    [OPEN] [#38] Combobox with infinite scrolling

    Hi,

    Could you please assist to create a combo with infinite scrolling like it is done with GridPanel in your examples.
    I defined the next store and associate it with a combobox control. As a result: one page only was loaded and the combobox scrollbar was set for this only page. So I can't force to show me items from other pages. Btw I saw 3 server calls for Page #1, Page #2, Page #3. So it seems they were buffered successfully.

    <ext:Store ID="storeObjects" runat="server" Buffered="true" PageSize="100" OnReadData="Store_ReadData">
        <Model>
            <ext:Model runat="server" IDProperty="ID">
                <Fields>
                    <ext:ModelField Name="ID" />
                    <ext:ModelField Name="Name" />
                </Fields>
            </ext:Model>
        </Model>
        <Proxy>
            <ext:PageProxy>
                <Reader>
                    <ext:JsonReader Root="data" />
                </Reader>
            </ext:PageProxy>
        </Proxy>
    </ext:Store>
    Maybe the reason that the combo does not show other pages is he can't deal with Total value which I returned in "Store_ReadData" handler?

    Thanks in advance!

    Hi,

    Unfortunately, it is not supported.

    It is not enough to set Buffered to true. A view should support buffered scrolling.

    At the moment only GridView supports it, a common DataView doesn't support. A BoundList which is used by ComboBox is a subclass of DataView.

    I have asked Mitchell here they are planning or not to support it.

    Maybe, he will answer something concrete.

    For now all that we can suggest is a DropDownField + GridPanel combination.
