Hello,

I have not been able to locate a solution to my problem, so thought I'd post it here.

I have created a class that extends the RCB (i.e public class MyComboBox : Telerik.Web.UI.RadComboBox { ...}). Code omitted though it does do a fair bit of company centric implementation.

I have placed two of these controls on a page, one dynamically loading items the other statically. I have no issues with the dynamically loaded CB, Including the extended functionality, all works great.

Though the statically loaded CB does not render the items, everything else seems fine!

Statically loaded:

This displays an empty ComboBox.

Page code:

                    <cc1:MyComboBox ID="dl2" TabIndex="7" BackColor="White" Width="72px" runat="server"         
                        Font-Size="12px" Font-Names="Arial" CssClass="txtBox">                                             
                        <Items>                                 
                            <telerik:RadComboBoxItem Selected="True" Value="N/A"></telerik:RadComboBoxItem>         
                            <telerik:RadComboBoxItem Value="Male" Text="Male"></telerik:RadComboBoxItem>         
                            <telerik:RadComboBoxItem Value="Female" Text="Female"></telerik:RadComboBoxItem>         
                        </Items>                     
            </cc1:MyComboBox>         

Dynamically loaded:

This is fine, the items are added in the code behind

                    <cc1:MyComboBox ID="dl1" TabIndex="1" BackColor="White" Width="160px" runat="server"         
                        Font-Size="12px" Font-Names="Arial">         
            </cc1:MyComboBox>         

I have tried a simple extensions of the RadComboBoxItemCollection and RadComboBoxItem hoping that would help, but it did not.

                     public class MyComboBoxItem : RadComboBoxItem         
                {         
                    public MyComboBoxItem()         
                    {         
                    }         
                }         
                     
                public class MyComboBoxItemCollection : RadComboBoxItemCollection         
                {         
                             
                    public MyComboBoxItemCollection():base(null)         
                    {         
                                              
                    }         
                     
                    public MyComboBoxItemCollection(Control parent):base(parent)         
                    {         
                     
                    }         
                }         

                    <cc1:MyComboBox ID="dl2" TabIndex="7" BackColor="White" Width="72px" runat="server"          
                        Font-Size="12px" Font-Names="Arial" CssClass="txtBox">                                              
                        <Items>                                  
                            <cc1:MyComboBoxItem  Selected="True" Value="N/A"></cc1:MyComboBoxItem>          
                            <cc1:MyComboBoxItem Value="Male" Text="Male"></cc1:MyComboBoxItem>          
                            <cc1:MyComboBoxItem Value="Female" Text="Female"></cc1:MyComboBoxItem>          
                        </Items>                      
            </cc1:MyComboBox>          

I have a feeling I am missing one vital but simple requirement, though cannot for the life of me see what it is.

Any help would be appreciated.

Cheers.

[Solved] Setting menu item css style onclientitempopulated event

I'm sure I'm missing something simple here...

I have menu where the root nodes are loaded in the code behind and the child menu items are loaded on demand via a web service. I need to apply a different css style to child menu items of a specific root item. I thought I could do this on the OnClientItemPopulated event with the following code:

    
                        function itemPopulated(sender, eventArgs)  
        
                        {  
        
                            var item = eventArgs.get_item();  
        
                            if (item && item.get_value() == "myValue")  
        
                            {  
        
                                for (var i=0; i < item.get_items().get_count(); i++)  
        
                                {  
        
                                    item.get_items().getItem(i).set_cssClass("myCssClass");  
        
                                }  
        
                            }  
        
                        }

However, I noticed that the style for the items, as the menu is expanding and when it is open, is the default style and that my applied style only takes effect as the menu is closing. What am I missing?

Problem loading Aspose.Form control

Hi,

I'm evaluating Telerik RadControls in a web application. On a RadComboBox change I display another third party control (Aspose.Form) that show my InfoPath forms. I need to view them and on Save button on my page, I want to save that form. However I'm just stuck just getting it loaded on dropdown change event. I get this message:

"Error: Sys.WebForms.PageRequestManagerServerErrorException: Multiple controls with the same ID 'x0' were found. FindControl requires that controls have unique IDs" as shown in the attachment.

My usage of controls in .aspx is:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<telerik:AjaxSetting AjaxControlID="RadComboBox1">

<telerik:AjaxUpdatedControl ControlID="XmlFormView1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadComboBox ID="RadComboBox1" runat="server"

AutoPostBack="true"

onselectedindexchanged="RadComboBox1_SelectedIndexChanged"

Label="Please select a form:" Width="200px">

<Items>

<telerik:RadComboBoxItem Text="" Value="" />

<telerik:RadComboBoxItem Text="AST Monthly Inspection Checklist" Value="1" />

<telerik:RadComboBoxItem Text="Book1PMIQAL CHECKLIST" Value="2" />

</Items>

</telerik:RadComboBox>

And in codebehind, I have:

protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

//Getting error on DDL change:

//Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Multiple controls with the same ID 'x0' were found. FindControl requires that controls have unique IDs.

try

{

XmlFormView1.Controls.Clear();

XmlFormView1.Reset();

if (int.Parse(RadComboBox1.SelectedItem.Value) > 0)

{

XmlFormView1.XsnLocation = Server.MapPath("Forms/" + RadComboBox1.SelectedItem.Text + ".xsn");

XmlFormView1.XmlDataString = GetFormDataByID(int.Parse(RadComboBox1.SelectedItem.Value));

}

XmlFormView1.RefreshData();

}

catch (Exception)

{

throw;

}

Sample project can be sent on request so that you can reproduce it.

Thank you,

Displaying data in the Same Format (Maintain Screen)

Hello everyone,

I am using a RadEditor for a small messaging system. However when the user clicks my maintain screen it brings back the data. However the data is not in the same format as they saved it in. Such as spacing, paragraphs, bold, italics, etc. Kind of like these forums, I want to be able to hit edit post or Manage button and comes back with the exact format that the user entered before. Can anyone provide me some assistance. It would be greatly appreciated.

Thanks,
Tommy

Telerik RadGrid PageSize and client-side binding

Hello,

I'm binding on the client-side using declarative binding. Everything works great. The only issue is when I try to set the page size in the master table view markup as:

<MasterTableView ... PageSize="25" />

I am not using custom paging. When this runs, the grid doesn't show the pager. When I remove this and use tableView.set_pageSize(25), it works fine.

Any ideas why? I'm using the latest telerik, 2010.1.415

Thanks.
