>');
             //unselect and inactivate the selected items
//             while (dropdown.get_selectedItems().length > 0) {
//                 dropdown.get_selectedItems()[0].inactivate();
//                 dropdown.get_selectedItems()[0].unselect();
//             }

             //set some default value in the dropdown's input field
            
             dropdown._elements["Input"].value = "-Please Select-";

         }
     </script>

Hi pavanpuligandla,

Apologies for the delayed response.

I am unsure of the issue your are describing in your last, however after examining the matter further, in your scenario it may be more convenient to set the input element of the dropdown to be readonly upon  initializing the WebDropDown. This may be done using something similar to:

function WebDropDown1_Initialize(sender, eventArgs)
{
    sender._elements["Input"].readOnly = true;
}

Hope this is helpful.

Hi,

Thanks for the comeback..

This is working fine, But the items which are being selected are now deselected.. I got an idea here like,

after initialization event, we also need to write inputkeydown event like below as an example

function ddlSerLine_InputKeyDown(sender, eventArgs)

{
             var dropdown = $find('<%=ddlSerLine.ClientID %>');
             while (dropdown.get_selectedItems().length > 0)
             {
                 dropdown.get_selectedItems()[0].inactivate();
                 //dropdown.get_selectedItems()[0].unselect();
             }

             //set some default value in the dropdown's input field
             dropdown._elements["Input"].value = "-Please Select-";
         }

     function ddlSerLine_Initialize(sender, eventArgs)
         {
            sender._elements["Input"].readOnly = true;
         }

Once when the dropdown has been initialized, then the input box will be read only, when user tries to press the key then in InputKeyDown event we need to hold the selection, But in the above code, if the items are selected we are deselecting and deactiviting 'em, Instead of that i need to hold the selected values..

I hope you are clear on my issue..

Thanks

Petar Ivanov"]After consulting with our developers regarding this matter it was determined that the behavior is most likely related to a development issue (as your requirement should be achievable by only setting EnableCustomValues to false which currently still allows editing through the delete and backspace buttons).  In order to ensure that the matter will receive attention I have logged this behaviors in our internal tracking system with a Development IDs 111865. The next step would be for a developer to research the issues and confirm my findings or offer some resolution.

Dear Petar,
