RadChart

Hello,

We are using Telerik.web.chart charts and then convert them to images using chart.Save()

I works fine when I use from web application, however if I invoke using windows service it throws an

"Object reference not set to an instance of an object." error.

Stack trace suggests at Telerik.Web.UI.RadChart.Save(Stream stream, ImageFormat imageFormat).

however radchart object itself is not null but scriptmanager property is

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request

is there a way to generate images using telerik.web.UI outside http context or is it a completely different error.

cheers Vijay

Grid Losing Data in Multiview After When Any View Is Updated

Hello,

I have a strange problem with the behavior of radgrids that are located on different views within a multi-view after any any update is performed within any of the views themselves. After initially populating the the various grids within the different views, everything looks fine and switching between the views causes no issue. However, as soon as I do anything that initiates an update it causes all of the radgrids within the various views to lose most of their information and only display partial information of the first line. I have included screenshot below of what one of the grids looks like after initial databinding and then what it looks like after updating any of the views in the multiview.

I have tried hooking into the NeedDataSourceEvent, but that does not do anything to help the problem. Additionally, I also tried setting the RenderActiveView mode to both false and true and this did not solve any problems either. One other thing to note is that I don't even have to update data or controls within one of the views for this to happen. For instance, if I simply click a button that has code behind to change the view that is currently active, the same problem happens.

Following is the markup for the multiview:

Grid Javascript error trying to collapse group

var d=typeof(z)==="undefined"?false:true;
if(typeof(z)==="undefined"){z=l;
}if(!this._owner.ClientSettings.AllowGroupExpandCollapse){return;
}var x=l.id.split("__")[0]; <-- 4094

l.id is not defined at line 4094.

The page containing the datagrid with grouping is in an iframe.

l.name is the same of our web apps iframe, why should the javascript need to know the id of the page.

The javascript appears to be for the radgrid.

Any ideas...?

[Solved] Remove Check All Check is not working as expected...

PLEASE SEE ATTACHED IMAGE for screen captures...

I have a bit of code that is called to remove all checked items in various radcomboboxes with checkboxes...

My code works great to remove their selections, but if they use the check all option and then opt to clear all selections (a button event) all the checked items are unchecked EXCEPT for the check all...

function clearCheckedItems(combo) {

for (var i = 0; i < combo.get_items().get_count(); i++) {

combo.trackChanges();

combo.get_items().getItem(i).set_checked(false

);

		// The following code I was hoping to use to clear the checkall box...

//var element = combo.get_dropDownElement();

//var checkAll = $telerik.$(element).find(".rcbCheckAllItemsCheckBox");

// So what do I need to do at this point to clear the check all checkbox...??

combo.commitChanges();

}

FilterExpression Linq Syntax?

What exactly is the syntax for the FilterExpression? Sometimes it looks VB-like, other time C#-like. For example:

IsEmpty: (it["Member"] = "")
NotIsEmpty: (it["Member"] <> "")
IsNull: (it["Member"] == Convert.DBNull)
NotIsNull: ((it["Member"] != Convert.DBNull))

The first two linq expressions use = and <>, which is VB-like, but the second two use == and !=, which is C#-like!

Note: These were generated one after the other on the same grid with no other changes. Column type is GridBoundColumn (created in code-behind) with DataType = System.String.

ImageManager Broken After update to 2013.1.220.40

I have a Rad Editor with the ImageManager enabled. The image manager displayed correctly until up updated from 2012.2.912.40 to 2013.1.220.40.

It is almost as if the default skin is no longer being applied. I have not skin specified on the RadEditor or in the Web.config.

See attached images.

Again, this worked until I updated telerik. No other changes were made.

Paste at Cursor, using custom RadComboBox trouble in IE

Hi,

We’re facing some problems Replacing the Custom DropDown of the RadEditor with a RadComboBox so users have the ability to type/find their item. When you click a couple of items from the dropdown at startup, all goes well. But when you type “Sec” for instance (to search for the “Second item”) and click that one with the mouse, it will be placed at the beginning of the RadEditor.

After having typed, finding another item goes very strange aswell.

The problem arises in Internet Explorer. In Chrome it seems to be workable.

How would we solve this issue for our main users, using IE ?

I've seen this recent post which was the same, besides having the ability to type/search the combobox.

I’ve attached a demo application including the scenario. We’re using Telerik version 2013.1.305.40:
http://www.gildebt.nl/RadEditor.rar

Yours,

RADComboBox issue in migration from 3.5 to 4.0

Hi,

I have migrated my application that uses Telerik.Web.Design version 2009.3.1103.35 and Telerik.Web.UI version 2008.3.1125.35 dlls from 3.5 to 4.0. I am receiving the following error while doing any postback operation like cancel in RadGridView row. Pleas find the attached error screen shot.

I had refered to the patch provided by Simon at http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-vs2010-bug.aspx. But tht fix is not working for every form in my project.

Again, I have alos tried by replacing latest telerik dlls, but with this all web pages are working fine except the one in which i have used many telerik controls and that page is not even entering into Page_Load event.

Please guide us on this issue as I have a very urgent delivery next week.

Thanks,
Anuradha

RadGrid - Nested grid using nestedviewtemplate

Hi,

I have scenario here where in I have a List of Employess and each employee in turn has a List of Projects.I have created a master grid with its nestedviewtemplate having a child grid to display the each employee and his associated projects.
i.e We will have a collapsible option for the master grid and expanding it,it would display the projects associated for that particular employee.This works fine.

Now,for my second scenario,I need to display all projects irrespective of employee using the same grid having nestedviewtemplate.In this case,I should not be having the collapsible option,and it should load the grid with all projects.

how do I achieve the second scenario without the collapsible symbol with data being loaded on load.

Thanks
