ComboBox SelectedIndex always -1 or 0

I've got two comboboxes with two objectdatasources:

    
            <telerik:RadComboBox ID="RadComboBoxConnection" runat="server" Height="200px" Width="300px" 
        
                    Filter="Contains" MarkFirstMatch="true" ChangeTextOnKeyBoardNavigation="false" AllowCustomText="false" 
        
                    DataSourceID="ObjectDataSourceConnection" DataTextField="DatabaseFriendlyName" DataValueField="ImportConnectionId" AutoPostBack="true" EnableViewState="true"> 
        
            </telerik:RadComboBox> 
        
            <telerik:RadComboBox ID="RadComboBoxObject" runat="server" Height="200px" Width="300px" 
        
                    Filter="Contains" MarkFirstMatch="true" ChangeTextOnKeyBoardNavigation="false" AllowCustomText="false" 
        
                    DataSourceID="ObjectDataSourceObject" DataTextField="ObjectName" DataValueField="ImportObjectId" AutoPostBack="true" EnableViewState="true" OnSelectedIndexChanged="RadComboBoxObject_OnSelectedIndexChanged"> 
        
            </telerik:RadComboBox> 
        
            <asp:Literal ID="litMessage" runat="server" /> 
        
            <asp:ObjectDataSource ID="ObjectDataSourceConnection" runat="server"  
        
                TypeName="Ams.Web.BackOffice.ImportConnectionAdapter"  
        
                DataObjectTypeName="Ams.Core.DomainObject.ImportConnection"  
        
                OldValuesParameterFormatString="original_{0}" 
        
                ConflictDetection="CompareAllValues" 
        
                SelectMethod="SelectImportConnection" /> 
        
            <asp:ObjectDataSource ID="ObjectDataSourceObject" runat="server"  
        
                TypeName="Ams.Web.BackOffice.ImportObjectAdapter"  
        
                DataObjectTypeName="Ams.Core.DomainObject.ImportObject"  
        
                OldValuesParameterFormatString="original_{0}" 
        
                ConflictDetection="CompareAllValues" 
        
                SelectMethod="SelectImportObject"> 
        
                    <SELECTPARAMETERS> 
        
                        <asp:ControlParameter Name="aImportConnectionId" PropertyName="SelectedValue" ControlID="RadComboBoxConnection" /> 
        
                    </SELECTPARAMETERS> 
        
                </asp:ObjectDataSource>

The first combobox I have no problems with. I can selected any entry, and on postback it retains its values.
The second combobox however, when selecting a new item, it loses its value every time. Page_Init its SelectedIndex is -1. Page_Load, always 0!! Even when declaring OnSelectedIndexChanged, still 0. ALWAYS 0 or -1!
Any ideas? Thanks in advance.
PS. Also found something really quirky. I can select an entry, then if I deselect (lose the focus of the second combobox) it reverts to the SelectedIndex = 0.

Issue with RadEditorMoss v5.5.1.0

We've updated the ToolsFile.xml to include the following class and css Files.
<classes>

   <class name = "Table- Download" value=".table" />
    <class name = "Bullet" value=".bullet" />
</classes>

<cssFiles>
    <item name="/Style Library/styles.css" />
   
   <item name="/Style Library/ToolsFile.css" />
</cssFiles>

Everything works fine in IE, but when we test it in Firefox and Chrome the "Table- Download" style is not available from the drop down.

Hope to hear from you soon.
Thanks,
Fu Yuen

Thanks.

Alternating Color Scheme

Hey Telerik,

In using a Timeline scheduler, I am utilizing two different groups. That being said, is there a way for the color of events to be different for each group?

Can't sort on my data column

I am creating a RadGrid and initially assigning the sortExpression to use the data column, "Plcmt Date" as its FieldName:

<telerik:GridSortExpression FieldName="Plcmt Date" SortOrder="Ascending" />

</SortExpressions>

the column seems to be set up correctly:

<telerik:GridBoundColumn HeaderText="Plcmt Date" UniqueName="PlacementDate" HeaderTooltip=""

SortDescImageUrl="../RadControls/Grid/Skins/Default/SortDesc.gif" SortAscImageUrl="../RadControls/Grid/Skins/Default/SortAsc.gif"

DataField="Plcmt Date" SortExpression="Plcmt Date" AllowSorting="true" FooterText="Grand Total">

but I am getting this error:

Error serializing value 'Plcmt Date ASC' of type 'Telerik.Web.UI.GridSortExpression.'

