Hi everyone, is there any way to have a ComboBox with SearchBar just like the on i uploaded?

The search bar will search for what you typed according to what you have in your items of the combobox.

Thanks everyone!

    You helped a lot, it solved my problem and it’s working perfectly fine, thanks kevin!

    You could implement this as a usercontrol in future WiseJ versions, it’s so good.

My take on this would be to set AutoCompleteMode to AppendFilter and add a InitScript to have the filtering.

Thanks Kizaemon,

with your detailed description I could reproduce it.
We´ll fix that issue and I´ll let you know when it passed QA and is included in a next Wisej.NET release.

Hi Kizaemon,

thanks for following up on this.
I have tried your test case with our latest internal build and could not reproduce it.

Can you please tell me which Wisej version you are using that shows the issue you described?

Thanks in advance!

Best regards
Frank

    Hi Frank, the Wisej version is 3.1.2 with dotnet version 4.8.03761. I added a screen recording (webm in zip) to demonstrate the steps. 1) Bind collection A (with 3 items) 2) Select the third item (Antigua) 3) Bind collection B (with 2 items) 4) Select the first item (Zambia)

Hi Kevin,

 

thank you for the example of UserComboBox usage.

It is working well if the CB is filled using both Items.Add method and DataSource property.

 

When re-binding the CB to a different list, the Items.Clear/Add methods are working well.

But the WiseJ Framework throws an exception when re-binding to a different collection using the DataSource property, containing less elements that the previous one.

 

I attached a sample project to reproduce.

Steps to reproduce:

  1. Bind using the DataSource property to a collection with 3 elements.
  2. Re-bind  using the DataSource property to a collection with 2 elements.
  3. Try to select from the list
  4. Index-out-of range exception is thrown.

    Hi Kevin, answering my own question. As a crude work-around, setting the DataSource to null and SelectedIndex to -1 before binding to a new DataSource seem to suppress the crash. public override object DataSource { get { return base.DataSource; } set { if (base.DataSource != value) { base.DataSource = null; base.SelectedIndex = -1; base.DataSource = value; } } }

Hi Ruben

For the moment this feature isn’t available

Wisej.Net support the filter mode in AutoCompleteMode.

The search bar is different.
Development team is actually been working on it and be available soon

As workaround for now it can be implemented using a UserComboBox
and panel in the drop down with textbox and listbox, etc.

Regards

  • ruben ribeiro
    And how do i give a TEXT to the usercombobox1 as soon as i select something?
  • ruben ribeiro
    example i select a label with the text: “Y” and i want to usercombobox to close and shows “Y” in the usercombobox . just like a combobox when u select smth u can still see what u selected.
  • ruben ribeiro
    Also i cant add controls to tuse usercombobox idk why, im tryind: Dim x as new label …. .. usercombobox1.items.add(label) even buttons its not working
  • Luca (ITG)
    You don’t need to add controls, just assign the drop down control. In there you can place whatever you like. It’s a “User”ComboBox, the implementation is up to you.

    Sorry sir, could you please send me code example or source example?
