I need to get the DataGridView to perform the way it should perform. I'm new to the .NET environment, but I learn fairly quickly. However, I find it difficult to decipher themassive black box of the DataGridView control enough to make it do anything other than what it already does--Draw very slowly.
View 3 RepliesI have a VB app which draws primitive shapes (lines, filled rectangles etc.) into a picturebox control (from its paint event). I've since found out that a picturebox is probably the worst control to use for this. I've also found out that it's better to draw directly onto the form but I don't really want to do this as a control gives clipping for 'free'.
What would be the best control for this? The panel control looks like a good candidate but the experiment I tried actually performed worse
I have a form that uses a button to draw a line and a second button to draw a rectangle. I have a third button to clear the form but can't find a code example to code the Clear button.

On Form1 we have: TextBox1 TreeView1 - holds list of customers, is located near the bottom of the form, not visible from the start. Now, when I start typing text in TextBox1 (i need to filter customers), TreeView1 appears and suggest for example 30 customers matching the searched text. I want the program to show the treeview and draw it also outside of the Form1 boundaries.
View 7 RepliesI have an application that uses DataGridView in two different locations. In one location, the DataGridView shows everything fine. In the other location, whenever the form containing the DataGridView is initially loaded, only about half of the visible portion of the DataGridView is actually drawn; through the rest of the DataGridView, the underlying windows graphics can be seen; if you scroll down through the rest of the data, you get a choppy view of what corresponds to the bottom row being scrolled upward through each scrolled row. The only ways to get the DataGridView to show the correct values are either to select a cell, forcing that particular cell to redraw; or to invalidate an area of the window, causing that area to redraw (which it does do correctly).
I've compared how each of these DataGridViews were set up: For the one that works fine, the DataGridView is statically bound to a BindingSource, which is statically bound to a DataSet; the one that has the draw problem is statically bound to a Binding Source that is dynamically bound to a DataTable during the creation of the form.
What could be causing my DataGridView to not display correctly?
I treid this code to draw the cells value of DataGridView on the form. but it display the three cells in the same place means: if the cells including A-B-C it didn't showed them like this : A B C

I have a borderless form that I'm "docking" onto the top edge of my screen. Inside of the form, I'm placing a single toolstrip control, which docks across the entire form -> (picture the taskbar to get an idea of what I'm talking about).Because the borderless form has no edge to it, I wanted to draw a black line along the bottom edg` of the form to differentiate the form from the windows or desktop behind it.
The problem that I'm facing is that`the toolstrip will not move "behind" the line when it's docked, no matter how I order the control layers.
I've tried programatically sending the control to back to no avail either.
Any ideas on how to get the line to show above the docked toolstrip?

I have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.
View 4 RepliesI have a DataGridview. The user has to pick an option in the datagridview. I am contemplating either putting a context menu in the DGV. I am assuming that I will fire my context menu on the Cell Enter event. However prior to that I need to draw the users attention to the column of interest.
I know I can hide all other columns but his is not userful as they need to be visible. I am also assuming that I can highlight the column in the form load event. Or I could use some sort of Call Out box in the form load event that draws the user to the column. Can you create a call out box from a context menu?
I've got a usercontrol that's a simple rectangle with three labels on it. It's essentially triggered to give a caption to an image when the mouse is moved over it. As I feared, adding the control to the form (or any container on the form) restricts drawing the control to the region defined by the container. I tried increasing the region of the form and the container, but it still didn't draw outside the container.
So my question is: Is there a way to make the control display partially inside the container/form and partially outside it, or is there a better object type that will do what I want?

Im looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,

View 5 RepliesI'm looking to draw a trackbar normal, only with a transparent background. I have created a new class that supports transparent backgrounds set to true. Without using userpaint, the trackbar does nothing or takes the color of it's parent. When using userpaint I have to draw the control on mine own. Not quite sure where to start first though...
I've read about drawing a line (not so hard), drawing a floating object (to act as marker), and handling events on when the floating object moves left/right... Drawing 3 separate objects inside an inherited trackbar control seems like a clunky way of calling methods that should exist somewhere? Is there an easier way to draw the control normal without a background? If not, some in starting to implement all 3 new objects working together would be good (I could draw them separately but that's about it).
Everywhere in this picture you see a blank item, or empty space, a control has failed to draw of something. In this case they are all textboxes.

View 1 RepliesI have spent the past week trying to get my copy of Visual Studio 2010 Professional to work on my Windows 7 Professional 64-bit laptop, with no avail.
Every time I try to create a new form using Visual Basic, an error message saying that Microsoft Resource File To COFF Object Conversion Utility has stopped working, and I cannot even run the new form to see if my coding is correct.
I have managed to find that it has something to do with the cvtres.exe file, but after a solid hour of research, I have found numerous others with a similar problem, but no solutions.
I have done registry scans, reinstalled Visual Studio about 3 times and have done many other suggested fixes that have done nothing but waste my time.
