DropDownStyle = DropDownList still shows cursor?

[Johan]

Hello,

I want to use a non-editable combo box in my user interface. Setting DropDownStyle to DropDownList almost does this for me except that I can still see a edit cursor when I press the mousebutton inside the combobox. Is there any way to get a win-control behaviour where there never is any edit cursor?

Hello Johan,

We are investigating the issue, but at the moment we are unable to find a general and stable solution that works out of the box in all cases. What we can suggest is that you try your own custom logic using the following Win API:

HideCaret - http://msdn.microsoft.com/en-us/library/ms648403(VS.85).aspx

and

ShowCaret - http://msdn.microsoft.com/en-us/library/ms648406(VS.85).aspx


Sincerely yours,

Hello Telerik team,

In my opinion "ordinary" cursorless DropDownLists are a frequent requirement in software applications.

Our UI needs dozens of those comboboxes. But the Telerik Combox looks a bit confusing. The user gets a cursor but cannot edit the value. We're not very happy with that at the moment and think about falling back to the old fashioned Windows Forms combobox.

Are there concrete plans to enhance the Telerik Combobox to support "ordinary" DropDownList behavior in the next release? We'd need it desperately ;).

Cheers,
STB

Hi Stefan Berkmiller,

Thank you for the feedback.

We have initiated an extensive research to find how we differ from the standard controls so that we can address all inconsistencies. We realize that although our controls cover nearly 100% of the functionality the standard controls offer, there are still some differences we need to work out. The current case is one of them.

We will consider improving the current behavior, because it is indeed misleading. Hopefully you will see the improvements as soon as Q1 2009.

Do not hesitate to write me back if you have more questions.

Hello,

I have also run into the same problem. I've tried the using the "HideCaret" function from user32.dll, but still no luck.

Has there been any progress in the arena?

Thanks,
Tim

 Hello Tim, guys,

To our regret, our aggressive schedule for Q1 2009 did not permit us to address this issue. I have raised the priority of this, as the interest in this bug fix seems to be picking up.

We are moving towards Q2 2009, and we will try to include this functionality there.
 

Best wishes,

Any more on this "feature?" I coudn't agree more with the comments in this thread. It is beyond confusing and might be better described as appearsing broken. This control, or state, is probably one of the most commonly used controls in an application and we as well might not adoopt the toolset if we can't get basic standards implemented. 

Any hacks workarounds in the meantime are welcome.

Thanks,

Hello Troy,

Thank you for the feedback. I have raised the priority of the RadComboBox issue when it is in DropDownList mode.

Until the issue is addessed, please consider using the following code snippet:

[DllImport("User32.dll")]
static extern Boolean HideCaret(System.IntPtr hWnd);

public Form1()
{
    InitializeComponent();

    ((HostedTextBoxBase)this.radComboBox1.ComboBoxElement.TextBoxElement.TextBoxItem.HostedControl).MouseEnter +=new EventHandler(Form1_MouseEnter);
    this.radComboBox1.GotFocus += new EventHandler(radComboBox1_GotFocus);
}

void Form1_MouseEnter(object sender, EventArgs e)
{
    ((TextBox)this.radComboBox1.ComboBoxElement.TextBoxElement.TextBoxItem.HostedControl).Cursor = Cursors.Arrow;
}

void radComboBox1_GotFocus(object sender, EventArgs e)
{
    HideCaret(((TextBox)this.radComboBox1.ComboBoxElement.TextBoxElement.TextBoxItem.HostedControl).Handle);
}

As you can see, I am hinding the caret of the TextBox that RadComboBox hosts and I am changing the mouse cursor to a normal arrow when the mouse pointer is over the hosted TextBox.

I hope this helps. If you have additional questions, feel free to contact me.

Kind regards,
Nikolay

Telerik,

Is there a recent update for this issue? This item was originally slated for Q1 2009 (it was first mentioned in 2008). The suggested "solution" which uses HideCaret() is not acceptable.

Thanks,

Any word on this one yet?  This is needed in MultiColumnComboBox as well

[Nikolay]

Hello michael mccurrey,

There is no cursor in RadMultiColumnComboBox when DropDownStyle = DropDownList in Q1 2010. I would recommend you to update to this latest version if you have not done it so far. If you have additional questions, feel free to contact me.
