RadWizard Next button when clicked IsPostBack = False

I have a standard RadWizard. It is within an RadUpdatePanel. On page load I have a chunk of code.... Product is a global Object

If Not IsPostBack Then

'do something

* Session("Product") = Product

Else

'do something else

* If Not isNothing(Session("Product")) Then

Product = Session("Product")

End If

End



* = Breakpoint

I have placed a breakpoint within 'do something' and one within 'do something else'.

When I run the page the 'do something' code runs as expected. The 'do something else' is not run - as it's not a postback this is correct.

Whenever I click the Next button of the RadWizard the 'do something' code runs - hovering over IsPostback shows that it's value is FALSE... but it should surely be TRUE. If I continue from this breakpoint the 'do something else' code runs - hovering over IsPostback now shows it's value to be TRUE.

Why are both the Not IsPostback and the IsPostback code executed when the Next button is fired?

RadScheduler MonthView rsAptResize is not being rendered

hi all,
I am using RadScheduler in monthview. I made the appointment editable, clickable on clientside ( using clientside event, I am familiar with those).... But I am not able to make the appointment Resizable, Moveable.
( it is Resizable and Moveable in TimelineView).

I examine the HTML that being rendered, I notice that the Appoinments HTML does not have the DIV rsAptResize as it does in Timelineview. (refer to the attachment)

What could possibly caused this ? Can someone shed a light. May be someone from Telerik is familiar with the way the control is being rendered...
( I customize the RadScheduler and Appointment template, can this be a reason why? But it work find in TimeLine view? And in MonthView, I apply the same process. In MonthView the Appointments are clickable but note moveable...)

regards.

Add OnClick handler to anchor tag in document manager

How do I add a onclick handler to my DocumentManager control? I can alter the href or URL property from a ExtendedFileProvider to add "javascript:clickHandler()". But this isn't good practice.

I have both a LinkManager and a DocumentManager. How do I add an onClick to the <a> tags that get generated by these controls?

Thank you!

Drop Down List error in FormTemplate

I am getting an error:
'ddlWebPages' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

This happens only when I click the Add New Record button on the grid. the ddlWebPages has no issues when I am in edit mode.
I believe this has to do the the snippet SelectedValue='<%# Bind("security_webpage_id") %> of the dropdownlist.
I searched for solutions but none of them worked. There was one suggestion for SelectedValue='<%# Eval("security_webpage_id") == null ? null : Eval("security_webpage_id") %>'. That didnt work for me. Has anyone dealt with this issue? HELP! I am so close to finishing my grid.

Dynamically created textbox in RadGrid

Hello,
I'm have a RadGrid with 2 template columns. During ItemDataBound I'm dynamically creating a textbox and adding it to the Grid like this:

GridDataItem gdi = (GridDataItem)e.item

TextBox tb = new TextBox();
tb.ID = tbID;
tb.EnabeViewState = true;
gdi["column name"].controls.add(tb);

"Colum name" is a template column in the grid

I have another template column with a button in it that is created at design time. When I click that button I want to be able to find the dynamically created text box in the same row of the grid and read it's value.
How do I accomplish this?

Thanks in advance

Large performance hit on e.Item.Expanded = true

In the ItemCommand event on my RadGrid I have the following section:
if (e.CommandName == RadGrid.ExpandCollapseCommandName || e.CommandName.Equals("RowClick",StringComparison.InvariantCultureIgnoreCase)) {
e.Item.Expanded = true;
e.Item.Selected = true;
}

The e.Item.Expanded being set to true is taking 10-14 seconds to resolve, what could be happening that would cause such a large performance hit?

Get current Url from radwindow

Hello, I am struggling getting the current url for the radwindow. I always seem to obtain the original url.

I have a radwindow hosting a webpage where I am able to perform searches internally, Just as google, yahoo etc, the url is populated with a string of information identifying the performed search. I need to pull the new url from the radwindow and pass it to a model popup I am using to save the string.

I have tried several options but none seem to get anything but the original url.
radwindow.get_NavigateUrl()
radwindow.Geturl() - doesn't work at all.
document.getElementById("radwindow").src

Please help,
thanks.
