How can I resize a windows form without hiding controls that are positioned outside the form's new size?
Check out the .Anchor property of the buttons you want to avoid hiding. The anchor property can be set such that the placment of the buttons is alwas relative to one or more edges of the form. This way, when the form is resized, the buttons location is "anchored" to (for example) the Bottom and right edges of the form.
This will not prevent the user from making the form smaller than the minimum space required by the buttons, but I believe you can also set a minimum size property for the form.
set the anchor property of your buttons or items in form.
If still you have issues, put the buttons or controls to pannel or groupbox and dock the buttons to parent container. Then apply anchor property for controller.
I Have found the similar issue and what i tried is to put all the buttons in a TableLayoutPanel and set the Anchor property of the buttons that way i am able to resize the button corresponding to the size of the form.
If any body has a better idea kindly suggest........

OK, this is driving me a bit nuts at this point. Time to ask the crowd:
I have a form that consists of: two vertical "halves" created by a SplitContainer. Inside the bottom "half" / SplitContainer panel... I have:
A set of fields/controls for the user to fill out, contained within a panel.
Below that, a panel containing buttons for "submit", "cancel"...and one that's "show/hide". This "show/hide" is intended to show/hide the panel I just described in point 1 above.
What I want to happen is: when the user clicks to "hide" the panel of controls, not only do those controls vanish, but also:
The panel containing the submit, cancel and show/hide buttons moves up (so that we don't have this big blank space where the now-hidden panel once was).
The form resizes itself vertically so as to make up for the now-hidden panel and the fact that we've moved the bottom controls upwards.
I have no problem getting the panel of controls/fields to show/hide. But I can't seem to figure out how to accomplish the other two tasks. I've tried various combinations of AutoSize, AutoSizeMode, and Dock options.
Any suggestions?
If you put all your controls into a FlowLayoutPanel where the children are arranged vertically, then hiding some controls should cause the "lower" controls to move up the page.
You might still need to write some code to resize the form itself once the optional content has been hidden or before it's shown.
I have a windows form which have a lot of controls in
that(Listbox,Groupbox,Combobox,TextBox,ListBox etc). I need to resize
and arrange the controls automatically whenever the form's size gets
changed. I need to know the difference between Dock and Anchor to
implement this. What is the actual difference between Docking and
Anchoring?
The Anchor and Dock properties of a form are two separate properties.
Anchor refers to the position a control has relative to the edges of the form. A textbox, for example, that is anchored to the left edge of a form will stay in the same position as the form is resized.
Docking refers to how much space you want the control to take up on the form. If you dock a control to the left of the form, it will stretch itself to the height of the form, but its width will stay the same.
This EXAMPLE can help you understand a bit more.
A Windows Form application displays a main form. This main form contains few different Panel controls. Depending on some condition in that form one of these Panel controls is to be made active while the others are made invisible.
First panel contains a DataGridview, Second panel contains controls to display the details of the DataGridView. On Add button click (or) On selecting a record in DataGridView the second panel should be visible. I am using Visible property to show and hide panel, but the gap is showing there as shown in screenshot.
Please suggest best way to handle this.
You just need the panels to share the same location. You probably don't want to do that at design-time, as it makes future maintenance of the form difficult.
In the Form.Load event, set the location of the bottom panel to match the location of the top panel.
PanelDetails.Location = PanelDataGrid.Location;
Now when you hide one and show the other, they'll appear in the same place.
The smartest way is to keep the panels separate at the designer. This way any editings made on them can be done more easily, and all actual objects can be seen immediately.
In the designer, set the other panels' Visible properties to False, excep the first one on the top.
Form.Load:
Set all the other panels' locations to match the location of the first panel (on the top)
Set the form's height to match a desired height, which fits to your heightest panel
Use the buttons to toggle panels visibility (and possibly the form height too)
how to resize a tab control in a winform (C# .Net), controls(inside tabpage) must move while resizing the form
maybe the Dock property is what you're looking for.
If you put a panel.Dock=Dock.Fill then it will take all the space available.
so when the controls is resized, the panel is too.
Going off of your comment to Andrzej's answer:
the control's size must be unchanged and move one below the other while resizing the form
It sounds like what you need is a FlowLayoutPanel. Drop one onto your TabPage, set its FlowDirection property to the value of your choice, and place your controls into it. Now, whenever the TabControl is resized, the controls it contains will automatically shift positions to fill the space.
Set Anchor property of that control. Alternatively you may use Dock
Anchor - defines a constant space between one or more edges of it's container.
Dock - control borders are docked to its parent control.
I'm not sure what it's called in the land of WinForms, but in web development terms, I'm looking for a frame type element that can be added to a winform.
I want a panel that is anchored top,bottom,left,right but if the form the panel is resized to a smaller size than the elements in the panel, scroll bars will appear around the panel allowing the user to see the contents of the panel without expanding the form.
I hope that makes sense, and that such a thing exists.
Thanks!
Yes, a Panel control. Set AutoScrollMinSize to the minimum size you want before scrollbars appear. Set AutoScroll to True. Set MinimumSize if necessary, it shouldn't be.
The controls inside the panel need to auto layout by themselves so they'll move as necessary when the panel gets smaller. Use their Dock or Anchor properties. If the layout gets complicated then switch to a TableLayoutPanel or FlowLayoutPanel control.
What about a panel? System.Windows.Forms.Panel
You are looking for a "Panel" control. Just set the "Dock" property to get docking going..
You add a Panel to your form and set Panel.Dock = Fill. Your Panel will auto-resize when you resize the form.
Set Panel.AutoScroll = True
Then, you add controls to your Panel. Set the controls' Dock property accordingly. Now, when you resize the form, scrollbars will appear if controls are covered up.
There are a couple of different panels in the standard windows controls that do what you want... just look in the toolbox when editing a windows form, under 'container'
What do you want it to contain? A web page, or just windows form controls?
