I keep running into this increasingly annoying nuance when using a RadMaskedTextBox wherein once the field gains focus, the cursor doesn't seem to position itself at the beginning of the field. Instead I get something like this;
Which would come from for example, the code below. Notice in the example the cursor starts 7 spaces from the beginning of the field. Which is exactly the number of #'s I have set in my Mask to allow numeric input of 7 characters as shown below.
<telerik:RadMaskedTextBox
Value="{Binding Path=Parameters.Blah, Mode=TwoWay}"
MaskType="Standard"
Placeholder=""
Mask="#######"/>
How can I get the cursor back to the beginning of the field when it receives focus while keeping my numeric input length? I have the suspicion I'm missing an inane detail here. Thanks in advance.
I'm not sure what you're asking for... but if you just want to get the cursor in the beginning of the radmaskedtextbox on focus (once you are focused, you can click wherever in the textbox to move the cursor) you should use this property:
SelectionOnFocus="CaretToBeginning"

Today I tried using Windows Forms for the first time, which went pretty smoothly until I tried setting the text of a label to "0 lines", which was displayed as "lines 0" in the actual program. I tried a couple of other inputs for the Text property, and it seems the leading number in the label is always moved to the back. I couldn't find any property in the label describing some sort of numerical formatting, so I was wondering were this rearranging came from and what I could do to disable it. Thanks in advance!

As CodeCaster said in their comment, I simply had to change the RightToLeft property.
I have a text block which I have binded to a data field in my c# code which has a setter and getter.
I can enter numbers fine into the text block via the keyboard
The c# code can also set the text value.
I have seen this weird problem where I starting typing a number and I think at the same time the text field is being set by the setter. This causes the cursor to jump from the right where I'm typing to the left, so while I'm typing the number the what I type is not what is seen in the text block. This is because the cursor jumped locations in the middle of me typing. Is there any way to control the cursor so it's always at the right???
Here is an example.
I want to type 1234
I'll type 12 (cursor at right)
I think at this point another of the code will echo the same value 12 and set it.
Then the cursor will jump to the left
then I will finish typing 34
The final value will be 3412
Thank you very much for any ideas!!
try to set UpdateSourceTrigger=LostFocus, to prevent updating the source too often.
check your Property-Setter if RaisePropertyChanged is only called when the new value differs from the old property-value.
We need to use the built-in WinForms tooltip control to display a very long tooltip (about 4000 characters) for one of our controls. But if we do so, the form freezes for a minute or two when we place the mouse pointer into the target control to see the tip. And nothing happens after that.
We experimented and detected that the standard tooltip starts to work very slow when it has about 2000 chars, and the situation becomes much worse when we increase the number of chars. Is it a known issue, and is there any workaround for it? Please, don't suggest to trim the tip text - we need to display the string as is.
When you assign a string of text to a ToolTip, part of the process of drawing it involves calls to USP10.dll which handles Unicode layout of characters on screen. I was able to see this by looking at the stack trace while the program was freezing. The performance of this layout is terrible for long strings.
Disabling Visual Styles for the application (commenting out EnableVisualStyles()) fixed the problem - the tooltip displays immediately, though this is not an optimal solution.
I kept looking and found this page which indicates the problem may be linked to layout of long strings where word-wrap is necessary. By inserting line breaks into the tooltip text, I found that the string displayed immediately. So, if you can determine where to insert the line breaks manually, the ToolTip should display quickly.
What about using another Tooltip , i.e. HtmlToolip?
In our Silverlight page, I got comboboxes with different values. When selected, some values are too long to fit in the collapsed combobox.
I would like it to ellipsise ("System Use..." with three dots in the end).
In the dropdown the full name of the value can be seen, but when collapsed I would like the selected value to ellipsise. It feels like an obvious thing, as a drop down generally affords more space than the collapsed control, but still I cannot find an obvious way to do this.
You might want to take a look at http://www.codeproject.com/Articles/37503/Auto-Ellipsis.
It's similar to Zenexar's suggestion, uses a more efficient reduction algorithm in the general case. But it also writes about other types of 'ellipsing', which might also suit your needs perhaps.
Take the selected UIElement. Compare the RenderedWidth and RenderedHeight to the DesiredSize, the latter of which will be adjusted based on how the element is cut off. Repeatedly remove characters, append ellipsis, and invalidate the layout until the DesiredSize is smaller than or equal to the RenderedWidth/RenderedHeight
I think the best way would be to check the length of the selected item. If the length is more than a predetermined character length, cut off the rest and append three periods.
Ok I have the following problem in Silverlight. I have a control with 2 columns. On the left is a stack panel with line numbers and on the right is a textBox.
So when I write in textBox without wrapping turned on I can simply create the right count of numbers on the left, because I'm searching for '\r' in text.
But when I turn on wrapping I have no control over the count of lines in textBox.
Is there a way to get to that count? Or a way to know which line in textBox is going to wrap?
I hope you can understand what I'm trying to do.
There's one way to do this. You can simulate the word wrap operation in the background using a TextBlock. Here is a good link of the complete solution to this problem.
Extended TextBox control with MaxLines property
Is it not possible to create your items in code before they are passed to the view. This would enable you to bind a list of items to a listview and style them as you wish.
You need to user a value converter to count the number of char / lines and then trim that number if you wish to. Unless you use fixed width, you can't really count or calculte in advancet the size, since each application might be displayed differently (due to different sizing option).
There are two great sample chapters on Windows Phone and Silverlight for Windows Phone on the LearningWindosPhone.com site. There is great Windows Phone Trainng material , and dont forget the Windows Phone Develoeprs Blog
Yes there is a way to get the number of lines occupied by the text in the textbox. It's not that simple though 'coz you have to simulate the behavior of the word wrap in order to count/predict the number of lines generated as a result of a word wrap. I have the solution described here in detail.
