can anyone please let me know is it possible to show error provider icon on listview.
ie if Im having a listview of items.. I would like to show error icon on a specific item in a row.
Typically you'd solve this problem by changing the icon to an error (red circle with white cross) and adding a tooltip to the ListViewItem.
if you want to use your images in the listview use ImageList class and bind it to the listview via SetImagelist method.
You can try a freeware WinForms component Better ListView Express. It allows displaying images of arbitrary size in both items and sub-items. You can also draw your own graphics with powerful owner drawing.
For example, all items can be shifted and you can display the ErrorProvider icon next to the items, or after them. Overlay is also possible.

I have a listview box which contains my data, it is loaded when selected into a infragistics data chart, it is all loaded into a single stacked bar series. What I now need to be able to do is click one segment of the bar series and be able to highlight and zoom in.
Does anyone have any advice?
Thanks in advance.
I suppose you are using Bar/ColumnSeries to display single stacked bars.
To highlight you can make use of ChartAnnotationLayers to highlight a particular value & hence the bar by setting the MarkerTemplate property.
Also you can set a default value or override it on hover.
The documentation here can help.
I have developed a winform application. It has a listview with multiple columns having different texts. Initially, I have set the column width = -2 to take the size of longest text in the column.
The issue is that sometime text overshoots the laptop screen and a horizontal scroll bar appeared in the list view.
To fit all the columns in a screen, I manually modified the columns widths using column boundaries in the GUI. When I modify the column width, the column text starts disappearing from right. I want it to disappeared from left.
I have searched goggle a lot but did not find the answer.
Question might look weird or may be I have not explained it properly. Please let me know if more information is needed.
Thanks in advance.
The Listbox columns in Windows Forms are not exactly a high level control, I've used it some times but just for simple lists, It certainly has not a builtin function to make what you want, to obtain it you probably need to subclass the control, create a new class for the item managed in the list and write some code to perform what you need.
I think you can find some hints on how to achieve all this in Charles Petzold book about windows forms where he shows how to measure a string and how to draw directly on your control.
We need to show our disabled comboboxes as an image. The image has the same height as the standard combobox, but for some reason it cannot override the borders of the combobox.
Instead, it end up looking like this:
We would like them look like this image, i.e. that the image is shown on top of everything - including the combobox borders:
Any ideas?
Thanks.
First of all, what you are trying sounds really dirty - the best way would be, if your ComboBox would just look like your image as soon as you disable it!
If there is really no other way:
Create a PictureBox in front of your ComboBox. Set the image as the PictureBox's image, make it Visible whenever you want to "disable" your ComboBox.
But again, using controls to simulate behaviour you would expect to be part of another control is dirty.
Get the location of you textbox, set it invisible, then a the same location place an imagebox

I have a Listbox ,with some items added to it.My problem is i want to draw an image in the left side of each and every items in the listbox.Can anyone suggest any idea?
Thanks in advance.
I can do this by using ImageList.
imageList.Draw(ea.Graphics, bounds.Left, bounds.Top,item.ImageIndex);
but i want to use like this
ea.Graphics.DrawImage("someImage",new point);
You should use a listview control not a listbox for this. The listview natively supports imagelist binding and listviewitem has imageindex property so that you can specify the index of the image to render from the imagelist.
Probable approach -
You can have "List item" composed of UI control with image or drawing area (depends on your requirement). This way you should be able to draw.

I am drawing rectangles inside a picture box, based on data that is being pulled from database. Everything works correctly, now my question is, is that possible to select created rectangles? I'd like to be able to select the rectangle and change the data in it.
I guess one of the options will be to along with rectangles display the list of them, and select them from there.
If anyone has any experience with this, I would greatly appreciate a tip.
Thank you,
H
You could, instead of adding directly a rectangle to the form picture box, create a custom windows forms control that holds a rectangle, and add it to the form directly, or to some kind of container.
There you can easily handle the click event of your custom control.
Look here for help on how to do this.
