client side:ComboBox: Select item in disabled comboBox

[Taraman]

Hello Telerik,
I have a problem when dealing with RadComboBox.
if the comboBox is disabled, and I want to select an item it doesn't work

the following not working:

ComboBoxTitle.disable();
ComboBoxTitle.findItemByValue("2").select();

the problem is the combo may be disable or not before selecting item so I make the following workaround

if (!ComboBoxTitle.get_enabled()) {
    ComboBoxTitle.enable();
    ComboBoxTitle.findItemByValue(ContactData.TitleId).select();
    ComboBoxTitle.disable();
}
else {
    ComboBoxTitle.findItemByValue(ContactData.TitleId).select();
}

but I am asking if there are a better solution

thanks,
Taraman

Hello Taraman,

When a RadComboBox control is disabled - you are not able to select an item in it.
This behaviour is correct and is by design.
That is why you are on the right way with the approach that you use.

Hi Karina,

May I ask the reason for this design decision?  Why do you not allow an item to be selected in a disabled RadComboBox?  That seems very counter-productive, and I spent several hours today trying to figure out why some JavaScript was not working as expected.

Here is the code from your library which clearly illustrates that the select code is not firing if the ComboBox is disabled...

_select: function (h) {
    if (!this.get_isEnabled() || this.get_isSeparator()) {
        return;
    } var c = this.get_comboBox();
    if (c.raise_selectedIndexChanging(this, h) == true) {
        return;
    } var i = c.get_text();
    var g = c._getLastSeparatorIndex(i);
    var j = i.substring(0, g + 1) + this.get_text();
    var d = c.get_selectedItem();
    if (d) {
        d.set_selected(false);
    } c.set_text(j);
    c.set_originalText(j);
    c.set_value(this.get_value());
    c.set_selectedItem(this);
    c.set_selectedIndex(this.get_index());
    this.set_selected(true);
    this.highlight();
    c.raise_selectedIndexChanged(this, h);
    var f = { Command: "Select", Index: this.get_index() };
    c.postback(f);
}

Thanks for helping me understand.

Happy Holidays!

Hi Thad,

Can you explain the scenario that you want to implement in more details?
Why do you need to set a selected item within a disabled RadComboBox?
Maybe with more details about your implementation we will be able to suggest you a solution?
