I'm putting together a simple winforms app, which consists on 1 form and a textbox.
I want to have the textbox scale in width when the form is scaled by the user.
By default the textbox is a fixed width and anchored at the top & left. The form scales ok, but not the textbox.
If I apply left, top & right anchor to the textbox it only scales the textbox & form up and I can't shrink it.
Do I need to dynamically set the width of the textbox to that of the form?
I've been trying to recreate this for 5 minutes and it resizes fine for me, and I've only been able to find one set of combinations that reproduces the behavior you describe:
Is the textbox inside a panel with Autosize set to "true" and AutoSizeMode set to "grow only" perhaps? That's the only way I've been able to duplicate the behavior.
Here's a screenshot of the properties set this way. My textbox is also set to anchor at top, left, right. Again, this is the ONLY way I've been able to duplicate the behavior you're describing, so hopefully this helps.

In this WinForms-App (not my choice, they made me use WinForms) there is a FlowLayoutPanel filled with a NumericTextBox, a Label and a CheckBox.
Each control has a text which is displayed. The text of the Label is about 3 pt lower than the other texts (image).
Changing the margin of the Label is not an option, because the outcome after changing the font could be unwanted.
Has anyone an idea of how to fix this without changing the margin?
I tried to change the anchoring and docking for the controls in the FlowLayoutPanel, and the outcome that came closest to my expectations was the one in the image.
I'm a developer who's trying to get the hang of Blend. I've always used Blend to mess with control templates and such, but I'm trying to get the hang of using it for basic UI design, since I figure it's probably a bit faster than typing the XAML up manually in Visual Studio.
Right now I'm just trying to create a basic Grid, but I'm seeing two default behaviors that I'm hoping someone can show me how to change.
1) When I hover my mouse outside of the design surface, I see the temporary yellow line to show up, where the new Grid Column / Row will be when I click. The problem is that the newly created rows are set to heights like 0.2297* How do I get Blend to attach regular heights, like 250?
2) Ignoring 1), once I have some rows and columns, when I drag a button, or combo box, etc, onto one of the cells, it drops it exactly where I release the mouse, while adding some large margins to position it there. Is it possible to tell blend to just drop the control into the cell, and leave the margins alone?
Grids are awesome but it takes a bit of play to get proficient at working with them in Blend. Here are some tips to get you started (I cover this in detail in chapter 4 of my book).
1) When you use the snap lines to create rows and columns Blend automatically makes them relative (Star) sized, which is the behavior you are seeing. To change the row/column style to fixed (Pixel) sizes, click on the Padlock icons to the left and top of the desired rows and columns. Then, either edit the values in XAML or you can click near (but not on) the padlock to select the row or column. This will open the sizing properties in the Properties panel.
2) The short answer is "No". Blend will always add Margins when you draw the element in a cell unless you take care to draw them to the borders. This is too difficult and time consuming, so I just make sure I draw it somewhere inside my target cell. Now I can right-click the element and select "Auto Size > Fill" and the element will fill up the cell: no Margins, Width and Height set to Auto, and Horizontal and Vertical Alignments set to Stretch. [FWIW, addressing this is my number one feature request for Blend.]
I hope this helps.
To answer point 1) Blend is creating proportional grids so that the columns remain the same relative widths when you grow or shrink the grid rather than absolute grids. So if you want absolute grid widths you'll have to go in and edit the values by hand.
I find that it's easier to create the basic form in Blend and then tweak the values in the text editor - either in Visual Studio or Blend itself.
As for point 2) I've just tried this and as long as I click inside the column/row on the grid when placing a button it adds it to the correct column/row of the grid as expected. Select the button and then just double click inside the grid - this should add a button of default size where you clicked, but in the grid. (It would be much easier if I could see what you were doing).
I have a simple dialog with tab control whit property Dock = Fill. On the tab page I add another control and set its properties Anchor as 'Left, Top, Right' and min size as '600,300' for example. I set the property of tab page AutoScrolling to true.
But when I resize the dialog the horizontal scrolling of the tab page doesn't work when the dialog width is smaller than min width of the chield control.
Why horizontal scrolling doesn't work in this case? Is it bug or maybe feature?
Thanks a lot!
I can't even get the scrollbar to show up. Right/bottom anchors don't work well when auto-sizing layout. Set the AutoScrollMinSize property to an appropriate value, that also ensures you've got enough margin to the right of the button.
It's because of the Anchor. You anchored it on the left and right which means that it will have no minimum width, its width is determined by its container's size.
What is the effect you're trying to achive?
I currently have a Textbox on a Windows Forms, and I need to dynamically add a PictureBox box control at the right of the Textbox.
I create the PictureBox programmatically and I when setting the location of the PictureBox, i'm setting like this:
pBox.Location = new Point(tbControl.Location.X + ctrl.Width, ctrl.Location.Y);
So i'm setting the picture box to be located at the X location of the textbox PLUS the width of the textbox. However, since the textbox has an anchor property set to right, its width increases to fill the space between itself and the form border.
Problem is, that even though the textbox's width is visually bigger than the actual value of Textbox.Width. the Width property is not taking into account the extra width of being anchored.
I already tried properties like Textbox.Bounds.Width, Textbox.ClientSize.Width, Textbox.DisplayRectangle.Width, etc. with no luck. All of those properties return the original Width of the control without taking into account the resized width due to the Anchor property.
Does anyone know how I can determine the real size of the textbox? Thank you
The Width property always tracks the current width of a control, whether it is anchored or not. However, the TextBox is going to grow when you make the container larger and that will make it overlap the PictureBox. You have to anchor the PB to the right as well.
These should be returning the adjusted size. Either you are referring to the wrong textbox, or you are doing the query before the size has actually changed.
I have a dialog with column down the right side filled with buttons. The dialog is built with Windows Forms. I have a mockup at the following link:original dialog
(I would have included it but apparently i'm not allowed to use image tags)
I would like for the buttons in the right column to resize themselves to fill the remaining vertical space when the dialog resizes. It doesn't particularly matter to me whether or not buttons simply increase in size or whether the buttons remain the same size while the gaps between them increase. I'm simply want the buttons to go from the top to the bottom. (I have a mockup for this as well but apparenlty i can only include one link)
I've tried hosting the buttons in a FlowLayoutPanel but they do not increase as the dialog stretches, I only get whitespace at the bottom after I run out of buttons. I also tried a TableLayoutPanel and had the same result but I may have misused it. Does anyone have any ideas how I could accomplish this?
Thanks in advance,
Jeremy
To get you started. Use the TableLayoutPanel, set its Anchor property to top, bottom, left, and right. Set the rows and columns to percentages as needed. I suggest each control have it own cell. Note that each control in a "cell" can have its Dock and Anchor property set as needed.
You can do this with a TableLayoutPanel. Create a column for the buttons, with each button having it's own row / cell in the column. Set each row to be an even percentage for height (if there are 10 buttons, each row would be 10%), and dock the TableLayoutPanel to the right side of the screen. Then, put the buttons into their rows and set them to full docking. Then, when the dialog expands, the TableLayoutPanel will expand to fill the entire right side of the screen, each row will adjust proportionally, and each button would expand to fit the new row size.
You may have to adjust this a bit to fit your needs, especially in how it relates to the other content in the window.
