Hi,

I'm using the above client side function, But this is not working..

<script type="text/javascript" language="javascript">

    function SelectionChanged()
    {
        var dropdown = $find('<%=ddlSeaMulti.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.set_currentValue("-Please Select-", true);
    }

   </script>

i cannot see any dropdown list values resetting.. Any suggestion please

Hi pavanpuligandla,

Attached is a sample demonstrating both client and serverside approaches for clearing the selection of WebDropDown. The onchange event of an ASP dropdownlist can be handled (although it would not appear in VS properties) as the control is rendered as a <select> element.

Hope this helps.

Hi,

Thanks alot, It is working fine..I've figured it out at my end where i did wrong.One more issue is i should prevent users from editing the WebDropDown text, I came to know that to achieve this we need to set the property DisplayMode="DropDownList", But wehn i use this, I'm unable to set the CurrentValue as "Please Select" rather the ListItems that were bound from the DB are being selected.

How can i prevent this if i use DisplayMode="DropDownList" or there is any work around to prevent users from entering text in the DropDown if DisplayMode is in DropDown? Either will be fine..

Thanks

The next step would be for a developer to research the issues and confirm my findings or offer some resolution.

Dear Petar,

Many thanks for you concern on the issue we are facing, Sure will update if i get any breakthrough.. Again thanks for the support, Good work and keep going Infragistics!!

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

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,

Any solution for this?? I just want to disable the INPUT TEXTBOX so that users can not even click on the textbox, But this hsould happen when DisplayMode is in DropDown not for DropDownList..

Thanks
