dropdown button not working

[Michael Tissington]

I have a RadComboBox inside a RadPanel (ASP.NET)
I can click on the text area and the drop down appears, however if I click on the drop down button image, nothing happens.

Any ideas please ?

<telerik:RadComboBox ID="What" runat="server" Width="130px" OnClientSelectedIndexChanging="SelectedIndexChanging" TabIndex="1">

<Items>

<telerik:RadComboBoxItem runat="server" Text="Job Code" />

<telerik:RadComboBoxItem runat="server" Text="Job Title" />

<telerik:RadComboBoxItem runat="server" Text="Status" />

<telerik:RadComboBoxItem runat="server" Text="Tracking Number" />

</Items>

</telerik:RadComboBox>

Hello Michael Tissington,

I tried to reproduce the problem at our side, but to no avail.

Attached, please find a small and running project on the matter. Download it and give it a try.

What am I missing?

You ask what are you missing ... ?

I'n my case I have EnableEmbeddedScripts = false and I'm using a copy of the Vista skin - I have not yet modified the skin.

[Nikolay]

Hi Michael Tissington,

Did you mean the EnableEmbeddedSkins property?
If you disable this property, you will have to include the skin in your project.

I prepared a small and running project for you.

Please download the files and give them a go.

Hope this helps.

Ok, I have found what causes the problem and I think its a bug.

If you take a radP:RadPanelBar and inside one of the items you place the combo box. If the combo box is not visible when the panel is first rendered, then the drop down button does not function. You can still click in the text area and it works correctly.

Hello Michael Tissington,

Attached, please find another sample project. Everything ran as expected at our side.

I have witnessed that if you have the ShowToggleImage="False" that the toggle image is still visible - it just doesn't work.  I noticed you had that issue in the other thread so I'm just making sure that you haven't set that property on this thread.

[Michael Tissington]

Great idea ... but that is not the problem.
I have found that if the control is not totally initialized correctly then the button does not work. But I'm not getting any errors ...

[Shaun Peet]

What browser are you using?  I'm finding a possible issue when using Firefox, but I'm not sure yet.

[Michael Tissington]

IE 6 and 7 ... to be honest I think this combobox in the features release has several bugs in it and is not reaady for go live yet. I hope their release next week is MUCH more solid.

I have found another issue when doing a item.select(), it selects the item but it does not update the text in the input box.

[Shaun Peet]

It also seems to do some weird things when contained within an UpdatePanel.

Hi there,

First of all, thanks for all your feedback.

The problem about disabling the ShowToggleImage property has been addressed with the latest internal build.

As for the rest of the problems you are facing - I believe that the best way to proceed would be if you send us small and running projects exhibiting the problems. We will test them at our side and try to  solve any problems that appear. Also, step by step details would be of much help.

Nick,

At the moment you do not have a Forums group for this.
And in addition I have been told that formal support is not available for the features release.

[Nikolay]

Hi there,

You are right that the forum threads do not support attachments, however, you could open a new support ticket under the RadComboBox for ASP.NET category. You can simply mention in the content of the ticket that it is about RadComboBox Prometheus.

I too am having the same problem where I can click on the textbox to show the dropdown, but when I click on the button, it does not work. I am using the latest release from yesterday and using all default properties of the control. I have a few comboboxes on the page within an html table - pretty simple. I did notice that there have been a couple times when I display the page, where I can click on the button and it works, but most other times it fails (with no changes to the source).

Hi Brian Doner,

We tried to reproduce the described problem at our side, but to no avail. Could you please reproduce it with our online examples?. Could you tell us which browser you use? Also, we will highly appreciate if you open a ticket and send your page to test locally.

I'm using IE7. I have it working now - it seems that the issue occurs when the combobox is within a div with a height restriction. When I remove the height attribute from the parent div, the comboboxes work properly.

[Rosi]

Hi Brian Doner,

We cannot reproduce the described problem on our side. You can see the attached project for a reference and check what is different on your side.  We will appreciate if you sent us instructions how to reproduce the problem.

I face the same problem also, drop down not working when click on button image.
Another problem i encounter is the data withe & will shown as &amp; in the text area of combo box. (In previous version, it works fine)

I also found out that when we put Prometheous gridview into the page, the radcontrols combobox fail to work.

[Rosi]

Hi ,

Could you please send us a simple running project illustrating the  problems? This will really help us understand the problem better and provide a solution.

Also please see our online example where RadGrid and RadComboBox works as expected together.

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

RadComboBoxImagePosition="Right">

<CollapseAnimation Duration="200" Type="OutQuint" />

<Items>

<telerik:RadComboBoxItem runat="server" Text="Root 1" />

<telerik:RadComboBoxItem runat="server" Text="Root & 2" />

</Items>

<ExpandAnimation Type="OutQuart" />

</telerik:RadComboBox>

Above is the sample code cause drop down text to appear as &amp; instead of &

[Rosi]

Hello cheekl,

Thank you for the provided code.

We will fix this and we will include it  in the next oficial version of the control.

Your points have been updated.

I have tried to use the Rad combo box in a custom web control on a sharepoint page. It renders correctly, but when i click on the button or on the text box, nothing seems to happen! Am I missing any thing?

Please find my code  below:

 

public WebCustomControl1()
        {
            _lbl = new Label();

            Dropdownbox = new RadComboBox();
            Dropdownbox.AutoPostBack = true;
           Dropdownbox.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(Dropdownbox_SelectedIndexChanged);
            Dropdownbox.AllowCustomText = false;
            Dropdownbox.EnableViewState = true;
            Dropdownbox.ShowDropDownOnTextboxClick = true;
            Dropdownbox.ID = "Test";
            Dropdownbox.ShowToggleImage = true;
                  

        }

        void Dropdownbox_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            _lbl.Text = Dropdownbox.SelectedItem.Text;
        }

        protected override void OnInit(EventArgs e)
        {
            Dropdownbox.Items.Add(new RadComboBoxItem("1asdf"));
            Dropdownbox.Items.Add(new RadComboBoxItem("2asdfasdfsadfsdf"));
            Dropdownbox.Items.Add(new RadComboBoxItem("3asdf"));
            Dropdownbox.Items.Add(new RadComboBoxItem("4asdfasdfsadf"));
            Dropdownbox.Items.Add(new RadComboBoxItem("5asdfsadfsadf"));
            Dropdownbox.Items.Add(new RadComboBoxItem("6asdfsadf"));
            Dropdownbox.Items.Add(new RadComboBoxItem("7"));

            this.Controls.Add(Dropdownbox);
            this.Controls.Add(new LiteralControl("Selected Value:"));
            this.Controls.Add(_lbl);
            base.OnInit(e);
        }

Hi Vamshi,

This sounds like there is a problem with loading the Javascript files. You should check if the browser shows any Javascript errors when you open the page.

You can also check the MOSS section of our documentation to see if you are missing some of the necessary steps required to use RadControls in MOSS. This documentation is located at http://www.telerik.com/help/aspnet-ajax/moss-overview.html

Thanks Dimitar,

It was not throwing any javascript error, but got it working now after changing the httpmodules section of the web.config file !!!

Hi, Donot know if this is the rightplace to ask this question and if the issues are related or not but I am facing a similar problem with NavDDL dropdown menu. 

After I navigate to another page using the navDDL dropdown menu which has links, and come back to the page again the dropdown stops working. 

It is also not consistent sometimes it works for 2-3 times and sometimes just stops after 1 redirect. It supposedly works better in IE but tends to fail mostly in Chrome and Edge. Please help me out if you have a clue.
