Greetings,

I have a grid that has only three entries in it with three columns, with 2 visible and the 3rd hidden.  One of my columns is a template that has a label in the Item Template, and a textbox and validator to validate the textbox in the Edit Template.  I have set the grid up to use validation, and I am only doing editing for this grid.  Here is the code for the grid.


Anyways, when I start editing, the validator functions properly.  Then when I try to save what is in the textbox when something is in it, I get this error:

Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate
during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type
and position of the controls added during the initial request.

There are no controls being added or taken off, and for the life of me, I can't figure out what it's talking about.  If someone could help me, I'd be very appreciative.  Thanks.

I have a grid with 2 textboxes.  How can I add a required field validator to the boxes at runtime ?

Hi!

I am use RadCalendar (version 2008.2.826) with MultiViewColumns="6" MultiViewRows="2". But it is work very slow!
How can accelerate work RadCalendar?

Thanks.

I am using a RadPanelBar control to house a hierarchical navigation tree in one of the pages on my site.  The Panel Bar has two or three levels of items, each with an associated ID, parent ID, text attribute, URL and two or three other custom attributes.  I have an OnItemClick event handler to update a section of the page whenever an item is clicked (from a custom attribute named "content").  Thus clicking any item causes a post-back.

My problem is this: although the site runs smoothly on my local server, when I deploy it to a remote server I experience long delays when waiting for the screen to be updated after clicking on an item in the Panel Bar.  Using Firebug to investigate, I have found that a typical page is around 125KB in size, with most of this being taken up by the Panel Bar in terms of HTML tags or ViewState contents.

Is there an optimal way to use the Rad Panel Bar in situations like this when the items are "heavy"?  Can I minimise the amount of ViewState required, or compress it somehow?  Are there any settings that might improve performance?  Or should I be looking at moving a lot of my server-side processing to the client?  Any advice would be helpful, either general or specific.

Thanks,

Ed Graham

Hi,

I have been stuck on an issue for a long time now and in need of some assistance.

I am currently working on a DotNetNuke module with the Telerik DLL which is being referenced. I have Telerik file version: 2008.02.0826.20.

I am trying to make a custom skin for the RadPanel Bar and followed the instructions outlined the Telerik "Basics of Telerik RAD Controls Skinning" and it doesn't seem to work.

The following is the code I am using which is nice and simple.

ASCX:

<

 

telerik:RadPanelBar runat="server" Width="200px" Height="450px" ID="MyMenu"

 

 

Skin="WindowsXP" ExpandMode="FullExpandedItem"

 

 

PersistStateInCookie="False" EnableEmbeddedSkins="false" >

 

 

<CollapseAnimation Type="InBounce" Duration="100"></CollapseAnimation>

 

 

 

<ExpandAnimation Type="None" Duration="100"></ExpandAnimation>

 

</

 

telerik:RadPanelBar>



The structure for the Folders is as follows:

        |__PanelBar
                |__Skins
                        |__PRMS

Hi,
I am using radcontrols with .net1.1 in VS2003. I want to display mastergrid and on clicking a plus sign, a child grid.I have written a simple code for this. But I cannot see the chidgrid on compiling and running the project.I cannot see even the header names of the childgrid. when I click on the '+' sign,it just refreshes the page but show even the headers.
And also I an needdatasource and detaildatabind handlers in the initialize method. But when I use breakpoint to check the flow, the events are not happening. Its just executing FillGridData and nothing else.

Can any one tel me whats happennig?

My user request me to turn off the paging function of the grid, but it turns out the time for the grid to initialize is quite unacceptable(over a minutes). I have read a page about this problem and it suggested to turn off all client side event of the grid, but it is not possible for me as at least the sorting function and row double click event should be kept. So do you have any other method to better the performance? (My target is to show a few hundred record in the grid with no paging)

And I am curious about something. After I use the paging function, and then I change the page side by the "footer bar" of the grid, and it turns out the performance is okay. So why? Thank you.

 I use RadProgressManager and RadProgressArea  with the rad upload control. it works fine in all browsers except safari 3 and above. This happend especially when i try to upload .flp and .cwk  files.

If i upload a .doc or .txt file it works fine.

Please share some light on this.

Does telerik have a gradient, rounded corner panel control, such as this:
