I am building up the grid dynamically based on metadata. When I started building the grid, the sorting and grouping worked. Then after some time I found out that it is not working anymore. When I click on the column header, the SortCommand event is not raised. I checked that the AllowSorting property is set to true.

I tried to find out what caused the sorting to stop working, but cannot find it. What could cause this?

PS I use the __EVENTARGS in a postback to indicate what action the user wants to be performed. Do you use that too?

Hello,

I have created a composite control with the RadDatePicker and 2 CompareValidators and 1 CustomValidator.  When I try to attach the RadDatePicker to a RequiredFieldValidator from the calling page i am getting the Error

I am sure I am missing something simple here.

I have created a function to call a storeproc and want to return the results to a listbox:


If I use a radgrid the grid populates correctly but if I use a listbox the funtion only returns system.data.datarowview.

Can some one please set me straight.

Thank you.

How can i graph 2 different series against the samy y-axis. I have been able to successfully do 2 series, on the y-axis and secondary y-axis, but now I'd like to have them scaled on the same y-axis.

When I make a change to the schedule, or if I view the AdvancedEditForm for a particular appointment, I start getting the following error when I hover over an appointment:

Unable to get value of the property 'get_allowDelete': object is null or undefined

If I add a new appointment the page refreshes (via Ajax, not a full postback).  I can hover over the new appointment without a problem, but any existing appointments will throw this error.

When I step through the JavaScript debugger, I see that there is a call to get_element(), and this method looks in the first position of the _domElements array.  In my case, the first entry is null, but the second contains the element that it should be returning.

Hi telerik ppl:

Im using this code to swap languages for the column headers and also for the grouping fields labels within the group panel.
 

 
The problem here is that the objects within the Group Panel are not being translated when loading the grid or after draging and drop a column into the group panel.......the traslations are only being done when colapsing or expanding the grid rows.

I think this is because the Group Panel doesnt have elements when the ItemCreated Event is fired.....so my questions are:

1.- When is the Group Panel being populated.
and/or
2.- is there a better way to localize the Group Panel elements.......

This must be done in CODEBEHIND.....srry about the caps, are only to emphasize the fact that I cant use the fieldAlias property due to the fact that 3 different language translations must be done and the texts are changed so oftenly.

Thks in advance

Hi,

In loaded event of tree I look through nodes and get reference to <img/> inside each node which is templated through <NodeTemplate>.I want the user to be able to left click on it and see context menu (same context menu as user can see by right clicking on any tree item). This is how I add 'onclick' handler to <img/>:

Now when I click on img I can see the context menu, but no events are fired and obviously postback doesn't happen (regular right click based menu works as expected). I tried with treeView.showNodeContextMenu but it fails internally on get_contextMenu call.

How to fix that? :) Thank you!

PROBLEM SOLVED

On the website there seems to be missing an explicit explanation that After you do an CallbackUpdate you have to add a Javascript function where you do a sender.show() so your notification window could be seen on clientside.

**********************************************************************************************************************************************************

Hello, I started using RadNotification control today and I have encountered a problem that is really weird.

The problem is that I am using a really simple implementation of this control using a callback method on the server, and this the notification doesn't Fire up when the event ends... in Fact it never FIRES up anytime the event ends.

Here is my code (I used the same code provided in the Demo website) REF: http://demos.telerik.com/aspnet-ajax/notification/examples/updateinterval/defaultcs.aspx

The only difference is that I am not using the QuickStart Library or Event Log Console.

(CODE)
