I created a label on a tile,and then I added on tile as a children like below:
private RadTileElement _radTileElement;
public void AddText()
{
var element=new RadLabel
{
ForeColor = Color.White,
Text = "<html><size=20>" + @"This is a text"
};
_radTileElement.Children.Add(element.LabelElement);
}
The problem is,the tile is not responding at all,i mean,is clickable and drag&drop just on edge of the tile,why???How can fix it?

RadRichTextEditor prints the code as follows:
RadPrintDocument document = new RadPrintDocument();
document.PrintPage += (s, e) => { action?.Invoke(); };
richTextEditor.PrintPreview(document);
Does RadSpreadsheet have such a Print/PrintPreview method?

Hello.
I have a logic controlling whether the cell is editable or no. It is checked on cell begin edit:
private void CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
e.Cancel = !controller.IsEditingAllowed(grid.CurrentCell);
}
Now I need also to control focus: if the cell is not editable, it shouldn't be possible to focus on it using the tab key (preferable using mouse also) even in read mode.
Is this possible to implement this?

Hello,
I have a RadListView with custom SimpleListViewVisualItem which has a button. When an item is selected in the listview control the button is visible and hidden when it is not (only one button shows at a time on the selected index). This is working just fine using the "VisualItemFormatting" functionality.
Now I am trying trying to enable a different mode in the interface which eliminates the functionality that the button provides so should remove the option of the button for the user (hide it). I am not sure how to "repaint" the listview control so that the VisualItemFormatting function can kick in and remove the button on the selected index and put it back in when returning to that mode.
Any suggestions? I've tried updating the list and the viewelement but it doesn't seem to have an effect.
Thanks!

Hello.
How can I change the pin state (pinned/unpinned) of some page of RadPageView from code? RadPageView.ViewMode is set to Strip.
Can this be done, when the RadPageView.ViewElement.ShowItemPinButton = false ?
Thank you!

In regular winforms controls, where there's a touch screen, if a textbox gains focus then the touch keyboard doesn't automatically popup. However automatic popup works correctly on winforms VS RichTextbox control.
see the following stackoverflow forum thread
https://stackoverflow.com/questions/36179917/automatically-pop-up-tablet-touch-keyboard-on-winforms-input-focus/40259606
I only discovered the problem a couple of days ago as I usually use keyboards I've developed myself which are embedded in my windows. We've moved into the Chinese market with our product and because the Pinyin keyboard is so horribly complex we thought we'd opt to use Windows own touch keyboard despite not being able to host it nicely in the windows. Whilst researching and testing we discovered in horror that textboxes wouldn't support it.
My only option is switching out all textboxes and there's 100s of forms :( .
I've a 2nd problem in that I can't test on my development pc as it doesn't have a touch screen, the touch screen emulator came after vs2010. So I can't just throw one of your radtextboxes on a form and try it out.
So my question is, if I globally switched out all the textboxes with RadTextBox or radtextboxcontrol, will they automatically pop up the touch keyboard? (We're updating our old app a form at a time with telerik controls)
thanks

Please look at the attachment,
From the first column to the third column, my expectations are like the fifth column.
Remarks: I hope to support word (or excel) replication in the entire row (full column)

Hi,
I have RadGridView object and I want to Validate user input. there are two coulmns. when the user enters a value which is greater than 0 for column1 then if the column2 is greater than 0 an error must be occured and also this is the rule for coulmn2 (that is if coulmn2 value is greater than 0 and also column1's value is greater than 0 the error occurs.)
the problem is that first of all I must check the value of a cell. but when I check an error occurs and tells that the value is null:
if(column1.currentrow.column["MyCoulmn"].value!=null) // Runtime Error: Value is null, use new keyword!
how can I validate column content without getting this error. also when I try this:
Convert.ToInt16(column1.currentrow.column["MyColumn"].value.ToString())>0
FormatException Occurs. While my value is 2 for example, Why such error occurs?
Thank you, please help me.

I read this: "Commercial WinForms applications deployed to Your end users. In this case, you may deploy the Telerik assemblies together with your application with the sole exception of the Telerik.WinControls.UI.Design.dll assembly. The Telerik.WinControls.UI.Design.dll assembly may not be deployed to end-users under any circumstance."
And then if I release a free or trial version I'm required to protect all assemblies. If I don't sell my application with a free version or a free version with a trial I can deploy all the telerik assemblies as is with the exception of Telerik.WinControls.UI.Design.dll?
