I have a datalist with custom paging thats inside a RADAjaxPanel in a usercontrol.  When I select pages in Firefox, the ajax functionality works fine (there is no full page postback), however, the same page in IE8 & Chrome generates a full page postback.  Anyone know why this should be ?  are there extra steps to take when using IE & Chrome ?

Hello,

Using the RadMenu client-side API (http://demos.telerik.com/aspnet-ajax/menu/examples/programming/clientsideapi/defaultcs.aspx) is it possible to open a RadMenuItem when a page loads?

Thanks,

Matt

Hello,

I created a RadToolBar with version Q2 2008 and everything look great. I'm now upgrading our site to use version Q3 2010, and my RadToolBar now looks ugly. There are three main faults. (See attached screen shots)
1. A white bar has appeared when a button or drop down menu is highlighted.
2. Buttons that belong to a drop down do not show there images fully.
3. Buttons that belong to a drop down are highlighted in bars.

I've created a test site with a RadToolBar. I can change my reference of Telerik.Web.UI.dll from Q2 2008 to Q3 2010 to experience the differences quickly, which looks like:

 

Can anyone help me to fix these faults?

 

Thanks,

Matt

Hi all,

I have been using Telerik's tutorials on how to dynamically add docks to a dock zone. Inside of my dock is a chart which has drill-down capability. I do not seem to be doing something correctly, however. When the user interacts with the chart (it seems) that some of the dock's initially set properties are being forgotten.

Image: http://i.imgur.com/3Qrqn.png

The upper image is a freshly created dock zone. The second image is moments after the user clicked a series on the chart and 'drilled down.' I placed breakpoints throughout my code and it seems that the upper bar is disappearing before Page_Init is called.

In addition, if the user refreshes the page or grabs the dock and drags it, then allows it to drop back onto the dock zone, it resets to its initial state. The title bar becomes present again.

Here is the relevant code I have written:





RadDockLayout1_SaveDockLayout, LoadDockLayout, CurrentDockStates, CreateRadDockFromState are identical to those given in your examples. I believe the above should all be mostly identical, if not identical, as well. 

The only difference I can see between my example and http://demos.telerik.com/aspnet-ajax/dock/examples/myportal/defaultcs.aspx is that my example does not use a 2nd UpdatePanel. Instead, I am using the RadAjaxManager to refresh the view after a user has drag/dropped/created a dock. 

Does this seem correct? Can I provide more information?

Sean

EDIT: I see why the state of the graph reverts to its top level view. During page_init all the docks call LoadContent again to, in theory, reload the content they were displaying before. In practice, a user has navigated one level deep into the chart and then LoadContent is called -- this retrieves the top level of the chart, not one level deep. Any advice on how to handle this scenario would be much appreciated -- I do not see a great way of handling this.

If I have created a multicolumn radcombobox, how do I access the secondary selected column values in the code behind?  I can't locate an example of this.

Thanks,

Hi,

I have a radGrid to which I add GridHyperlinkColumn at runtime. I need to pass Navigation urls to these which depends on the values of the other cells.

GridHyperLinkColumn column = (GridHyperLinkColumn)gridBoundColumns[j];
column.DataTextField = gridField.DataField;
column.HeaderText = gridField.HeaderText;
column.NavigateUrl = "accountview.aspx?id=<%# Eval(\"AccountID\") %>";

If I pass the NavigateUrl value as above it is taking as a string but not replacing Eval("AccountID") to the value in that cell.
How to achieve this functionality like this???

Thanks,
Mahesh

Hi,

I have a web application with multiple user controls. Each user control has a radgrid and gets loaded on-click of respective image buttons. For a certain user control, on-click of the image button, I call an async ajax jQuery pagemethod to populate a container class which I use later. So, on-click of the image button, the user control gets loaded and the pagemethod gets called. Now, the radgrid for that user control has virtual scrolling and when scrolled, it sends ajax request with AjaxRequestWithTarget. The issue is that, the earlier pagemethod call is blocking the ajax request. The ajax request is getting blocked till the time the async ajax  pagemethod completes its task.
Is there any way to overcome this issue ? I expect the ajax pagemethod to be async and shouldn't interfere with any other calls/requests and should run in the background.
Any help is appreciated.

Thanks!

I'm using the Advanced Form.  No problems with it.  Everything works fine.  Except...when the form comes up, only the controls and text load, and the form itself is actually clear (you can't see it).  What could I be doing wrong?  I can even click and drag the form around.  Please see attached screenshot.

It was actually working fine earlier.  The first time I saw this was when I uploaded it to the production server.  And then after I upgraded the project to the latest version, it started doing it locally too.

Hi,

I'm messing around with creating a dock page which has several selectable controls which you can add to a single dock. I got this working fine with session objects, but am struggling trying to move it to use cookies. Could you help?

The problem seems to be that it looses the controls from the dock after the postback. In the example I was using with sessions, there was some code in the page_load which recreated the docks, I'm not really sure how to do this from the information that is stored in the cookie. Should I be looking at serializing the dockstate dictionary, or recreating the docks from the cookie information? Heres the code I've got:

Thanks for any suggestions,
Lee.

It also uses a master page and a web user control, but these have nothing in them except some html to test with.

Hi,

I have upgraded the RadEditor to the latest Telerik.Web.UI version and used the ToolsFile.xml to generate the toolbuttons.
The button IncreaseSize,DecreaseSize,ToggleDocking,RepeatLastCommand onclick give the message that it is not implemented.

Please suggest how to solve this.

Thanks In Advance.
