All Im trying to do is pass a default value to the bound EDICustomerID feild so that when a new code is created via the radgrids 'add new record' it gets the value from the querystring Which holds the EDICustomerID that all codes belong to. 
What is the cleanest / best practice way to get the default value to be a value from the querystring?

I tried the following but while it didn't throw an error, it didn't work, either:
ASPX:

objectDataSource(c#):

And finally the object its self:

I have a screen where I have a treeview that loads 

 foreach (var user in allUsers)
            {
                var claims = db.AspNetUserClaims.Where(c => c.User_Id == user.Id);
                foreach (var claim in claims)
                {
                    if (claim.ClaimType == ClaimTypes.Role)
                    {
                        for (int i = 0; i < UserTree.Nodes.Count; i++)
                            if (claim.ClaimValue == UserTree.Nodes[i].Text)
                            {
                                var userNode = new RadTreeNode(user.UserName, user.Id);
                                UserTree.Nodes[i].Nodes.Add(userNode);
                            }
                    }
                }
            }

This loads fine when I click  + for the parent it expands to show the children.  This all works the issue is on the NodeClick event.  The very first time I click on a node it reloads the page and never runs the NodeClick Event.  After this one time event everything works properly.  I can expand and contract nodes and when I click on a node it rune the node click properly.  It is just the initial node click after the page loads that has this behavior.

Hi Gurus,

  I am dynamically calling a usercontrol,

  my issue is,when i click the paging button,the control is not loading (i need to use custom paging not built in paging)

Here is the code:

I need it urgent,how to accomplish this,is any possibilities by using Delegates or any wayz,if so how to do that.

Help me with this.



Thanks in Advance

Hello, the bug is very easy to reproduce. This is the 4th bug I've found with decorator in one month after start using it with Lightmode rendermode, evidently it is flimsy and needs testing.

.aspx



.cs

I am begging for some kind soul to help me here.

I have tried everything I can think of, and I haven't been able to fix this problem.

For some reason, some appointments appear perfectly fine on my Scheduler, and others get cutoff. The code is exactly the same for both appointment creations.

Note: I am creating appointment manually and using the InsertAppointment() method to add them to the Scheduler.

I thought that maybe it was affecting only appointments scheduled in the future from the current date...but when I moved appointments around, I found (as you will see in the attached image) that I was able to see appointment perfectly from the 5th (current date) to the 9th. But starting the 10th, it gets cutoff. It's so BIZARRE...

PLEASE PLEASE Can anyone help me fix this?

I have setup the RadAjaxPanel.RequestQueueSize property so that if the user clicks multiple widgets on the screen the actions will be queued. Previously I had the value set to 0 and we would get intermittent viewstate errors as cancelling the previous request somehow mangles the viewstate on the next request. With the RequestQueueSize property set > 0 I am seeing some very strange behavior where the last queued action seems to fire twice. I have no idea why this is happening or how to prevent it. And advice/information on the subject would be much appreciated. Thanks.