Is it because there is a space in the column name or something? I've looked all over the site and don't see anything about restrictions on column names that can be used for sorting.

Error: Exporting Grid Results to HTML

Hello Telerik Team,

Please help me fix this issue.
I am displaying RadGrid with paging enabled.
I would like to export all the results to HTML. But coming across this issue: error.png (attached)

Error: Script control 'PageSizeComboBox' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

I have referred this blog but I am not able to understand how to handle this issue. Please guide me to resolve this issue.

ps: It works if I disable the Paging. I would like to have this work with paging Enabled. Thanks.

Thanks,
Smith

Client-side validation issue (Should be simple?)

Consider the following javascript (inside schedulerFormCreated function for advanced form example):

    
             $telerik.$(".rsAdvResourceValue").each(function(i) { 
        
                                if (this.id.match("cboPrimaryClient") != null) 
        
                                    priCliCbo = this.id; 
        
                            }); 
        
                            if (priCliCbo != null) { 
        
                                priCliCboBox = $find(priCliCbo); 
        
                                $telerik.$(".rsAdvEditSave").bind("click", function(e) { 
        
                                priCliCboBox = $find(priCliCbo); 
        
                                    if (priCliCboBox.get_selectedItem() == null) { 
        
                                        alert("Please select a Primary Client"); 
        
                                        return false; 
        
                                    } 
        
                                    if (priCliCboBox.get_selectedItem().get_text() == "") { 
        
                                        alert("Please select a Primary Client"); 
        
                                        return false; 
        
                                    }

This works GREAT for the one dropdown box on the page, but NO MATTER WHAT I try to get access to the textboxes on there - I get null. I have even firebugged the id's and tried direct references - nothing. Also - attempted to add regular ASP:RequiredFieldValidators in the ascx as those that exist in the sample. This is great, until they validate and the control comes back blank with left pointing arrows in the date picker boxes. I have looked at every example I can find via search and don't seem to see anywhere that simple client-side validation can be done with this.

Scroll to top of page on PageIndexChanged?

Hi,

I have a radgrid with paging at the top and bottom and want the page to scroll back to the top when the page is changed (expecially from the bottom paging links).

I have tried adding the following code, but something inside the radgrid code is stopping it from working as it does on a regular asp.net button.

    
            Protected Sub RadGrid1_PageIndexChanged(ByVal source As Object, ByVal e As Telerik.Web.UI.GridPageChangedEventArgs) Handles RadGrid1.PageIndexChanged  
        
                    ScriptManager.RegisterStartupScript(Me.Page, Me.GetType(), "Scroll", "scroll(0,0); ", True)  
        
                End Sub

Is there another way of achieving this? Or a way of getting my code to work?

Thanks in advance

[Solved] Treeview validation

This should be pretty straightforward, but for some reason, I cannot get treeview to validate properly: the required field validator fails to see when a node is checked, even if ALL nodes are checked. This is a sample code:

    
                <asp:ValidationSummary ID="ValidationSummary1" runat="server" HeaderText="Please review the following errors:" ShowMessageBox="True" ShowSummary="false" DisplayMode="BulletList" /> 
        
                <telerik:RadTreeView ID="RadTreeViewStates" runat="server" CheckBoxes="true" CheckChildNodes="true" TriStateCheckBoxes="true" LoadingMessage="Loading states" Skin="Office2007"> 
        
                    <Nodes> 
        
                        <telerik:RadTreeNode Checkable="true" Text="All States" Expanded="true"> 
        
                            <Nodes> 
        
                                <telerik:RadTreeNode Checkable="true" Text="Northeast"> 
        
                                    <Nodes> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="CT" Value="CT"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="MA" Value="MA"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="ME" Value="CT"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="NH" Value="CT"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="NY" Value="CT"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="PA" Value="CT"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="RI" Value="CT"></telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode Checkable="true" Text="VT" Value="CT"></telerik:RadTreeNode> 
        
                                    </Nodes> 
        
                                </telerik:RadTreeNode>                   
        
                            </Nodes> 
        
                        </telerik:RadTreeNode> 
        
                    </Nodes> 
        
                </telerik:RadTreeView> 
        
                <asp:RequiredFieldValidator ID="rvRadTreeViewStates" runat="server" ErrorMessage="Please select at least one state" Display="Dynamic" ControlToValidate="RadTreeViewStates">*</asp:RequiredFieldValidator> 
        
                <asp:Button ID="ButtonSaveSearch" runat="server" Text="Save"  />

The above is similar to the Validation Selection demo. Am I missing something?

Thanks,

Ivan
