I have a winforms application with a listview that shows 6 items. The problem is that each item's width is too long so the user has to scroll to the right to see all of each item.
How can I shorten the width of each rectangle for each item to match the width of the data inside the item/rectangle???
Thank you
Use this code:
ListviewName.View = View.Details
ListviewName.Columns.Clear()
ListviewName.Columns.Add("Columnn1", CInt(ListviewName.Width / divide))
add all your column.
divide value is depends on how many column in your Listview, but that's if you want all of your column size is equal.
I have used CheckedListBox control in vb.net application.
I have several items as follow, item 1, item 2, item 3........item 100.
Now, i want all these items to arrange into three columns and then appear verticle scrollbar.
But, in CheckedListBox, it appears as horizontally. i want it to appear horizontally for just three columns and then vertical scroll should enable.
Can you please suggest if possible in CheckedListBox control or any other control and if possible then how i would have to set its property to achieve this.
I don't think you can do that in a CheckedListBox....
You could create a FlowLayoutPanel, with a fixed width and add AutoScroll = True.
Then add a number of CheckBox controls to it.
You could have problems regarding column alignment and margins. If that's the case, you can set the checkbox Autosize = False and make them a little larger (in order to contain the text)
Or you can reduce the Height of the checkboxes to reduce spaces (is this what you want?)
eg. Height = 15
Use repeat direction =horizontal and repeat column =3 for checkbox list
I am creating a a report from code in Access. However, after the report is created, the height of the details section seemed to be set to be 3.5 Inches where i really just need it to be a small height.
I've tried researching online and it returns results such as Me.detail.height = 500 or detail.height = 500 and even detail.autoheight = true
At the end of the day, the report generated still had a height of 3.5 Inches. After the report is generated, i am able to shift the bar manually up, so there is definitely no other controls taking up space at the bottom of the details area.
Can anyone enlighten me on this trivial issue? thanks!
You have found the right property to edit, although if it's on report generation you should set it up in design mode and not bother with VBA: the height property should only be changed programatically on the report if you have a button or something where you want to edit things after the report has already generated.
Other things to consider:
The height is in twips, which is 1440 twips per inch, if that gives you an idea of what numbers the height should be.
Secondly, the details section repeats for each record. So, if you have a height of 500 and 10 records you'll end up with a height of 5000 which is roughly 3.5 inches. There is no value which is the combined height of all Detail sections, especially due to group by headers and footers/ totalling etc.
Remember that the Detail section repeats for each record, for me I usually shrink it down to only 1 line tall.
EDIT: to change the detail programatically (assuming you already are using a report object)
reportObject.Section(acDetail).Height
allows you to edit the height of the detail section before the report is even created
I have a Dojo Datagrid which has 10 columns and about 400 records of data... it doesn't seem like that much but it is very very slow to scroll...
I have another Datagrid which has some 5k records and it scrolls faster. The only difference between the two is that for one I am specifying the height in pixels and have autoheight turned off...
For the smaller one, I couldn't use height = 100% to fill up its parent div because for some reason it doesn't like a percent height and doesn't even render the grid if I specify a percent height - I have to give it in pixels... if I use autoheight = true, then it fills up its parent div which is what I want but then it loads ALL data in the grid at once and so it doesn't do any lazy loading of the data.
Any ideas how to achieve lazy loading and still be able to use autoheight = true (or be able to expand the grid so that it always fills up the height of its parent div)?
Thanks
autoHeight can be set to a numeric value, which will define the maximum number of rows to display
I have a rdlc report that conains a tablix, nothing other. The Tablix expands in horizontal direction to show days and in the vertical direction to show groups.
The tablix works as expected, as long as I set the width of the content area equal to the width of the tablix.
If I expand the content size to its fixed size (approximately PageWidth-PageBorders) and run the report, every second page is an empty page.
However the tablix only uses one page. Every odd page is absolutely empty. It seems that the tablix adds its horizontal expansion to the currently definied content width and calculates then the overflow.
The reportviewer Version is 3 (2010 Redistributable)
Does someone have a solution for this odd behaviour?
Update
If I export the report to excel, I see that there is on the right site of the tablix a column that is exactly as long as the generated items for the days. It seems realy to be a bug or a feature I don't see how to deactivate.
I also have tried to create the same construction from a table, and it resulted in the same problem, what not is astonishing, because the table is internally also a tablix.
Update 1
If I set the property "ConsumeContainerWhitespace" of the report to true, the above test version works. But if I place then other elements in the "white" area, the effect reocurrs.
Setting the page-property ConsumeContainerWhitespace=true (in the properties dialog, F4) has helped. However it was anyhow tricky to build the report correct. At the begining it worked only if I added all extra content to the page-header and footer. But this was not acceptable. After a lot of trying, I succeed in making the report as desired. However I don't really understand the logic behind.
I have in mind that I already have done such reports (growing in both directions, horizontally and vertically together) without any problems and I don't know what is difference to this report here. For this report, it's definitively reproducable that the ConsumeContainerWhitespace-property makes the difference. But why this never happens to me for similar reports I have done, I don't know. Also I don't know why I had first to circle around before the layout-engine accepted my design.
