custom text exact match on client selected ondex changed event

[Hari Prasad]

Hi,

I have combo box, im loading the item on load demand. I have client selected index changed event, if i type exact text(case sensitive) and when i come out of the combobox and clicked on out side of the combobox,onclientselectedindexchanged event is firing. I don't want to fire this event when exact match is found. I want user to select the item from the combobox list then only i want this event to be fire.

I have

MarkFirstMatch

 

="false"

 

Attachment1 is firing the event.
Attachment2 is not firing the event.
Please let me know the solution for this. If this is the default behaviour of the combobox, are there any work arounds for the solution.

Thanks in Advance,
Hari.

Hi,

Try the following Javascript to achieve your scenario.

JS:

<script type="text/javascript" >
   function OnClientBlur(sender, args)
    {
      sender.clearSelection();
    }
</script>

Thanks,
Princy.

Hi Princy,

Thanks for your quick reply.

Is it possible to do without clearing the selection. I have typed "dotnet se" and i will come out of the combobox, then its clearing the combobox item. I would like to be text should exist in the combo box when i come out of the combo box.

Thanks in Advance,
Hari.

Hi HariPrasad,

Yes its possible without clearing the selection as well.
Try the following JS and it worked as expected.First add a asp:hiddenfield to the aspx
aspx:

<asp:HiddenField ID="HiddenField1" runat="server" />

JS:

<script type="text/javascript">
function OnClientBlur()
 {
   var combobox = $find('<%=RadComboBox1.ClientID%>');
   var combotxt = combobox._text;
   var items = combobox.get_items();
   var itemsCount = items._array.length;
   for (var itemIndex = 0; itemIndex < itemsCount; itemIndex++)
   {
      var itemtxt = items._array[itemIndex]._text;
      if (combotxt == itemtxt)
      {
        var hidfield = document.getElementById('<%=HiddenField1.ClientID%>');
        hidfield.value = "1";
      }

    }
 }

function OnClientSelectedIndexChanged()
  {
    var hidfield = document.getElementById('<%=HiddenField1.ClientID%>');
    if (hidfield.value == "1")
     {
       return false;
     }
     else
     {
       //your code......
     }
  }
</script>

Thanks,

It worked. Thanks for your help.
If we type exact match, then Combobox client selected index changed event is firing. Is this the Default behaviour of the Rad Combo Box?

Thanks,
Hari.

Hi HariPrasad,

You can cancel the OnClientSelectedIndexChanging event as follows which doesn't allow to fire OnClientSelectedIndexChanged event of RadComboBox.

JS:

<script type="text/javascript">
    function OnClientBlur() {
        var combobox = $find('<%=RadComboBox1.ClientID%>');
        var combotxt = combobox._text;
        var items = combobox.get_items();
        var itemsCount = items._array.length;
        for (var itemIndex = 0; itemIndex < itemsCount; itemIndex++) {
            var itemtxt = items._array[itemIndex]._text;
            if (combotxt == itemtxt) {
                var hidfield = document.getElementById('<%=HiddenField1.ClientID%>');
                hidfield.value = "1";
            }
        }
    }
    function OnClientSelectedIndexChanging(sender,args) {
        debugger;
        var hidfield = document.getElementById('<%=HiddenField1.ClientID%>');
        if (hidfield.value == "1") {
            hidfield.value = "0";
            args.set_cancel(true);
            return false;
        }
        else {
            //your code......
        }
    }
</script>

Hope this helps.

Thanks,
