UserComboBox hides setted dropdowncontrol

Hi Eric,

thanks, it´s a regression between dev builds. We have fixed it and it will be included in the next Wisej release.

We´ll inform you when it´s online.

Best regards
Frank

Hello,

Is it me or the latest Dev Build version 1.4.54 has broken the usercombobox ??

I should be able to create a UserControl, Build, Add it to the Window at design time, add a userComboBox and set it’s DropDownControl as the userComboBox.

• At first time run, the user control is visible and shown where placed on the window, but not shown when clicking.
• At second run the user control has disappeared, but still not shown when Clicking.

I’m missing something ?

As work around (but then what’s the meaning of having a usercombobox instead of combobox):

    public partial class Page1 : Page
{
public Page1()
{
InitializeComponent();
userControl1.Location = new System.Drawing.Point(userComboBox1.Location.X, userComboBox1.Location.Y + userComboBox1.Height);
}

private void userComboBox1_DropDown(object sender, EventArgs e)
{
userControl1.Visible = true;
}

private void userComboBox1_DropDownClosed(object sender, EventArgs e)
{
userControl1.Visible = false;
}
}

Regards.

Thank you. Got the sample.

The custom drop down works well when you don’t use a UserPopup inside the dropdown. Which is correct. The user popup is meant to be used programmatically this.userPoup1.ShowPopup() to show a popup panel in relation to a control.

There is a bug when displaying a context menu in a popup, it seems that when the popup is closed, the context menu is reopened at 0,0. Will log and get it fixed in the next update hopefully.

For the ComboBox in the drop down, I cannot reproduce. I get the data in the drop down. There is a sample I linked before with a complex drop down including datagrids with data. Can you attach a test case showing the other issue you mentioned?

I created a small project with the same results.

Can you attach the test case?

This is the second sample. 🙂

Hi Luca,

As you said when I use panel it works perfect. I will use that. But I found another bug I think. Take a look at my animated gif attachmet. When I am using userpopup problem is still alive. I will attach animated gif screen cast in second message.

Thank you.

I can’t reproduce. Try the app attached here: https://wisej.com/support/question/initial-test-on-usercombobox

If you are using a UserPopup as the control attached to the DropDownContol property that is probably the issue. The DropDown part is already a UserPopup. You can use any control, including  panels.

Hi,

thank you for fast fixing. 🙂

I think I found another one. This time, similar problem is seen at runtime.

At first click to usercombobox shows what I need (userpopup) and It seems work perfect. But after second click, it shows nothing.

I am working on the version 1.3.42.0.

thank you.

From the image looks like you are using a UserPopup for the UserComboBox. The UserPopup is supposed to be used independently from the UserComboBox, it’s a panel that you can popup programmatically in relation to any other control. The UserComboBox already uses a UserPopup as the drop down.

However, there are 2 bugs: 1) the control assigned at design time is removed from the design surface  – it should be removed only at creation; 2) when detaching the control from the DropDownControl property, the parent is not restored. Logged as WJ-8087 and WJ-8088.