The best way to solved this problem is, for example for an A4 page where
Width=21 cm and Height=29.7 cm
Now Margin Left=1 cm and Right=1 cm so you are having a usable width of 19 cm.
When you have understand this basic calculation that means your problem is solved. You can set up the report page size properties by right clicking on the report property => pagesetup.
I was working with an RDLC report that was printing an extra blank page. I tried all the usual tricks, and everything I could think of, until I realized the problem was caused by an extra amount of visible whitespace in the right margin area of the report. One of the objects in the report (a "Rectangle") was a single pixel or two too wide, and this prevented resizing the visible space of the report. Once I removed all the extra width, the report started printing with the expected number of pages.
Visual Studio 2017 (15.7.5) + Microsoft Rdlc Report Designer extension (v14.2)
I had a similar problem, I solved it this way
For instance for width, the following equation should be satisfied
PageSize >= LeftMargin + BodySize + RightMargin
where to find BodySize?
Press F4 -> CLick somewhere inside the report -> you will find body property(look at size property, take the width value)
Where to find report PageSize?
click somewhere outside the report -> you will find report property ( look at PageSize (take its width value), and margins (Left, right, ..), take left and right margin values)
take values from these properties, and check if they meet
PageSize >= LeftMargin + BodySize + RightMargin
Check the "body" size, try to make it as wide and height as your real paper size but reduce only the margins.
There is a confusion there on the page design. Developers would think the report being designed is WYSIWYG, but actually it's NOT!! Microsoft reportviewer will take your designed page as the content!! and append the margins defined on the outside of your page, and turn out that your page can never fit in to one page!!
So, when you design a new report, focus on the content area, the client area, including your headers and footers, and allow margins to be appended on your outer border.
the solution is simple ConsumeContainerWhiteSpace=True (you find this in the property window for "report") you set the paper size in the main menu/ report/report properties for example to "A4" and then you check that paper size is larger then body + header + footer + margins.
I was having the same issue until I played with the report body's height and width. :)
Please select "Report" in the object selector at the top of the window.
and make the ConsumeContainerWhiteSpace = true
if the also same problem persist then, your rdlc report size should be less than your report body.!
I have meet this problem recently.
The root cause may be:
your report's body has some blank upside report Footer or somewhere else.
The solution is :
1, click the report body
2, go to the property window, you will see the body size property
3, check the body size, you may find a strange number like 9.6654in,1.5625in.
that means you have some blank upside the Footer, modify the height or width size till there is no blank you can see.
Go to Property F4
Select Body
Write width and height to 1cm
Visual studio will overwrite to the smallest Body possible
Done.
You need set report width property to actual print page width. In my case 6 inches helped.
You need to make sure your RDLC Report have :
ConsumeContainerWhiteSpace = true (open by click F4)
Report Body Size <= Page Size+margin Size. (open by Ctrl + Alt + D)
Page Footer may cause the problem too. So if you have one, it's better to place it as near as possible to the main content. In this case you don't need to set the Body.Height property.
My 4x2 inch label was printing 3 extra pages for a one page report.
To fix it, I reduced the Body.Size attribute to be same or smaller than the Report.PageSize minus the summed respective Report.Margins.
Try this one,
Just make sure that all Data the needed is in the report,
Then Select the Table or the Matrix and make it squeeze to the left and if needed to the Top Left Corner until your white Page Problem is Done.
But make sure that the cells are squeezed in the right manner, Be gentle (I hope you got it !!)
Ok, Bye
Or you can just graphically resize your report design, to the exact bottom of the last report control or label.
Or add a footer section to create some space.
I thought this important enough to put here, especially since every day more of the critical information we need to do our jobs keeps disappearing:
From response to The "Every Other Page Is Blank" Feature
Many Reporting Services users ask this question:
"I'm rendering to a physical page format (PDF, Image, Print) and for
some reason a blank page gets inserted between all of the other pages
in the report. Thank you, Reporting Services, for the free pages.
It's a charming feature, but paper ain't free and I'm getting paper
cuts pulling out every other blank page after it's printed. How do I
make it stop?!"
To which I reply:
This is almost always caused by the Body of your report being too wide
for your page. Make sure that the Width of the Body is less than the
physical page size, less the margins. For those of you who are into
the math thing, make sure that:
Body Width <= Page Width - (Left Margin + Right Margin)
For physical page renderers, it's important to keep in mind the
concept of Usable Area. The Usable Area is the amount of space left
on a page for your report to be drawn after reserving space for
margins, headers and footers, and column spacing (for multi-column
reports).
Horizontal usable area:
X = Page.Width - (Left Margin + Right Margin + Column Spacing)
Vertical usable area:
Y = Page.Height - (Top Margin + Bottom Margin + Header Height + Footer
Height)
Any time objects on your report (including the Body itself) extend
past the usable area either because they are defined like that or
because they grow at runtime, the physical page renderers have no
choice but to break onto a new page.
Make sure Body size is cm , not in(inch)
For me when I increase the width for pagesize report from 21 to 23 cm , It was not generating extra empty page.
Because of few elements total size of my report's element was greater than 21 and less than 23, that is why I changed to 23cm and works for me.
In my case I have only one page and I was working with .rdl file.
