hi,

i am new in programming

i want to fill raddropdownlist manually using entity framework (DataSource,displaymember,valuemember) whats the code for that

also i want to know when i made update using linq how i pass raddropdownlist  value member to id table by where id=id whats the code i write i tried search in google but nothing found i need help please 

I'm using a winforms radvirtualgrid to display pages of data.

I allow the user to apply search strings and filters.

When data needs refreshing, I first run code to perform a total count of records on the database, then similar to pull a page of 100 records..

If I have several pages of data, zoom to the last page, then the correct number of pages is told to me in the paging panel.

If I then cause a search that retrieves less data then my code range checks the grid.pageindex against grid.totalpages and adjusts the page inded downwards.

But I've found that if Im viewing the final page of data, and a new search returns no data, then my range check fails and the pageindex is not changed in the display on the paging panel. i.e line 8 of the following code snip does nothing. I've also tried setting pageindex to zero (fails in the code), and turning paging on and off on the grid in the hope it refreshes.

I'm guessing it's something to do with there being no data. Is this a bug please, or can I do anything to reset the value to zero?

Hi,

I'm working on a project that utilizes a few RichTextEditor . When I initially start the application and have a window open with 3 RichTextEditor memory usage is 62mb.

This is fine, but when I open a window that has another RichTextEditor in it memory jumps from 62mb to 132mb (this window has two textboxes and a RichTextEditor). When closing this window memory drops only 10mb so memory is at 121mb.

If I open and close the window 5 times in a row memory usage stays at 205mb. In my application this window will be opened frequently. I have tried explicitly disposing the RichTextEditor, but doesn't seem that GC is picking it up at least not quickly (I left the application running for about an hr and it didn't drop much about 5mb).

I understand themes are loaded as static resources so once a window loads it shouldn't have to load theme resources again?

Note this is an MDI window that is docked on the RadDock. Any direction you may have would be greatly appreciated. 

Thanks,
Jacob

I have a picturebox1 and radtextbox1 radbutton1

I show pictures in picturebox1 from file

I need to click radbutton1 to add image from picturebox1 ,and text from radtextbox1 above it and resize image to 8.27 inches width , 11.69 height stretch

I could add the item but the big images appear so big 

I used this code in radbutton1 click event :

Image image = pictureBox1.Image;
            RadButtonElement item = new RadButtonElement();
            item.Image = image;
            item.Text = radtextbox1.Text;
            radCarousel1.Items.Add(item);

How do I disable context menus "EditHeader" and "EditFooter", so that they don't show up?

How do I remove (rather than disable) context menu item "Hyperlink..."?

I want to create a new RadDocument and serialize it to byte array. And I want to set default font to something else than "Verdana". Let's use "Comic Sans MS" size 24 for instance. What should I do between "new RadDocument()" and "RtfFormatProvider.Export" (also "XamlFormatProvider.Export") so that word "Verdana" is not found in serialized byte array?

Also, when I want to deserialize this byte array into RadDocument are there some extra steps I should do to prevent Verdana from somehow creeping back in (unless the user explicitly changes some text to Verdana)?

Hi,

I have a commandbarmaskededit box that is not restricted users to numeric entry only. In the objects properties under the expanded CommandBarMaskedTextBoxElement I have the Mask as ### and the MaskType as Standard and I have also tried it with Numeric. Neither options prevent the user from enter any alphanumeric characters instead of restrict in to just numeric. Thanks!

Hi. I'm using Telerik UI for WinForms Q3 2014(v2014.3.1104.40)

I have a problem about memory leak between creating and disposing RadGridView.

I already have searched many threads, but I coudn't find the answer.

So I make a small test project to test the memory leak.

In image files, one tb(RadGridView) is just created. Not includes data binding or any columns/rows.

Just empty thing.

And using 2 buttons, I create and remove tb repeatly.

(In removing process,

tb.controls.Dispose(), tb.Dispose(), tb = null, even GC.Collect() are performed.)

However, memory leak is increasing more and more.

I tested using datagridview in C# basic control and it doesn't make a leak.

If I did a mistake, tell me what's wrong.

Need a solution to prove this case.

Best regards.

img01.png = tb is Dock.Left. And 2 buttons for disposing tb, creating tb.

img02.png = source code of remove/create button event.

When a theme is applied to ribbon bar of rich text editor the icons are also changed. When I extract in code Image property of some button (for instance richTextEditorRibbonBar1.buttonInsertImage.Image) I get the default non-themed image. But themed image is shown in the form. How do I access themed image from buttonInsertImage? How do I access this image from theme repository?
