1) focus the ComboBox
2) press C
- Camembert Pierrot is selected
- JAWS pronounces "c" and "Camembert Pierrot"
- Camembert Pierrot is selected
- JAWS pronounces "c"

To maintain accessibility consistency with normal HTML select comboboxes, we need the RadComboBox to support the Home and End keys to jump to the 1st and last item respectively. Currently, it just moves the text cursor to the start/end of the textfield. If the change can't be made globally, can a new property be set to control this behavior? Ideally too, Page Up/Down can jump multiple items at a time. Currently, it scrolls the page. See a 2009 forum post too (from someone else): http://www.telerik.com/forums/radcombobox-home-end-page-up-page-down-keys I see the other keyboard shortcuts listed here: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/keyboardsupport/defaultcs.aspx Per Anton: The keyboard support is specification is implemented according to the article (https://www.w3.org/TR/2013/WD-wai-aria-practices-20130307/#combobox) which is why there is no support for these keys. We would like to request these additional keys be supported anyway. [From ticket 1083598]
In WebService binding scenario, the text of the items is not encoded and HTML code might get executed.
In Server-side Load on Demand binding this is not observed.
The following code can be used as a temporary workaround for WebService binding scenario:
<telerik:RadComboBox runat="server" ID="CB" AllowCustomText="true" HighlightTemplatedItems="true" EnableViewState="false" CheckBoxes="true" EnableLoadOnDemand="true" OnItemsRequested="CB_ItemsRequested" ></telerik:RadComboBox>Specifically, note that CheckBoxes is true.
In combo box once a value is selected there is no option to clear the selection. We can have an additional button outside the combo box to achieve the same.
This will require some additional coding.
Since this is a regular scenario why can't there be a property within the RadCombo Box that makes clear selection button visible next to the combo box drop-down button and does the task of clearing the selection?
Hello, Here is how i bind the dropdown. when i trype anything in dropdown it only search based on product code, but i also want search to perform on product code, Product name and wood type code. Please let me know how can i achieve same. <telerik:RadComboBoxDataSourceID="SqlDataSource1"DataTextField="ProductCode"DataValueField="idxProductPriceID"EnableAutomaticLoadOnDemand="True"ItemsPerRequest="10"ShowMoreResultsBox="true"EnableVirtualScrolling="true"AutoPostBack="true"OnSelectedIndexChanged="drpProduct_SelectedIndexChanged"EnableLoadOnDemand="true"EnableScreenBoundaryDetection="true"HighlightTemplatedItems="true"MarkFirstMatch="false"Filter="Contains"ID="drpProduct"DropDownAutoWidth="Enabled"Width="100px"runat="server"><HeaderTemplate><tablestyle="width: 100%"cellspacing="0"cellpadding="0"><tr><tdstyle="width: 20%;">Product Code </td><tdstyle="width: 40%;">Product Name </td><tdstyle="width: 40%;">Wood Type Code </td></tr></table></HeaderTemplate><ItemTemplate><tablestyle="width: 100%"cellspacing="0"cellpadding="0"><tr><tdstyle="width: 20%;"><%#DataBinder.Eval(Container.DataItem, "ProductCode")%></td><tdstyle="width: 40%;"><%#DataBinder.Eval(Container.DataItem, "ProductName")%></td><tdstyle="width: 40%;"><%#DataBinder.Eval(Container.DataItem, "WoodTypeName")%></td></tr></table></ItemTemplate></telerik:RadComboBox><asp:SqlDataSourcerunat="server"ID="SqlDataSource1"ConnectionString="<%$ ConnectionStrings:Default %>"ProviderName="System.Data.SqlClient"SelectCommandType="StoredProcedure"SelectCommand="3_ProductList_Select"></asp:SqlDataSource>
A possible workaround would be tweaking the ItemRequestTimeout property of the ComboBox <telerik:RadComboBox ItemRequestTimeout="380" runat="server" ... > ... </telerik:RadComboBox>
The ComboBox pop-up is moving over the page during scrolling in mobile Chrome (Android device). The problem is occurres both in scrolled or zoomed elements. *The same issue is reproducible also in the SkinChooser. Steps to reproduce: 1. Run the following code in in mobile Chrome: <telerik:RadSkinManager ID="RadSkinManager1" runat="server" ShowChooser="true" PersistenceMode="ViewState" RenderMode="Auto" Skin="Telerik"> </telerik:RadSkinManager><br /><br /> <telerik:RadComboBox ID="cb1" runat="server" AutoPostBack="true"> <Items> <telerik:RadComboBoxItem Text="January" Value="1" /> <telerik:RadComboBoxItem Text="February" Value="2" /> <telerik:RadComboBoxItem Text="March" Value="3" /> <telerik:RadComboBoxItem Text="April" Value="4" /> <telerik:RadComboBoxItem Text="May" Value="5" /> <telerik:RadComboBoxItem Text="June" Value="6" /> <telerik:RadComboBoxItem Text="July" Value="7" /> </Items> </telerik:RadComboBox> 2. Tap over the combo in order to show its dropdown 3. Drag to scroll the page to the left Result: The dropdown pop-up is moving over the page.
