Invalid Parameter

Hi

Sometimes the following exception is thrown in our application:

Parameter is invalid.

ved System.Drawing.Region.GetHrgn(Graphics g)
ved System.Windows.Forms.Control.GetHRgn(Region region)
ved System.Windows.Forms.Control.OnHandleCreated(EventArgs e)
ved System.Windows.Forms.Form.OnHandleCreated(EventArgs e)
ved System.Windows.Forms.Control.WmCreate(Message& m)
ved System.Windows.Forms.Control.WndProc(Message& m)
ved System.Windows.Forms.ScrollableControl.WndProc(Message& m)
ved System.Windows.Forms.ContainerControl.WndProc(Message& m)
ved System.Windows.Forms.Form.WmCreate(Message& m)
ved System.Windows.Forms.Form.WndProc(Message& m)
ved Telerik.WinControls.UI.RadFormControlBase.WndProc(Message& m) i :linje 0
ved System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
ved System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
ved System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

No line of code is specified in this exception. One of our customer is using Citrix and this exception is more frequent there.

How can I solve this problem?

The exception is oftenly thrown while refreshing data in RadGridView, RadDatagridviewComboboxes and other controls. Actually I can not reproduce this exception on my machine but in the situation told by customer, we are refreshing data.

Telerik version used by application is v2011.1.11.419.

Any help would be appreciated.

Thanks

Regards

button to loop on selected rows with btnnext and btnprev buttons

hi everybody is there a way that we could loop to selected rows using two buttons button1 and button2, like for example i want the small arrow to point to the first selected row with document name f10_oct1_en.pdf, currently it is pointing to f36_may07_en.pdf, and each time i click the button it jumps to the next selected row which in my case if the arrow is on f10_oct1_en.pdf will go to f21_dec17_en.pdf, same thing will happen to the prev button only going backwards..
i have attached a png file on the thread so you could understand what i mean...
thank you very much...

General inquiry on which Telerik product to use for a project

I have used Telerik ASP.net AJAX and Reporting in the past. I now have a project that seems to lend itself to WinForms, but my concern is that I would rather have it be a web application. Here is what it needs to do:

integrate with a currently working classic asp web program (not a problem as we already have a .net component doing this)
have a bunch (25) of forms that the users will be filling out that will save the data to a database. the forms are some yes/no questions, some fill in, and some drop down choices: pretty basic stuff just collecting data.
some users will only be viewing these forms and their data; need to have them open automatically in a pdf.
in some cases, if the user answers a certain question with a Yes, we need to ask the user (probably with a popup box) if they want to do something, and we have to save that response to a separate database.
would like to have some of the questions appear/disappear based on responses to other questions.
need to be able to work offline and then update the database when they are connected at a later time

I would prefer that they don't have a standalone application that has to be installed. That is my concern with using the WinForms. Any advice would be appreciated.

Thanks, Amy

How do I change the Font Size on the tabs?

I did some searching around, but couldn't find an answer to this.

I have a PageView with 2 tabs that I have set to use the Office2007Silver theme. I have added images to both of the tab and while those look nice the text on the tabs is too small and I would like to increase it.

I have tried changing the font size in several places, but none of them change the font.

I tried directly in the properties of the PageView object.

I also expanded the PageView Tasks and clicked "Edit UI Elements" because this section helped me change properties of buttons I'd applied a theme to. I tried the PageViewLabelElements, StripButtonElements... eventually I changed the font size for every single element in this section, but nothing changed.

So where/how do I change the font size on a tab on a PageView object that has a theme applied to it?

GridViewCheckBoxColumn use large dll reference

I am using telerik GridView to modify a Visual Studio extension sln. the Gridview has checkboxColumn, textColumn and ImageColumn. CheckboxColumn uses Telerik.WinControls.UI which is a ~7MB dll file. Adding a 7MB reference file within Visual Studio extension package is not acceptable. Is there any other way I can use Checkbox column without referencing the large dll file.

Branching

i would like to setup a wizard to have a page right after the Welcome page that determines which of the next sets of pages would be "executed", then, returning to the "main" wizard execution.

basically, it's ... Welcome->option page-> ... branched pages ... ->common page1->common page2->finish.

for one of the branches, there are 4 pages, while in the other branch, there are 2 pages. after the completion of either of the branches, clicking on the Next button would go to "common page1" and so on. clicking on the Back button (from "common page1") would go back to the last page of the branch.

thanks,

pete.
