'True' Control Transparency - Control With Motion Graphics (simplicity, A 'video Player' Control)
Dec 29, 2010Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

Disable DataGridView Control?
Mar 30, 2010I have a dialog that gets called from time to time. It is only created once, and then shown or hidden. Depending on the current conditions, when I display it, I need to disable the controls on it so that the user does not make any changes.I have code that checks the condition and sets the enabled property to false for the controls. There is a DataGridView control on the dialog, and for some reason, it stays enabled and allows changes. Does anyone know why, or what I need to do to get it to not accept any input?

View 1 RepliesUse Custom Control In A Datagridview?
Aug 5, 2009I've been working with this for a while now and have finally come to you for help. I have a custom control that inherits from a label and I'm trying to use it in a datagridview. I have followed this example and have tried to adapt it to my needs.
The custom control in this case is a label with a boolean type property named Value. When value is true, the label.text = "ON" and the color is red. When value is false, the label.text = "off" and the color is transparent. This is the effect I need to show in the dgv.
I have attached my developing project and would like you to take a look if you can. The project has a single form with the dgv, the custom control and a button on it. When the button is clicked the value of the custom control toggles. The control on the form changes color and text as it should, but the cell in the dvg simple changes text from FALSE to TRUE.

View 2 RepliesAdd A Summary Row To An Unbound Datagridview Control?
Sep 7, 2011I have an unbound datagrid control I am using to store inspection information. The program records the information from the user, validates the values, and saves it into a database. It will then show the last inspection data in the datagridview. The user has the option of doublclicking a row and changing values and resaving the row. The number of rows per piece inspected varies, so that is why I used the grid to show the inspection data, however, they want to see a running total of each inspection point at the bottom of the grid so when they add the new values, it will update the running totals. I can see how to add a new column for a running total, but the layout requires the sums to be in the last row of the grid. I can add the row to the grid, but I need to make sure it stays at the bottom of the grid when I add a new row, and if possible freeze the row so it is always visible like excel. The program we are re-writting is excel based so this functionality is critical for the inspector to see the running totals for each inspection point.

Can Datagridview Rows Fit Control Without Resizing

View 2 RepliesControl Array Of Datagridview Objects?
Oct 13, 2011Migrating from VB6, a control array of flexgrid objects. Obviously flexgrid is not supported by VB.NET, so DataGridView objects have to be used instead. I tried this alternative to placing them in a list.
I have two DataGridView objects which share a lot of code as well as event handlers. They are named D1 and D2 and many properties, such as column headeders etc., are set at define time. The control array is simulated by passing the "index" and selected grid as parameters in subroutines. For example, the routine to fill the grids, is as follows.

View 6 RepliesDataGridView Properties Through User Control?
Sep 20, 2011I've built a custom user control in VS2010, incorporating two datagridviews, and asplitpanel - The idea is that there is a "Main" datagridview control, and the second is an internally controlled grid that (when shown) displays the Columns which are set as invisible. This allows the user to drag the columns onto the main grid, in order to display the columns.This all works fairly well. I've set the modifiers property on the Main DataGridView to public, so that by and large, the developers can make use of the control just like a normal DGV (albeit with an extra level to the code).
I've also created dummy events for each of the events that the DGV normally raises, and pass them through the usercontrol, so that the developers can attach to the DGV events as normal. Again, this appears to work fine.Unfortunately, I've run into a problem. I'm trying to set the RowSizeMode to DisplayedCells (or indeed any value). If I try it in the designer, it appears to retain the change until I run the application, after which the property reverts back to normal.

View 3 RepliesHow To Create Timesheet Using DataGridView Control
Mar 17, 2011I am creating a timesheet using a datagridview control, the user must enter the time in the cells for the code to process. The control however converts the data to a string even though the defaultcellstyle.format is "t" for shorttime. I need to get the control to accept time in various formats and covert it to a standard format. If the user enters 8.00 the cell should display 8:00 am, if the user enters 8p the cell should display 8:00 pm.
After entering the data the user clicks a button to process the data, the code checks each entry to ensure it is a date (using IsDate) and performs some calculations based on the times entered by the user. the information is then stored in a table. My problem is the datagridview control converts the cell entries to strings but I need it to retain the datetime format as I get a casting error when I try to use cdate to convert back to date.
IDE :: DataGridView Control Properties Have Disappeared?
Sep 21, 2009Greetings. I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.
Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.
I tried a repair re-installation. The same things happens.
I can set properties etc. programatically, but that sorta defeats the point of an IDE, not so?