Given a RadComboBox with search, if the user enters some search text and then clicks on one of the filtered entries in the dropdown list the validation event is fired as the entry box loses focus and results in a 'false' return from validation as it uses the 'Text' property which is the search string. Validation is then refired as a result of clicking on the entry. However, the initial 'false' return can cause unwanted behaviour in code that depends on the validation event. I can supply a sample project demonstrating the problem, but it needs more than the 10 MB upload limit.
"Loading..." text in Combobox with Virtual Scrolling is visible on first set of items loading. It shows first time "Loading..." text. on scrolling it loads items from PageMethods/WebService but "Loading..." text it not visible i.e. because it is first <LI> item so it is not visible. Instead of first <LI> item, it should be at position where it always display while loading more items. same issue is also in telerik demo website : http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
This error comes up often for this control and workarounds have been discussed and posted. See below http://www.telerik.com/forums/radcombobox-error-selection-out-of-range-parameter-name-value http://www.telerik.com/forums/selection-out-of-range-excpetion http://www.telerik.com/forums/selection-out-of-range-parameter-name-error-need-to-be-able-to-set-values-that-don-t-exist-in-the-combobox http://www.telerik.com/forums/selection-out-of-range-parameter-name-value http://www.telerik.com/forums/selection-out-of-range-parameter-name-value-radcombobox-in-radgrid http://www.telerik.com/forums/radcombobox-selection-out-of-range-error The feature request is the following: 1. Add an Attribute to the RadComboBox, RadDropdownList (and any other controls that suffer from this issue). 2. Let's call the Attribute -- AppendIfSelectedValueMissing. 3. This attribute would be a boolean (True / False). Default is FALSE. 4. If AppendIfSelectedValueMissing=True then when the value of record is being Databound to a RadComboBox, RadDropDownList, etc. A check (or Try/Catch) would occur to ensure that the Value exists in the DataSourceList and if it does NOT exist in the list then the SelectedValue would be Appended to the List. Thus, eliminating the "Selection out of range, Parameter, Value" error. This occur often because some lists get changed over time; however, the historical data may have a value that is no longer on the list -- thus triggering the error. For example, let's say we ask for a user's Favorite Color. Our original list was: Red, Green, Blue but for some reason -- management, changing user requirements, etc. the new list is Red, Orange, Blue Now, if we DataBind a RadComboBox to a historical record with Green as value, we get the "Selection Out of Range" errror. What I am proposing is -- if we set the AppendIfSelectedValueMissing = True then databinding to a historical record with Green would have the following occur. List from DB --- Red, Orange, Blue SelectedValue -- Green AppendIfSelectedValueMissing New List for Ctrl -- Red, Orange, Blue, Green Thus, the error goes away, the historical data can stay the way it is and the lists can adjust their choices over time. All good for everyone!!! Thanks for your consideration.
