Hello,
I am using RadSlidingPane in my web application. I have 4 RadSlidingPane vertically as shown in attachment. There are 4 tabs chart, navigator, document management and admin. My problem is that if I dock any one tab(for example chart) and click on other tab(for example navigator) then chart is shown in back as truncated. I want that is user click on navigator then chart should not be shown. How can I do this??

RadAjaxpanel is refreshed with browser refresh

I have some content initialized in RadAjaxPanel which gets changed if I click next/previous buttons inside that panel and content inside that panel gets changed on every button click. The problem is that if I hit browser's refresh button, content gets changed and go to first record which was initialized when page was loaded first time. How can we stop that browser's refresh effect on content inside RadAjaxPanel?

Pressing enter key in advanced form lost focus

I was testing my own built RADScheduler page and I found a bug.
My page will always start an advanced form to insert, when I press the Enter key, the focus dissappeared.

In my masterpage I have a Log Out button. Every time when I press the Enter key, I get logged out. How can I get the focus on the advanced insert form?

In my advanced form I have one custom attribute.

This problem also happens with the demo RADScheduler page. I use Internet Explorer 9 to test it.

I don't have any code in Javascript or in the CS file:

RadGrid.ClientSettings.DataBinding

I think that there's been a problem with the Copy'n'Paste inheritance used to put together the man page for this property.

All of the content refers to the ClientSettings class rather than the DataBinding class you would expect.

I don't know if the man pages for this class and it's properties are missing or just inaccessible.

Displaying blank grid

I have used Hierarichal radgrid. In that i have to display empty according to a condition.

Have used below code on page load event:
if (PrimaryID > 0)
                    {
                        PopulateData();
                        //data will be populated
                        AttributeNameGridBind();

                    }
                    else
                    {
                        this.rgdLabTest.MasterTableView.NoMasterRecordsText = Utility.ContentFetcher.GetResourceContent("RES_035", BOL.Classes.EHRSessions.Culture);
                    }

But grid is showing as solidline istead of no record to dispay message.
Can anyone suggest something.

I want the message from codebehind.

Missing MediaManager?

I'm using RadEditorMoss v 5.8.15 and I'm not finding a MediaManager.gif in the ToolImages folder. Is this a sign that I installed the light version? I have the Ajax pack so I should have access to the full thing right?

Problem with dynamically added controls.

Hi.
I create a panel bar item, and attach ItemTemplate to it in the code-behind.
Everything looks ok, controls added to panel bar display just fine, but when i try to access them in code-behind (after a button on page being clicked) RadPanelITem that contains dynamically added controls doesn't show them anymore, its Controls collection is empty (but it's not empty after i add the controls) and findControl returns null.
What am i doing wrong?
