There is a Telerik Rad Combobox which has three events.
OnClientItemRequesting,OnClientItemRequested,OnClientKeyPressing. All the above three events is calling a JS function.

In case of Chrome and Firefox all the three events gets fired on key press and autocomplete opens
In case of all IE only OnClientKeyPressing fire and autcomplete doesn't open

The page doctype is HTML5

Please provide a solution to the above problem

Thanks.

Is there a method to have the toolbar wrap similar to the menu ?

Hi

I'm using Radgrid to build a tree structure with source of objects with parent and child relationship.
I'm also have a ddl in my page.
Each time I change my selection in the ddl I need to load differnet data to my radgrid.
The problem is the when I change the ddl and one of the node is expanded to more that 1 level I got error:

Specified argument was out of the range of valid values.
Parameter
name: ItemHierarchicalIndex Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details:
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: ItemHierarchicalIndex

Source
Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the
exception can be identified using the exception stack trace below.

I guess the problem is- the grid is trying to restore the expanded items on the new data source (which has been changed and the expanded levels in client data may not be valid anymore).

Can u help me with solution?
thanks

Hi All,

i have designed my webpage with a raddropdowntree and a RadComboBox . when im clicking on that raddropdowntree , 'EntryAdded' event will fire and a RadComboBox will load. In this event , the page will be blinking. So that i have trying to avoid that. if i will use RadAjaxManager means, the RadDropDownTree  canot be load and accessible. Anybody tell me the solution that, how to avoid flickering  using Rad in webpage while postback. below is the sample code.
<rad:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
       <rad:AjaxSetting AjaxControlID="rddtArea">
            <UpdatedControls>
                <rad:AjaxUpdatedControl ControlID="rcmbName">
            </UpdatedControls>
        </rad:AjaxSetting>
    </AjaxSettings>
</rad:RadAjaxManager>
<rad:RadSplitter runat="server" ID="RadSplitter1" Width="100%" BorderSize="0" BorderStyle="None"
    PanesBorderSize="0" Height="100" Orientation="Horizontal">
    <rad:RadPane ID="RadPane1" runat="server" Height="100%">
   <rad:RadDropDownTree ID="rddtArea" runat="server" DropDownSettings-CloseDropDownOnSelection="true"

                        Skin="Outlook" DropDownSettings-Height="100" AutoPostBack="true">
                    </rad:RadDropDownTree>
  <rad:RadComboBox ID="rcmbworkflowtemplate" runat="server" DataValueField="MOCID"
                        AppendDataBoundItems="false" DataTextField="MOCTitle" AutoPostBack="true" OnSelectedIndexChanged="rcmbworkflowtemplate_SelectedIndexChanged">
                  </rad:RadComboBox>
  </rad:RadPane>
</rad:RadSplitter>

Hi,
I am using Telerik Rad Ajax Controls  2013 Q1 NET 40 for our website, Technologies, ASP.NET, VB.

I have a .aspx page with a ajaxified RadPanelBar. There is a RadPanelItem in RadPanelBar which contains controls such as texboxes, combo boxes etc. HTML Tables are used to show controls/fields in each panel. The RadPanelBar is ExpandMode="MultipleExpandedItems". I have a RadAJXManager for the panelbar.

The RadPanelItem has a cascading combo, so the first combox "Manufacture" on select populates the second Combo "Model. I have set a OnSelectedIndexChanged="ddManufacturer_SelectedIndexChanged" to call a code behind code, which correctly populates the Model Combo. The problem I have is that once the Model combo has been populated, the PanelBarItem which was expanded seems to collapse after the postback.
 
Here is a aspx code:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadPanelBar1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadPanelBar1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
</telerik:RadAjaxManager>

Protected Sub

        Dim editedItem As GridEditableItem = TryCast(TryCast(o, RadComboBox).NamingContainer, GridEditableItem)

            Dim txtManfu As RadTextBox = DirectCast(RadPanelBar1.FindItemByValue("DeviceDetails").FindControl("txtManufacture"), RadTextBox)
            Dim txtModel As RadTextBox = DirectCast(RadPanelBar1.FindItemByValue("DeviceDetails").FindControl("txtModel"), RadTextBox)

        Dim ddModel As RadComboBox = DirectCast(RadPanelBar1.FindItemByValue("DeviceDetails").FindControl("ddModel"), RadComboBox)

        ddModel.Items.Clear()
        ddModel.DataSource = LoadModel(e.Value)
        ddModel.DataBind()

        Dim Panel1 As RadPanelItem = New RadPanelItem
        Panel1 = RadPanelBar1.FindItemByValue("DeviceDetails")

Do I need to ajaxify the controls inside the panelbaritem?   I have tried several ideas like setting the PersistStateInCookies to true. Also tried to capture the collapse in the RadPanelBar PreRender    to stop the collapse and other ideas from this forum. Any suggestions would be appreciated. Thank you.
                                                                                

I am trying to get the autocompletebox to not select any results from the drop down list of values. It seems as soon as any results are displayed the first result is always selected by default so if you hit enter or click a button to process it will ignore any part string you may have there and instead take the selected value.

I would like the autocompletebox to act more like the google search box for example where no value is selected by default and will instead take your inputted string as the default value.

I have tried using the clientside API to no avail to deselect the item.

Any help would be appreciated.

Hello everyone,

I am using a radGrid to display records of data. I am attempting to implement a RadDropDownList that will alter the displayed data in radGrid based on the value selected. The dropDown list correctly rebinds the data and displays the new set of information. My problem occurs when the user attempts to move to a different page or attempts to sort the information. The grid is rebound to the original dataSource and does not maintain the dropDown selected dataSource. What is the best way to maintain the correct dataSource through page postbacks?

DropDown ASPX:

RadGrid NeedDataSource:

BatchNameSelected (Rebind of DataSource to selected data):

RadGrid PageIndexChanged:


Page_Load:

Question: How do I maintain the selected DataSource through postbacks caused by paging and sorting?

I have been unable to find a solution that pertains to my example and would appreciate any help I can get.

Thanks,
Matt

I have set DisplayUpFolderItem to true in my projects...But it is not working.
I have used AssemblyQualifiedName as my ContentProviderTypeName and has overrided ResolveDirectory as well as ResolveRootDirectoryAsTree.

Please help.

How can we achieve the attached table structure with radgrid control. Basically it needs to contain the grouping by a specific configuration property like (Configuration System Hardware and NE Software, Service and Support etc. which actually consists of various product types grouped together.) on  top of the rows, then followed by Product Type which has to span multiple rows instead of showing on the top of the rows. The same product type has to be displayed again on the next if there are more records of the same product type. similar grouping is applicable for Product Fam column as well. Kindly suggest a best way for achieving the same.
