get *only* the text that you typed (and that is allowed)

[David]

i am trying to get the text that i have typed into my radcombobox.

The combobox is defined as :

cmb = New RadComboBox
      cmb.ID = "cmbSearch"
      cmb.ShowDropDownOnTextboxClick = False
      cmb.MarkFirstMatch = True
      cmb.DataTextField = "TextField"
      cmb.DataValueField = "ValueField"
      cmb.ShowToggleImage = False
      ' cmb.AutoPostBack = True

      cmb.Attributes("onkeyup") = "handleKeyPress();"

      If Not Page.IsPostBack Then
          cmb.DataSource = _recipe.getAllStockItems(_security.UserID, _security.DivisionId)
          ViewState("cmbDataSource") = cmb.DataSource
          cmb.DataBind()
      End If
      Master.Menubar.Add(cmb)

now, every time i type something into the box, the 'handleKeyPress' javascript function runs - as you can see in the above code.


this javascript function is defined as:

function handleKeyPress()
{
    var combo = $find('<%=cmb.ClientID%>');

    //  alrt('error');
    document.getElementById('<%=hidAutoComplete.ClientID%>').value = combo._filterText;
    document.getElementById('<%=hidAutoComplete.ClientID%>').blur();
 //   alrt('error');
    <%=Page.ClientScript.GetPostBackEventReference(hidAutoComplete, "Change")%>


}

this is almost ok.
The point that is confusing me is that the 'combo._filterText' gives me my text that i have typed, and this would look like it works.
e.g:
the radcombobox has an item 'david'. i type in 'da' and the radcomobobx autocompletes it to 'david' but combo._filtertext gives me 'da'.
this is correct and how i would expect it to work.

now, if i typed 'daa' (which doesn't exist in the combobox), the combobox stops me from adding this extra 'a' and will autocomplete it to 'david'.
this is also correct. unfortunately, and this is the problem, 'combo._filtertext' shows 'daa'.

is it possible to get just 'da'. that is, only the text i have entered, and that i am allowed to enter?

Hello David,

I am afraid, that the desired typed text could not be access using any property or method of the RadComboBox, since the Text of the RadComboBox is automatically set to the first found match. However, you could compare both string ._filterText and .get_text(), in order to capture the matching substrings.

that you for your advice.
i have added the following, to give me what I need:

var filtText =  String(combo._filterText);
var fullText = String(combo.get_text());
var actualFilterText = '';

for (var i = 0,len = filtText.length; i < len; i++){

    if (filtText[i].toUpperCase() == fullText[i].toUpperCase()){
        actualFilterText += filtText[i];
    }else{
        break;
    }

}
