Fixes for Load on demand are not working correctly when enabling ShowMoreResultsBox property.

[Aviii]

HI,
Thanks for this load on demand fixes from the following link. 
http://www.telerik.com/community/forums/aspnet-ajax/combobox/fix-load-on-demand-does-not-work-correctly-in-q2-2009-sp1.aspx

I added following code of block below scrpt manager.

<script type="text/javascript">
    Telerik.Web.UI.RadComboBox.prototype.get_endOfItems = function() { return false; };
</script>

I was able to get results after pressing more than one character. But this solution raised me another issue.

I Used Property ShowMoreResultsBox="true" in combo box because I have about 16000 reocords in Combo Box, and I display 500 records on a page. The Button to get next 500 records works fine till i dont type any character and when I press two or more characters the my webservice return 2000 records, and I display 500 but I am not able to get Next 500 records, becuase the button does not clickable ot just return false; (I guess becuase of this fix).
The issue is on production and We dont want to update with new Telerik dlls.
Please help me to fix this issue.

Thanks
Aviii

Hello Aviii,

You can try resolving this (without updating the dll) by replacing the fix suggested in the forum sticky with this one:

var requestItems = Telerik.Web.UI.RadComboBox.prototype.requestItems;
Telerik.Web.UI.RadComboBox.prototype.requestItems = function (text, appendItems) {
    if (appendItems && this.get_endOfItems())
        return;
    this.set_endOfItems(false);
    requestItems.apply(this, arguments);
};

Please let me know how it goes on your side after applying this fix.

Kind regards,

Hi Simon,

Thanks for posting this fix. For now I am stuck with version Q2 2009 SP1 and your workaround works for me (at least after a few tests). Hopefully it will hold up in production too.

Thanks,
Oran

Hello Tyler,

It should cover 99% of the cases, so using in production should be OK. However, just to confirm, it is a good idea to test your use-cases just to be sure before putting it in production.
