Hi, my boss just upgraded from 2008.1.515.35 to the 2009.1.402.35 version of the Telerik ASP.Net AJAX controls (I believe from Q3 2008 to Q1 2009) and now I'm getting the following two problems...

Problem 1

Telerik.Web.UI.GridFilterMenu with ID='rfltMenu' was unable to find embedded skin with name 'ourcustomskin'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

It looks like the rfltMenu is auto generated by the control, as I can't find it.  I rolled things back to the older version of the control and everything works fine.  Did the underlying skin structure change slightly?  Anybody seen this before?  I'm being lazy here, if I dig hard enough I bet I can fix this, but if someone has a quick fix I'm all ears.  Problem two is a little more challenging.

Problem 2

We have a custom implimentation of the templategridcolumn that is stackable (i.e. you can have multiple data items per row).  Usually we stack two data items per custom template column.  Again, with the new version of the controls, filtering no longer works where before it did (could be related to problem 1).  It looks like the Javascript generated by the Telerik will no longer fire the filter event if the first filter column textbox is empty in the column.  In most scenarios that would be fine, but since we have two or more filter texboxes (one per data item in the row) you could be filtering off the second textbox while leaving the first filter text box blank.  Anyone have problems like this?  Is there a decent example of over-riding the default javascript filtering behavior so we can pull this off?

I think I will hold off posting source code for now, probably have to open a ticket.  But if anyone has encountered these issues any help you can offer would be helpful. Thanks.

Hi all,

I have a pretty large RadGrid with a lot of columns. I'd like to have a column picker outside the grid itself, so that I can show that to the visitor in a more structured way. I know I can enable a ContextMenu for the Grid, but that is not the way I want the user to interact, since it is not that nice (a really long  list with checkboxes).

How can I bind e.g. a CheckboxList or some other control to the available columns on the Grid and hide or show them?

Best,
Daniel

I consider using Telerik SP 2013 web parts in my environment to produce reacher GUI for end users.
I have a lot of BIG document libraries (thousands and tens of thousands of documents).
There is a throttling mechanism in SP 2013 which causes problems in using standard SP views when working with big document libraries.
One of proposed solutions is building views based on search capabilities of SharePoint instead of just querying list data.
I would like to know if Telerik web parts are based on regular data querying (just like regular SP list views) or on SharePoint search.

Thank you very much, Masha.

Hello,

I would like to implement some kind of lazy loading in RadGrid.

Let's say we have page with collapsed panels (via jQuery) in page. Every panel contains server generated user control - mostly grids. Current behavior is that when page loads, all grids loads data and renders everything. We need to collapse all panels and force grids to set data sources on server side (as in current state), but do NOT databind.

We want to implement calling databind() from javascript when client expands panel.

I found on web that only way how to force grid not to databind is set visible=false; But I don't think this is the best way, because control is not rendered and there is no way how to set visibility from javascript and call databind, or not?

Is there any way how to do it? Some kind of disable auto databind?

Regards
René

Good evening,

I'm working with the ASP.NET GridView as well as the Telerik RadGrid and I'm missing a behavior on your Grid that was kinda typically on the classic Grid of MS.

Let's say I'm displaying 100 items per page of 1000 items total, paging is on and I am on page 3. On the MS grid I'm able to limit the bound data to the data I just want to display, and I still can trick the Grid to believe there are more items than actually bound by setting VirtualItemCount to 1000 to still get my 10 pages on the navigation instead of just one. So I only have to load 100 sets of data from the database for every postback. When sorting the data, I can simply order the data before skipping and taking and finally binding to my data, such as on the entity framework.

Your grid is awesome, because it tries to do the order-job for me. But this only works if I give your grid the full 1000 items on the data source, I dislike. 
But first, I tried to simply display 100 items and set VirtualItemCount to 1000. The page navigation was not shown, assuming it was only 1 page for it.

Can you provide me any way to tell your grid to act like there are 1000 items on it, while only 100 items are bound? When this would work, I know the grid cannot sort all my datasets when the user presses on a column of course, because the grid has not all the data. Can I implement the manual sorting to your grid on similar ways like on the ASP.NET GridView?

An minimal example just with the features I'm looking for would be great.


Thanks in advice.

I have a form with a RadButton set to use the new SingleClick and a RadDatePicker with a RequiredFieldValidator.

The button stays depressed after clicking if the  RadDatePicker is empty.

Any ideas?

Hello. With some help, we recently added the ability to scroll to our bar charts by adding a blank line series. After doing so, I noticed that the tooltips no longer appear when hovering over the bars in the bar chart. To make sure everything was working properly, I turned off scrolling and the tooltips appeared as they should.

Is this a bug, or are additional steps needed to make this work?

We're using the latest ASP.Net Ajax controls.

Thanks! Please let me know if I can provide any more details.

I am tring to save information based on if they pick a date back inot the Db.  So I am checking on the selectedvalue of the raddatepicker but it gives me this error when I do not have a date in there.

Bassically what I want to do is rotate through my radgrid and if they have picked a date then save information to the DB otherwise just go to the next row.  But this error pops if no date is picked.

Nullable object must have a value.

Line 238:            If TempDt.SelectedDate.Value > Nothing Then
