Lazy Loading

We want to have a drop down of 'equipment types'. This is a fairly big list so we would like to lazy load it. The issue we are having is if we do lazy load you can't restrict what they type.

Is there some kind of work around to get AllowCustomText =false with load on demand?

            <telerik:RadComboBox  Width="556px"  ID="Exp_Code" runat="server" Height="190px" Skin="Sunset" 
        
                                     MarkFirstMatch="true"  EnableLoadOnDemand="true" HighlightTemplatedItems="true" 
        
                                    ItemRequestTimeout="1"  OnItemsRequested="Exp_Code_ItemsRequested" OnItemDataBound="Exp_Code_ItemDataBound" DataSourceID="SqlDataSource1" CollapseDelay="1" ExpandDelay="1">  
        
                                    <HeaderTemplate> 
        
                                        <ul> 
        
                                         <li class="col1">Code</li> 
        
                                         <li class="col2">Nom</li> 
        
                                         <li class="col3">CP</li> 
        
                                         <li class="col4">Ville</li> 
        
                                         <li class="col5">Pays</li> 
        
                                        </ul> 
        
                                    </HeaderTemplate> 
        
                                    <ItemTemplate> 
        
                                        <ul> 
        
                                         <li class="col1"><%# DataBinder.Eval(Container.DataItem, "Tiers") %></li>  
        
                                         <li class="col2"><%# DataBinder.Eval(Container.DataItem, "Nom") %></li>  
        
                                         <li class="col3"><%# DataBinder.Eval(Container.DataItem, "CP") %></li>  
        
                                         <li class="col4"><%# DataBinder.Eval(Container.DataItem, "Ville") %></li>  
        
                                         <li class="col5"><%# DataBinder.Eval(Container.DataItem, "Pays") %></li>  
        
                                        </ul> 
        
                                    </ItemTemplate> 
        
                            <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                         </telerik:RadComboBox>

In my function Page_Load(), I have this code :

    
            Exp_Code.Text =  (Tiers + "      ").Substring(0, 12);

I wish on the function Page_Load(), to go to search the corresponding item text like format in function Exp_Code_ItemDataBound :

    
            protected void Exp_Code_ItemDataBound(object sender, RadComboBoxItemEventArgs e)  
        
                    {  
        
                        e.Item.Text = ((DataRowView)e.Item.DataItem)["Tiers"].ToString() + "        - " + ((DataRowView)e.Item.DataItem)["Nom"].ToString() + " - " + ((DataRowView)e.Item.DataItem)["Ville"].ToString();  
        
                        e.Item.Value = ((DataRowView)e.Item.DataItem)["Tiers"].ToString() + "        - " + ((DataRowView)e.Item.DataItem)["Nom"].ToString() + " - " + ((DataRowView)e.Item.DataItem)["Ville"].ToString();  
        
                    }

Thank you for your help.

[Solved] RadListbox : Undefined is null or not an object onclick when no items

Hi,

I have a listbox that I am populating client side from a list of items that users entered. Initially there are no listbox items, but I set the height of the listbox to 200px. When I click inside the listbox when there are still no items , it displays a javascript error 'undefined' is null or not an object. I believe it happens on the _activateItem client side event of the listbox, but Im not sure how to disable it when there are no items in the list.

Is there a way to trap the _activeitem event on client side or disable it when the list of items = 0 ?

Thanks,
rei

Update grid data from tree drag/drop on client

Hello,

I'm trying to create a drag / drop action that moves a string of text from a tree control to a radgrid.   The value from the tree control needs to be placed into a field in the datagrid, while the datagrid is in insert or edit mode.

I'm hoping for a simple client side solution. I don't want to commit the row to the database especially in the event the user is not ready to save it yet.

I have hold of my tree value in a variable in javascript

            args.get_sourceNode().get_value()

I also have a hold of the control i want to update

            var row = selectedRows[i];
            var cell = MasterTable.getCellByColumnUniqueName(row, "PageLink");
            alert(cell.innerHTML);

I just need the magic that will help me push the value into the cell.

Any ideas a MUCH appreciated.
