I have a RadGrid that I would like to change the size of the page and the current page number depending on the URL.

I can query the URL and retrieve the data that I would like, and attempt to apply it like so:



I do this in the Page.PreRender. The CurrentPageIndex will save correctly, but unfortunately the PageSize does not change.

I have attempted to paste this code into the function I call to fill the grid as well as the NeedDataSource(of course removing the rebind call) to no avail.

I am just wondering why one would save but not the other? Also I would like to know if I am attempting to change the PageSize in the backend correctly.

As far as I can tell, newer versions of WebAPI return ISO8601 dates instead of the traditional Microsoft format that was /Date(  )/.

The rendering script has the value of "g" being null when attempting to parse the date and the appointments never bind and the Scheduler breaks with the exception shown in the Locals list in my screenshot. I would hate to have to revert back to using the old format.

Any work around for this?

I am having a similar problem, and I generated a short example to illustrate the problem. We are using a timer, but it happens to be a bit longer in cycle than the one supplied here. It just takes longer to run out of memory if the timer is longer. Note that the more items that are added to the chart, the larger the memory leak.

I also took the liberty of looking through the Telerik source code and discovered that RadChart contains 2 Chart objects, one directly, and one indirectly through MapAreaBuilder. RadChart does not implement Dispose, so these items hang around much longer than they should. MapAreaBuilder also does not implement dispose, and it should as well. The basic idea is that if a class includes an object that implements IDisposable, the containing class must also implement IDisposable and dispose of the Disposable objects it contains. Yes, RadChart does inherit from Control that implements IDispose, but Control does not know to dispose of the 2 Charts that are contained in the RadChart object. In other words, RadChart needs to override Dispose(bool) and dispose of the Chart and the MapAreaBuilder if the parameter passed in is true. MapAreaBuilder needs to derive from IDisposable, implement Dispose(), Dispose(bool) and ~MapAreaBuilder().

I am trying to open a window with a label set from code behind.
The window opens but the label is not set


This is how the popup is declared:


And this is the WebMethod


Not sure what I am doing wrong.

I am using advanced binding and creating dynamic columns during Page_Init event.
Everything works fine except column groups.

I am creating column groups based on my data and then linking them to columns eventually in page_init event.

Below is the code I am trying to use. Everything is fine on first load. When we try to refresh grid, nothing works. I am getting "Invalid Column Name" error.


            DataSet dsSubmittals = new DataSet();
            DataSet dsCycles = new DataSet();
            string SubID = Session["SubmitalID"].ToString();
            if (Session["SubmitalID"] != null)
            {

                //for (int k = 0; k < dsCycles.Tables[0].Rows.Count; k++)

Hi,

I use the RadEditor inside a input form with dynamic content. Dependent of the selected record in a Radgrid different input control become visible. When an input control is not visible, its replaced to a seperate div to make room for other input controls. Because the RadEditor is replaced on the DOM I call editor.OnParentChanged() to let the RadEditor behave as expected especially in Firefox and IE 10 and lower. If I don't the RadEditor steals focus and its content becomes empty.

This works great when the RadEditor becomes visible, but when the RadEditor becomes invisible it still steals the focus.This is a problem for pressed shortkeys in the RadGrid to navigate through records because they stop work after the focus is stolen. The content of the RadEditor stays filled when it is invisible as expected.

The strange thing is, the focus is not stolen the first time the RadEditor becomes invisible.

Any ideas what goes wrong in my situation?

With the Microsoft Validator controls (RequiredFieldValidator in this case) the typical behavior is for validation logic to run when you tab out of the field, or on submit. 

I have noticed with RadComboBox this is **not** the case, even in your own online demo. Rather, with RCB validation *only* occurs when you attempt to submit. Is there any way to force this to validate on tab out? Typically the field would look something like this in code:
