Disable Scrolling if Not enough items to Scroll Through

Hello,

How can I disable the scrolling if I don't have enough items to scroll through? For example my rotator is high enough to display 3 items, and I want to disable the scrolling (nothing should happen when user tries to scroll) if there are 3 or less items in rotator. I still want Buttons to be displayed though.

Thank you,

Rotator

[Solved] Bug in Editor version 2009 Q2 and Q3 in IE8

Hi,

I found a bug in the recent versions of the Editor control with Internet Explorer 8. You can reproduce the bug at the Demo site of Telerik. Just go to the Editor Demo - First Look (http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx) and set the ToolbarMode to ShowOfFocus. Then click the Toggle Fullscreen button on the toolbar to go to fullscreen mode and click the Toggle Fullscreen button again to go back to default mode.
At this moment the content area does not have the full height again. I have tested it in IE8 and Firefox. This problem only occurs in IE8. IE8 with IE7 compatibility mode set, the problem does not occur!

Please confirm this bug and I hope you guys can find a workaround for this problem?

Thanks,
Danny

CustomPaging with Filter

Hi,

I have a table with over million records so that the query in LINQ is so slow.
Originally, my code in NeedDataSource event was

var query = (from prod in dldc.Products

select prod);

and I set

AllowPaging

="true"

AllowCustomPaging

="true"

AllowSorting

="True"

AllowMultiColumnSorting

="True"

and assign the result to RagGird.DataSource. Actually here is a quick sample, the result is not only from Products, it needs to join other tables, a lot of tables.
Then I got the the performance issue, it took me over 20 mins to show the results. So I am going to use CustomPaing to make the it easy and I put the below segment in NeedDataSource event:

var

query = (from prod in dldc.Products

select prod);

query.Skip(page * size).Take(size);

Anyway, the grid looks fine by using such paging instead of query all records from database. However, the filtering only filter the result over current page that is not what I exactly need.
What I need is to boost the performance up with both paging and filtering. Also, how do I make RagGrid filter the products over all the products, and also with paging?

Thanks in advance.

InvalidCastException during filter operation

Hi all

I have just added a filter to a grid (a list of wines with name, vintage etc).

When I attempt to filter on Vintage I get an InvalidCastException which seems to be
caused by a Null value for Vintage in one of the records in the database.

How can I allow this filter to work even when there are some null values for
that column?

Thanks for your help!

Grid Expand + Buttons

Hi

I'm pretty new to RadGrid so take it easy on me please.

I'd like to use the expand functionality to show buttons on the expanded line rather than any hierarchical data sourced from the expanded line, is it possible to just have a single line with a number of buttons appear when the expand is clicked? Obviously I'd need to catch the click event of these buttons also.

Thanks in advance.

Chris.

[Solved] Spell check Server Error 500

Hi,

I'm using the spellchecker on a form and am checking 3 textboxes. It works OK on the development PC but on the server when running live the spellchecker window appears but I then get a standard IE alert window detailing a Server Error 500. Exception details as below:

Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.

Has anyone encountered this one before or could point me in the right direction?

Regards,
