X - How to save list checked items?

[The GridLock]

Hi,

I don't want to use the ok button, can I click and after I leave the mouse away from the combobox, then the combobox will keep the list I have selected and display list concat string in combobox.text ? (it didn't save this !)

Also, can I checked all items by code?

Thanks!

Hi GridLock,

Query 1: When click away from SfComboBox need to update the checked items

You can achieve your requirement by hiding the Ok and Cancel button with help of SfComboBox.DropDownControl.ShowButtons bool property.

please refer the below video for your reference.

Query 2: How to check all items by code

You can achieve your requirement by adding the dropdown items into SfComboBox.DropDownListView.CheckedItems collection. Please refer the below code snippet.

private void Form1_Load(object sender, EventArgs e) 

{ 

    foreach (var v in this.sfComboBox1.DropDownListView.View.Items.ToList()) 

    { 

 

        this.sfComboBox1.DropDownListView.CheckedItems.Add(v); 

    } 

}

Hi Durai,

query1 doesn't work for me.

Edit: It seems that an event has prevented me, or I need to focus on a certain location for it to work.

Can I use some event to do it? I was thinking of using dropdownclosing to save list then reassign this list by event dropdownclosed, but not sure if it works.

query2, I hope sfcombobox.selectall function will be available soon :))

Hi GridLock,

Query: When click away from SfComboBox need to update the checked items

We have analyzed the reported query; you can achieve this requirement, only after closing the dropdown and can't focus the certain location(DropDown) with help of event.

after:

how can i avoid this?

Hi GridLock,

Thanks for your update.

This is default behaviour of SfComboBox, so you can't restrict and change the text fore color when SfComboBox.Enable as false.

Hi Durai,

agree! I thought that watermark is a label that works independently of combobox but it seems to be a given text and color. So I used text instead of it :))
