Hi,

 

Can you try this approach for now?!:

 

UniComboBox -> ClientEvents -> ExtEvents -> function beforerender:

function beforerender(sender, eOpts)
{
    sender.defaultListConfig.maxHeight = 50;
}

Best regards.

[jahlxx]

Ok.

 

Thanks.

Hi.

 

I have 2 more questions about unicombobox:

 

1. How can give a custom witwd when the combo is displayed?

 

2. When I set a value tothe text property, in run  time, the combo value is not refreshed. How can I do?

 

Thanks.

Hi,

Custom width ?!

 

 

2. When I set a value tothe text property, in run  time, the combo value is not refreshed. How can I do?

 

Make a testcase, how do you do that ?

[Sherzod]

Custom width ?!

 

If yes, then you can try this approach:

 

UniComboBox -> :

 

1. MatchFieldWidth -> False

 

2. function beforeInit:

function beforeInit(sender, config)
{
    sender.defaultListConfig.width = 300;
}

Ok.

 

Works. But I think could be better as a property of yhe unicombobox. Is only an idea.

 

About the 2nd. question, just take the combotrig demo, and do these changes:

 

in combo's items put this:

 

A - letter a
B - letter b
C - letter c
D - letter d
E - letter e
 

 

And in the mainform onshow event, this line:

 

unicombobox1.text := 'D';
 

I think that because D match an item of the combox, the text should be updated automatically to "D - letter d"

I think that because D match an item of the combox, the text should be updated automatically to "D - letter d"

 

How it works in the VCL, have you checked ?!

How it works in the VCL, have you checked ?!

 

You can try it with this config:

function beforeInit(sender, config)
{
    config.typeAhead=true;
}

[jahlxx]

Almost.

 

The text property are updated when match any value, but does nothing when assign a value directly.

[jahlxx]

Ok.

 

I've workarounded this.

 

Other question about this.

 

Has unicombobox has equivalent to selectall procedure?

 

Thanks.
