RadComboBox and case sensitive text search

[Miłosz Cechnicki]

Hi,
is it possible, to force the RadComboBox to search values with case sensitive mode?
In our scenario 'titel' and 'TITEL' and 'Titel' are totally different values.

The RadComboBox definition looks like:

<telerikInput:RadComboBox x:Name="ctrlParameterValue" Margin="8,0,8,8" IsEditable="True" IsTextSearchEnabled="True" TextSearchMode="StartsWith" Style="{StaticResource AplusCRadComboBoxStyle}" />

Thank you for your help.

Hello Miłosz,

RadComboBox does not support case sensitive search yet, but this looks like an "easy" feature, that could be implemented soon. I will do my best to provide it for the incoming internal build this Friday.

Kind regards,

has this feature been added to RadComboBox WPF ?

[Valeri Hristov]

Hi Gabriel,

Yes, the latest service pack has this feature. To use it you should set TextSearchMode=StartsWithCaseSensitive or ContainsCaseSensitive.

I know this is an old thread but I would like to request that this feature be added to the ASP.NET AJAX controls both server and client side.

Hello Corey,

Could you please be a bit more specific - which function do you suggest to be case-sensitive: marking the first match, filter, or both?

Kind regards,

What I'd like is for radComboBox.findItemByText to be optionally case insensitive.  Here's what I built to handle this:

function findComboItemByText(combo, text, caseInsensitive)
{
    if (combo && combo.get_items)
    {
        if (!caseInsensitive)
        {
            return combo.findItemByText($.trim(text));
        }
        else
        {
            var items = combo.get_items();

            var searchText = $.trim(text.toLowerCase());
            for (var i = 0; i < items.get_count(); i++)
            {
                var item = items.getItem(i);

                if ($.trim(item.get_text().toLowerCase()) == searchText)
                    return item;
            }

            // no item found
            return null;
        }
    }
}

Similar functionality could also be useful on the server side.

In our scenario, we present the user a list of items to choose from and the ability to add another item if what they want is not in the list.  If they add a new item, we try to match it to an existing value.  If a match is found, we select that match otherwise we add a new item to the list and select it.

Hello Corey,

Thank you for the clarification.

I logged this into our backlog, so future versions of RadComboBox for ASP.NET AJAX will have the feature.

I also updated your Telerik points for the suggestion.

Has this functionality "CaseInsensitive Search" been implemented yet?

I just added a RadComboBox to my asp.net winform.  It has MarkFirstMatch="true",  Filter="StartsWith" and 
IsCaseSensitive="False".  It is not case sensitive for most letters (15 in the out list of items), but others require that I enter a capital letter (A, E, L, S).  Any suggestions?

Hello Jerry,

Could you specify which version of our controls are you currently using?

Hi,

How do I make radcombobox NOT case sensitive. Ignore if the list items are Lower or Upper case and return the result. I tried IsCasesensitive ="false" but no use. 

 

<telerik:RadComboBox ID="cmbPlant" runat="server" AutoPostBack="true" CausesValidation="false" EmptyMessage="Select a Plant" Filter="Contains" Font-Size="14px" MarkFirstMatch="true"  Skin="Black"  IsCaseSensitive="false" >                                 </telerik:RadComboBox>

[Peter Milchev]

Hello Kiran,

The IsCaseSensitive property is responsible for the autocomplete on the client-side, i.e. client-side filtering: 

//
// Summary:
//     Gets or sets a value that indicates whether the combobox autocompletion logic
//     is case-sensitive or not.
[Bindable(false)]
[Category("Behavior")]
[ClientControlProperty]
[ClientPropertyName("isCaseSensitive")]
[DefaultValue(false)]
public bool IsCaseSensitive { get; set; }

If the filtering is server-side, then the database query itself should be configured so that it disregards the case sensitivity. 

Here is a screencast demonstrating the behavior of the following markup using the latest version of the Telerik UI for ASP.NET AJAX controls: http://somup.com/cqifQPecxs

<telerik:RadComboBox ID="cmbPlant" runat="server" AutoPostBack="true" CausesValidation="false" EmptyMessage="Select a Plant" Filter="Contains" Font-Size="14px" MarkFirstMatch="true" Skin="Black" IsCaseSensitive="false">
         <Items>
              <telerik:RadComboBoxItem Text="Item 1" />
              <telerik:RadComboBoxItem Text="Item 2" />
              <telerik:RadComboBoxItem Text="Item 3" />
              <telerik:RadComboBoxItem Text="Item 4" />
          </Items>
      </telerik:RadComboBox>

If the issues persist, please open an official support ticket with a sample runnable project using dummy data that we can investigate locally.
