JScript Null reference exception when firing InitInsert ItemCommand

Hi:

I'm developing some pages to use as templates, and one of them has a radlistview in the left side. There seems to be no problem when firing the Initinsert ItemCommand when that radlistview has items, but when firing it with no items, I get a JScript null reference exception. It's driving me nuts, since I cannot find what is causing the exception. Maybe I should manage some event, I don't know... I hope someone can lend me a hand on this.

Here is the code:

RadWindow load and close problems

Hello,

In my current project I am using the RadWindow object quite a bit and I am running into a lot of trouble with it.

One page in my project calls the RadWindow object twice. The RadWindow populate data in a radgrid and on the select command of the grid the RadWindow should close. The RadWindow is called from server side code.

The issue I have noticed is that when I first load the page and make the RadWindow call, the RadWindow page_load event gets called once, the next time I call the RadWindow object from another location on the same page, the page_load of the RadWindow triggers twice. The page_load triggers as many times as I call the RadWindow object from the page.

Combine the above with the radgrid select. If the radwindow page_load happens twice then the radgrid select happens twice. The normal behavior of select in my code is to pass the selected item to the parent page and close the RadWindow and return to the parent control. However the select of the radgrid triggers as many times as the page_load event triggers.

Could you please let me know how to handle this scenario.

Thanks!!

Below are snippets of my code.
Parent page from where the RadWindow is loaded.

<telerik:RadWindowManager runat="server" ID="WindowMgr" Skin="abc" EnableEmbeddedSkins="false">

</telerik:RadWindowManager>

Javascript on the parent page to handle the OnClientClose event.

<script type="text/javascript">

function SetTextBoxValue(oWnd, args) {

//check if a value is returned from the dialog

var arg = args.get_argument();

if (arg) {

//do something

}

</script>

Code to invoke the RadWindow server side

Dim popUp As Telerik.Web.UI.RadWindow = New Telerik.Web.UI.RadWindow()

popUp.ID = "selectOrg"

popUp.OnClientClose = "SetTextBoxValue"

popUp.NavigateUrl = "someurl"

popUp.VisibleOnPageLoad = True

popUp.EnableEmbeddedSkins = False

popUp.Skin = "abc"

popUp.VisibleStatusbar = False

popUp.VisibleTitlebar = False

popUp.Modal = True

popUp.Behaviors = Telerik.Web.UI.WindowBehaviors.None

popUp.ShowContentDuringLoad = True

popUp.Height = Unit.Pixel(450)

popUp.Width = Unit.Pixel(500)

WindowMgr.Windows.Add(popUp)

Code in the select index changed event for the radgrid in the radwindow

ClientScript.RegisterStartupScript(Page.GetType(), "ey", "returnToParent('" + strSomeValue + "');", True)

Javascript code to handle the returntoParent function of the radwindow

function returnToParent(refControl) {

//create the argument that will be returned to the parent page

var oArg = new Object();

//get the control to modify on Parent

oArg.ControlToModify = refControl

//get a reference to the current RadWindow

var oWnd = GetRadWindow();

//Close the RadWindow and send the argument to the parent page

if (oArg.ControlToModify) {

oWnd.close(oArg);

}

Clear selection RadComboBox

Hi,

I have a page with several RadComboBoxes.

Each combobox filters on the text that is typed (for instance, I type "er", eric, frederic, meredith appear in the dropdown).

That poses a usability problem when a user wants to select another item in the list, the other items are not visible when some text is typed in the combobox. Each time, the user has to manually select the filter text and delete it. Is there a clean (preferably built-in) way of clearing the text in a RadComboBox ? (a "clear selection" option in the dropdown, a "X" button on the selecteditemtemplate field ?

Thank you,

Eric

Reshowing radmenu after postback

I have the following situation:

I have a radmenu being used as a context menu on a radtreeview. When the user clicks (or right clicks) on a node in the treeview, the node is then selected and I need to retrieve some data from the database to populate some textboxes with data relevent to the newly selected node.

The problem I am having is that, of course, when the page is posted back, my context menu is then closed. I am trying to use the menu.show command, but it wants a dom event as a parameter. In other places I've just used the args.get_DomEvent to grab the event off of the event arguments parameters that are sent to the method. But, I don't have an "event arguments" parameter if I'm trying to just register a script to open the menu as soon as the page gets done loading.

how can I reshow my menu after the page refreshes following a postback?

Problems installing RadControls for ASP.NET Q3 2007 over later versions

I need to update a legacy Web App using Telerik RadControls for ASP.NET Q3 2007, I have later versions Q3 2009, Q1 2010 and Q2 2010 also installed, I get an exception on installing Q3 2007, 'Error creating virtual directories, Exception details: Unknown Error(0x80005000). Has anyone else experienced this problem and found a workaround? I am using VS2008, I also have VS2010 installed. I have tried uninstalling the later versions first, but installation of Q3 2007 still fails.

Hello Telerik,

Hello Telerik,

I'm not sure if you're aware of the issue described here:

http://brianseekford.com/index.php/2010/04/18/bit-by-telerik-redirects-in-my-ajax-panel-not-working-with-net-4-upgrade/

I had the same issue till the moment and removing RadCompression fixed it. I hope that helps someone and hope you're fixing the issue soon.

Regards,
Apostol Apostolov

P.S. Sorry for the thread's name, I got distracted.

Help with downloading file

Hello, I am trying to download a file from SQL Server...here is the method I normally use.

Private Sub gvMain_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles gvMain.ItemCommand

Dim fil As Byte() = arr(0)

Dim nam As String = arr(1)

Dim ext As String = arr(2)

If Not fil Is Nothing Then

Response.Clear()

Response.AddHeader("Content-Dispostiotion", nam & "." & ext)

Response.AddHeader("Content-Length", fil.Length.ToString)

Response.ContentType = "application/octet-stream"

Response.BinaryWrite(fil)
