RadCheckedDropDownList focusing popups?

[Jeff]

Hello ,

I am trying to use a radCheckedDropDown list in a winforms application (C#).  The list is working the way I want it to except for 1 thing.

When I click the dropdown list it shows (which is correct) however while it is open if I start to type in the text area the text popup shows in front of the dropdown popup, and as a result you can click through to the drop down list.  What I would like is to close the dropdown portion when typing, and vice versa when using the drop down list. 

If I use a standard combobox I can accomplish this by  hooking the preview and the droppeddown events, however the radcheckeddropdownlist does not have the droppeddown event.

private void comboBox_DropDown(object sender, EventArgs e)

{

ComboBox cbo = (ComboBox)sender; cbo.PreviewKeyDown += new PreviewKeyDownEventHandler(comboBox_PreviewKeyDown);  

}

private void comboBox_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)

{

ComboBox cbo = (ComboBox)sender;

cbo.PreviewKeyDown -= comboBox_PreviewKeyDown;

if (cbo.DroppedDown) cbo.Focus();

}

 

Thanks,

Jeff

Hello Jeff,

Thank you for writing.

You can use the AutoCompleteTextBox TextChanged event and close the popup. You can subscribe the event like this:

radCheckedDropDownList1.CheckedDropDownListElement.AutoCompleteEditableAreaElement.AutoCompleteTextBox.TextChanged+=TextBoxItem_TextChanged;

If the autocomplete drop-down is shown and the drop-down button is clicked the items drop-down will be shown and the autocomplete drop-down will be automatically closed.

Please do not hesitate to contact us with any additional questions or concerns.

Hello There,

 

I am  running into an odd issue with this checked box.

 

I have attached a sample piece of code (64 bit) to demonstrate the issue.  What I want is the functionality of the combobox when I type. If I open the dropdown and then start using the textbox portion with the added part for the combobox I have it so it closes the drop down.   Where as with the checked dropdown it is not the case.

 

Also I have noticed when using a datasource sometimes the popup shows for the checked dropdown and other times(lists) it does not and I can't see any difference in the settings of the checked dropdown.

I just saw no zips allowed. 

Here is quick screen shot.

Both dropdowns are set to suggest and append for the autocomplete and set to list.

The screenshots failed to attach.

Nevermind.

 

I solved the issue..  It had to do with the minimum popup size being set to 0,0.
