Can anyone help with this simple question.
I have a c# ListView. It's the only control on the form. The View property is set to details. When I resize the form I programmatically resize the ListView to fill the whole form.
Problem is, when the form width gets too small to show the lines of text in the ListView it wraps each onto more lines of text - I can just see the top of the characters of the second line.
Thing is, I would rather only have one line per item and the user would have to use the mouse to horizontally scroll the "too long" items - just like in an edit box when the text is too long.
Thanks for any help,
Mitch.

Using UWP XAML, I am trying to recreate this textbox UX from Postman whereby it pops up above all other elements in the app to display the full text: https://streamable.com/avrixo. I've almost fully recreated this UX, but I am having trouble bringing the textbox to the "front" of the app while the textbox is inside a listview.
What I have tried:
I have tried creating a UserControl for a custom text box with Canvas as its parent. Like this:
<Canvas>
<TextBox/>
</Canvas
I added some event handling to change the text wrapping and the Canvas.Zindex attached property of the textbox when the user focuses on it (I've tried setting the z-index to 1, 10, 100, and 1000000). However, I found that as the textbox expands vertically, it remains "behind" the listview item below it no matter what z-index I give it.
How can I bring the textbox inside a listview item to the "front" of the UI?
I don't think your problem is with z-index (per say) in this case. The problem here in the ListView is that each ListViewItem has it's own bounds, so the TextBox is being clipped by the bounding box of the item. You can double-check the bounding areas with the Visual Tree tools at least to confirm that's the issue.
If you don't want the ListViewItem to expand in size to match, I can see two options. When the user clicks to edit, you put a 'fake' TextBox (bound to the original in the ListView or the data item) either in 1) a Pop-up that you display or 2) in an overlay that's part of your page's XAML that has the textbox.
You can grab the selection state and cursor positions and such from the original textbox, and move focus to the new one and mirror that same state.
That's the approach I think I'd take.
I'm adding buttons (with text and images) to a richtextbox control, but because I don't use the following line:
richTextBox1.AppendText(Environment.NewLine + str);
The scroll bar doesn't match the total number of lines, and doesn't resize properly, how can I solve it?
What is going wrong
I find this to be a very peculiar way of doing things. So first, lets add a little background:
When you use richTextBox1.Controls.Add(new button()) - what you are doing is: you are adding the new button as a child of the richtextbox, not as content - and this is the problem.
The scrollbars are set to read their height/scrollable area etc from the content of the richtextbox, and yours has no content, hence no scrollbar (or false readings etc).
You could create a custom richtextbox control that inherits its scrollable area from the location of its child controls. However, if you would rather avoid that route, please continue reading:
The correct way
I do not know your use case, so this may not work, but I would remove the richtextbox control and instead use a panel control. The panel control for example will update it's scrollbars based on child controls, whereas the richtextbox wont - and this should give you the behaviour you are expecting.
Here's a screen shot of the problem:
As you can see the left-most part of the string is getting truncated. This is just a standard combobox and there's nothing overlapping it on the form.
Your label is too long!
its overwriting the edge of that edit box.
Bring the combobox to the front. It seems like the label before your combobox is in front of it.
Just reproduced this.
As previous comments suggest, your label is most definitely too long.
Please reconsider the placement of your elements, perhaps the label should end with more space between the label and the combobox.
This can easily be done via the designer window (Shift + F7 whilst on the code behind e.g. form.cs)
Hi i am working in Silver light I ran into an issue where I had more tab items than could fit within the desired width of my tab control. Instead of all the tab items appearing on a single line, they would wrap and create a multiline affect which I did not want.
1. I wanted the user to be able to scroll through the tab items
Can you all help with this? please correct my direction and with sample code.
I have created a texteditor along with a function window.
the functionwindow is a listbox that is populated with all of the functions located in the textbox.
when the user double clicks on an item in the listbox, the textbox will find the function that was clicked on. its just using a simple search to find the text. the issue is that if the text is at the bottom of the window, then you still need to scroll to display it properly. is there a way to ... If line 200 of a textbox was located at the bottom of the screen to make it show at the top??? does this make any sense to anybody
Is it the ScrollToCaret function you want?
