I am using the following code to change my backcolor before I print the page.Is there a way to restor the controls to the orginal backcolor they were before I changed them, the reason I ask is not all of them are the default systemcolors.control, so instead of coding each one individually i was hoping for some kind of "REstore" code?[code]....
View 9 RepliesI have a DataGridViewImageColumn that should display an image for only certain rows. After I bind a generic list of classes to my datagrid, I loop through each row and update the image cell with an image that is an embedded resource for the rows that require the image. This works great if the form has been fully loaded. However, when I attempt this on form load the image doesn't show up? I also can't perform simpler things such as changing the row background color on form load. Should I be performing this logic in a different event after form load?

Using VB/VS 2010 and am trying to provide the user with a way to change the color of the control buttons on my main windows form. I'm starting with the button click event that then calls another sub-form (code shown respectively below).
I was testing with DirectCast as I need to deal with a multitude of button controls (i.e., will have more than the two shown below).
I would like to know how to deal with the following:
1. How do I save the BackColor so when the user opens the form for the first time (or any other time thereafter) the color set earlier appears (the default via properties is green).
2. When I click on the button for the first time and change the color it doesn't change until I click the button again.

Using Visual Basic,change the backcolor of the upper left header cell (.rows(-1).columns(-1)) of a DataGridView? I would like to use a different color to indicate to the user that he/she can right click a row or column header to access the Context Menu Strip. Not all of my DGVs use a CMS, so I would like to highlight its availability for the specific DGV.

I want to change the orientation of rows and headers in a datagridview using a deserialised class as a dataset so that rows are displayed as columns and columns as rows. How do I do this?
View 9 RepliesI'm looking for a way to change the font colour on alternate rows within a datagrid. e.g. normal row would be green and the alternate row would be blue. I can change either by using
me.datagrid.Styles.Row.Forcolour
me.datagrid.Styles.AlternatingRow.Forcolour
The problem is that I am having trouble using both of them together as I need to manipulate both colours. I have created a HtmlRowPrepared event and have been setting them there, however, If I set the Row.Forcolour first, it will over ride the AlternatingRow.Forcolour and vice versa. This needs to be done via SEVER SIDE code only as the colour choices are held in the database.

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
I have a table of 51 data points all numbers between 0 and 8000, i have stored the data in an array of ushors's, and on my form i have 10 numerical text boxes, So that the user can change the values in the table every 5th value. Using the value changed event the program then re-calculates the values in-between.
What i would like to do is show the table in a data gridview and allow the user to change the values in the array using the datagrid view, i know how to create a table but not how to link the table, so that it can change the values contained in the array.
Below is the code i am using to create the table:-

View 1 RepliesOur site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

I've been trying to get a loop through a row in just one column in VB.NET for a while now, and i've done my homework on it too. When i use that code above I get:
Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.
I saw another guide which told me to do:
For Each row As DataGridView In dgrFarms.Rows
sendtroopid = row("idColumn")
'Do Something

But that gives me the error:
Overload resolution failed because no accessible 'Item' accepts this number of arguments.

numbering rows in datagrid. I have a column that should number 1,2,3 so on when adding a new row. When I delete a row, those numbers should re-number still to 1,2,3. So when I delete row 2, the row that's been added as 3 should now number to 2. Then when I add new rows, these should re-number again, and so on..
My code:
