[Solved] Reordered event of Listbox issue

I am using the OnReordered event of a listbox to obtain the item index and the item value of an item being dragged and dropped. The item index does correctly represent the place in the list that I dropped an item. If I drag and drop within the same list, everything works as expected. My issue is that when I drag and drop from another listbox, the item value reflected is not the value of the item being dropped, but the value of the last item in the listbox. Is this a bug or is this designed this way? Any ideas for a workaround? Thanks!

Protected Sub listAssigned_Reordered(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadListBoxEventArgs) Handles listAssigned.Reordered

For Each item In e.Items

OrderNode(item.Value, item.Index)

Next

End Sub

ListBox

RadGrid and performance - intended usage?

I just sent this to the support department at Telerik before realizing that it would perhaps be more appropriate to post it here instead. Please forgive the fact that the text is phrased in a way that it was only ment to be read by Telerik personel.

I've been reading about about especially the RadGrid (I am a customer of yours) and have notices you mentioning the awesome performance of the RadGrid which is great. Now I am thinking, how should I as a developer make use of this in the best way, ie, how is it intended to be used. This is of course a question with many answers, but as far as I can see it, the whole idea, unless you have absurd amount of data, or maybe handle very large "blobs", must be that instead of writing stored procedures etc. that does the searching/filtering for you, you should load all the data into the RadGrid, and then let it do it's magic. What I mean is this, if you do a lot of filtering etc. before the data reach the RadGrid, much of the whole advantage with the great performance would be lost, wouldn’t it?

What I am thinking is kind of like this, making stored procedures (or similar) that takes a lot of parameters and does filtering/searching for you isn’t really that difficult, but it takes a lot of time to do, and then you have to make search forms for all these in your web pages on top of that. It would be much quicker if I could just say "Hey, the RadGrid says that it has great performance, and it also offers great filtering capabilities, let's use that instead and save a lot of time!". Is this the intended usage you had in mind when putting in a lot of effort in optimizing the RadGrid performance? Do you have some recommendations, best practices or similar on how to use it, when not to use it etc? Have you done any benchmarking or similar that I as a web developer can use when my DBA comes knocking on the door screaming about that I load all the data from the database?

I hope you understand my questions here, and I know there isn’t an exact answer to this, and that isn’t really what I am looking for, but rather more guidelines on how to use this in a good way!

RadAsyncUpload Control not working in SharePoint

Hi,

We are using the newer version of Telerik. We faced issue with RadAsyncUpload Control on a SharePoint 2007 Site. It is asking for login and does nothing on selection of a file from browse window. It just keeps on loading the content and can see the progressbar rotating continuously.

We are surprised as this was working with Q1 release.

Seems there are lots of issues going on with Q2 version of this control. Can someone help out in identifying a fix for it.

We tried with custom handler and also internal build but nothing comes out.

Need this urgent. Please help.

Thanks,
Nutan

[Solved] Pageindex first

In a RadGrid I use a user control for update and insert:

      <EditFormSettings UserControlName="DetailsDetails.ascx" EditFormType="WebUserControl">
        <EditColumn UniqueName="EditCommandColumn1"></EditColumn>
      </EditFormSettings>

Whenever the "New" is clicked in the radgrid command item template the user control loads find, however the radgrid now displays the last page.

How/where do I set pageindex when the new button is clicked?

Popup Radwinow Disables Parant Page RadComboBox

I am uisng the latest release version of radcontrols in visual studio 2010 in a net4 project.

I have a RCB on my main form inside a rad ajax panel with autopost=true.
When I change the selected index of the radcombobox at the server side it runs the rcb_selectedindexchanged function. Inside this function I call the radajaxpanel.responsescripts.add function to call a javascript routine to open the radwindow.

The rad window winodw pops up fine and i can close the window no problems.

Once the modal window closes though the combobox seems to be in a disabled state (for instance I can no longer drop the list down to select another item).

I have tried setting the radwindow modeless and then trying the combobox before closing the window and I still can no longer use the combobox but I can use other controls on the page?

its as though as soon as the radwindow shows it disables the radcombobox and then does not re-enable it?

Is there anyone there who has seen the behaviour before and could shed some light on how to fix this for me please?
