For some reason I am unable to hide the drop down on the client. I'm using the following code:

    
            Telerik.Web.UI.RadComboBox.ComboBoxes[0].hideDropDown();

I am able to show the drop down using .showDropDown() with no problem.

In Firefox 2 and 3, hiding it does nothing. There is no JavaScript error, it just ignores the function call.

In IE6 and IE7, I get a JavaScript error in your code. The error occurs inside the _setPosition function, on the line that looks like this:

    
            _169.style[_16a]=_168;

There is definitely a combo box on the screen, and I am able to get a reference to it by using the array above. I proved that by calling get_id(), and it does return the ID of the combo box correctly.

What am I doing wrong? Thanks.

Hello Jeremy T. Fuller,

I just tried with this code:

    
            <script type="text/javascript"> 
        
                    function pageLoad() 
        
                    { 
        
                        Telerik.Web.UI.RadComboBox.ComboBoxes[0].showDropDown();  
        
                        Telerik.Web.UI.RadComboBox.ComboBoxes[0].hideDropDown();  
        
                    } 
        
                </script> 
        
                <form id="form1" runat="server"> 
        
                <asp:ScriptManager ID="ScriptManager1" runat="server"> 
        
                </asp:ScriptManager> 
        
                <div> 
        
                    <telerik:RadComboBox ID="RadComboBox1" runat="server"> 
        
                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                        <Items> 
        
                            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" /> 
        
                            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem2" /> 
        
                            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem3" /> 
        
                        </Items> 
        
                    </telerik:RadComboBox> 
        
                </div> 
        
                </form>

and everything worked normally - without errors.

Could you specify how exactly the problem can be reproduced?
