I have a grid containing rows flagged with different priorities. I want to color the high priority rows red, low ones blue, etc. I'd like to set the shade based on a mathmatically calculated gradient rather than arbitrarily assigning colors to specific priorities. How can I extract a single color from a single point along gradient?

View 1 RepliesI have written general module to transfer the grid values into respective textbox. For that I pass Listview control of form & parent control ( e. g. groupbox ) of textbox.
The module loop trrough each column of grid & store the value in respected textbox ( the textbox names are identical as that of grid column) It works fine, but when I pass tabcontrol it does not work
This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

how to cambine 2 data grid view into 1 data grid view
View 2 RepliesWhat would be the most efficient way to find the grid a collection is bound to. Is there a way to use databinding to return the control a collection is bound to? I need a method like GetBoundGrid(myCollection) that returns a datagridview.
This method will be on our EntryFormBase form. This is a 3 panel form consisting of a search area, search results (MainGrid) and a detail section. This base forms handles all the logic for adding, saving and deleting data. (Bad design I know but it's what I inherited.) If I know the current collection I need to determine the grid it is bound to.The app I am currently working on was created using VS2003 before binding sources were available so it is bound old school.
I am having a pplication, where I need to send EMail to multiple persons one after the other, what I need to show is the Grid which is populated with the PersonName,EMailProgressBar, Status. I am using the DevExpressGrid so I had been able to bind grids with these three items and as an ColumnEditControl for the EmailProgress I had assigned Progressbar. But now what I am not able to do is show the Progress in grid one after the other as emails are being sent. I mean when the first email is sent the progressbar in first row should be active and as soon as second email is started it should showing progress for secod row of grid. I know it is easy said then done but I hope that there are some experts out there which may have done something similar in past or have some ideas.
View 2 RepliesI am designing a yahtzee game in Visual Basic. I am wanting to save the form's background color and the picture boxes dice so they can be set the next time the form is loaded. The user can change the background color of the form and choose between several sets of dice. I want the last color the form's background color was and the picture of the last set of dice used placed back in the picture boxes of the dice the next time the user opens the Yahtzee game. I am trying to do this in a module, with generic collections of all the picture boxes on the form. Am I able to do this before the form loads?

View 1 RepliesI have to design a custom "log grid" control to use in another of my projects.Up front, I am new to vb.net 2008. I have used VB6 for years and I am trying to learn how to resove the differences as I go. But I need help.
This log grid contains 96 columns and 4 rows.I tried using the TableLayoutPanel and a Panel per cell but found the control to slow to paint. That's 384 discreet controls.I am now trying a usercontrol with a panel and GDI+ to create the grid. I've created a collection for the columns and a collection for the rows. So far so good. My mouse clicks raise the correct events per cell.
I now need to indicate which column the mouse is over. This is the problem. The column must be highlighted by a vertical bar from the top of the column to the bottom. It must also be transparent. I need to see the gridlines under the highlight. I've tried using region using the following code. (myRegion is declared Private MyRegion as Region at module level for persistance)

Are there any good free alternatives to DevExpress data grids (WinForms)?I am looking for WinForms Data Grid and Data Editor Controls.
