Is there a good way to limit the Auto Width of an element or Grid Column?
I want to limit the Auto Width only, but allow any user changes.
For example, I want to allow GridSplitter to arbitrarily resize the column, but the initial (Auto) Width should not exceed a specific value. Same for the elements -- I want to allow resizing, but limit the Width they have if never resized.
MaxWidth works exactly as opposite -- it does not affect Auto Width of Grid Columns (it might be a bug), but limits the resized width.
Is there any good solution that works for (almost) any element or Grid part?
Try binding the MaxWidth to the Width and use a IValueConverter to react to changes from Auto to specific values.
In the grid column set the width you want the column to start at. Any changes to the column width made by the user using the grid splitter will overwrite the width you start with.

I want to autosize the grid columns to max size of the content. How do i do this. i see only autoSize function on grid column, not sure how to use it.Say column header width is more then the column data width, that should be used.
I have used autosize function, It works, but i have few issues, I have to define the align property i.e text fields will be left and number fields will be on right, then heading text gets cut. I have locked columns in all reports, locked section gives some empty spaces.

See column selling code. Its not showing full because of align: Right property. If you remove it will work.
2.After DOW column empty space is coming.
Without minWidth Property columns wont scale properly.
Take a look at this piece of documentation: Ext.grid.column.Column - Setting sizes. I don't think you can make columns scale to content. You can, however, set fixed sizes or make them flex.
I hope this helps.
Is there a way to set the preferred size of a WPF control without setting its maximum size?
I normally set all of my WPF controls to have have automatic height and width, and I set the alignment to stretch. That works great in a lot of cases. My windows come up in a reasonable size by default. If the user stretches the window, the extra space will go where I think it should.
This broke when I set the width of a DataGridTextColumn to "*". Now suddenly the preferred size for my table is several times bigger than my screen! The initial size for my window is exactly the size of my screen.
Of course, I could set the MaxWidth of my table (or my column), but I don't want to do that. The max width was fine at infinity.
I tried changing the Width property to a fixed number of pixels. That seems to change the maximum width. Even though I set HorizontalContentAlignment="Stretch" in the table, the table is centered and the width does not change.
Is there a way around this? I like auto-sizes most of the time. And I like setting the width of a column to "*". Is there a way to make them work together?
It seems like there's a property somewhere that I can't find. At some point the container has to ask my table what size it wants to be. That answer might be ignored or adjusted, but the table had to answer that question. It seems like I should be able to change that value, without changing the max size. (And it seems like if I say "stretch" and there is extra space, my table should be stretched.)
Thank you.
This seems close to some other questions I've seen out here, but not close enough...
I have a grid with three rows. The first row holds a custom grid that I want to have as much space as possible. I set its Height to "*". The second row is a row of buttons; it is "Auto". The third row is a user control that contains another custom grid that has an unpredictable number of rows (none at design-time, filled in at run-time).
If I set the third row to "Auto", it doesn't get any space at all. I need to understand what I have to do after I load the third-row's grid to make it then figure out what "Auto" should be. Or, if "Auto" doesn't apply, how else do I get the third row to take up Just Enough space?
Does my custom grid have to fire something like a resized event after it is loaded?
You shouldn't have to do anything
If the 3rd row's Height is Auto, it will resize according to the size of it's contents. If the size of the contents change at runtime, so will the size of the Row.
You can also set limitations on the Row's Height by setting MinHeight and MaxHeight on the 3rd Row so it doesn't get smaller or larger than a specified height.
Cells will collapse to fit their contents. If the contents don't have any specified size then the cell will collapse to nothing. I'm guessing for your middle row the buttons have fixed sizes, so the row collapses to the size of the buttons, but your third row has nothing with a fixed size so it collapses to nothing. Try giving your third row a fixed size either for the whole row or for each row in the contained grid.
I have a DataGrid with a custom theme. Right now, if I resize a column and make it wider, it tries to squeeze other columns to make space for this column.
Instead, is it possible to increase the width of the entire DataGrid with the increase in width of a column. It's OK if it shows a horizontal scrollbar at the bottom.
EDIT: Just to clarify, each column has a MinWidth set to it. So if the overall width > window width, I see a scrollbar. But in cases where I have a datagrid <= window width, and I expand one of its column, the width of the datagrid should theoritically increase at the point when the other columns have shrunk to their MinWidths. At that point, instead of letting the DataGrid grow in width, it doesn't let me expand the column any further. Instead, I want the DataGrid to expand and accommodate the increased space.
It sounds like one of your columns has a Width="*", which means that column is assigned to all remaining space and grows/shrinks as needed instead of letting the DataGrid grow/shrink as requested and showing it's HorizontalScrollBar.
The datagrid's default behaviour is the one you need! If your Datagrid is not showing a horizontal scrollbar maybe because it's contained in a control that's constraining its width. Try to put it inside a Grid, and be sure that you haven't set the 'Width' property of any control (including the Window) that is containing it.
that's what column's MinWidth is designed for. Just set it for the columns, which you don't want to shrink. to limit the max width of the grid use the ScrollViewer:)
Is it possible to use WinForms layout engine to set up a form in such a way that the height is adjusted completely automatically to fit the content, but the width would be adjustable by the user?
As an example, consider the following somewhat contrived form:
TLP: TableLayoutPanel, with 1 row and 2 columns.
label1: Label, contained in the left column. Set Text to something long, AutoSize to false, Dock to Fill.
button1: Button, contained in the right column. Set AutoSize to true.
Now set the row to "AutoSize", the first column to "100%" and the second column to "AutoSize".
Finally, set the whole TLP to AutoSize true, AutoSizeMode to GrowAndShrink.
At this point, the TLP could reasonably be resized horizontally, but WinForms doesn't seem to allow this.
The idea is that the form containing this TLP would grow or shrink vertically based on the width, which the user can change by resizing the window as usual.
Hopefully you have got the solution by now. But in case anybody having a same query, You can set width of Maximum Size Property to the Actual Width of the Form and the Height of MaximumSize to 0.
This is entirely possible. To do this, you have to override SetBoundsCore on your form. In this you can then control the height such that it doesn't change when a resize might want it to. Just store the height you want it to be in a variable and then have your override always set it to that. This way, when you auto-size the height, you save the new height aware before setting form Height and SetBoundsCore will honour that new height.
