GridPanel - ComboBox Editor - Show Dropdown When Clicked?

[Tbaseflug]

Currently, I have a GridPanel with a ComboBox editor - the users are "complaining" that they have to click the cell to activate the editor/combobox and then click the combobox to activate the drop down.

Question is - is there a way - that when they click the cell the first time - to now only show the editor/combobox but also pop open the dropdown?

Hi Tbaseflug,

Try adding the following <Focus> Listener to the ComboBox.

Example

<ext:ComboBox ID="ComboBox1" runat="server">
    <Listeners>
        <Focus Scope="this" Handler="el.onTriggerClick();" Buffer="50" />
    </Listeners>
</ext:ComboBox>

You just need the <Listeners> section, the rest will remain as you have it already configured.

If it fails, try bumping up the Buffer value by +50 to a max of 200.

Actually, that worked great! Thanks!!!!!!

Out of interests sake, could you confirm if the following simplified <Focus> Listener works as well.

Example

<ext:ComboBox ID="ComboBox1" runat="server">
    <Listeners>
        <Focus Handler="el.expand();" />
    </Listeners>
</ext:ComboBox>

Actually, I tried that this morning - but just put it in again and get:

Ok. Thanks for the update.*

I guess it's best to use the onTriggerClick solution.


For the v1.0 final release, we'll try to figure out why the el.expand() Handler does not work and hopefully implement a fix.*

Thanks!

I am experiencing this as well. Is there a way to have a combobox appear in the GridPanel with having to click on the cell first?

Thanks.

mrbiglzwerth,

Did you ever find a solution that allowed you to show the combobox without first clicking the row/cell?

[mrbiglzwerth]

No unfortunately I did not.
