Datagridview Rows Alternate Color?
May 6, 2009
Basically,I would like to bind the data into datagridview which called PODetailsGrid during page_load. After the data had been bind into the gridview,I would like to make alternate color in each row. For example, the font color for row1 is Black,then second row should be Red,then third row will be Black again and so on..
Code: Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
GeneratePODetailsView(GenerateDataSource())
End Sub

I was looking for some code that would change the colors of some rows in my datagridview but I could not get that to work. I have this code which should work but it doesn't, I could not find any replacements. I need to change the color of some rows.
Do While cnt > -1 If datagridorder.Rows(cnt).Cells.Item("DataGridViewTextBoxColumn16").Value.ToString.Substring(datagridorder.Rows(cnt).Cells.Item("DataGridViewTextBoxColumn16").Value.ToString.Length - 5, 5) = "Cease" Then
datagridorder.Rows(cnt).DefaultCellStyle.BackColor = Color.Red
End If
cnt -= 1
Loop

I'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.

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.

I'm faced with another issue I would like to have resolved. I have filled my dataset with records from a table and successfully displayed it in a DataGrid. Next i would like to change the background color of certain rows or records in the datagrid using values from a column. E.g assuming my first column stores numeric values, I would like to have records where value in column greater than 6 have it background changed to a different color.

I am developing an ASPX file to return all records from a SQL table. I can successfully get all of the numbers to show, but now I want certain rows to have their background colors changed if they meet certain criteria. So I want to compare 2 of my columns to some value, and if it exceeds this value then it should change color of that row. How can I fix below code? Main problem is I don't know how to specify a column of data to compare. No errors on this, but none of my rows have color changes either.[code]...

I know that this has been asked alot on the internet and i've searched for it, but can't find any good thread/page about it.What i wanna do is:I have a listview where the user can add items to. But i want the user to able to choose backgroundcolor.The only option i can find is ForeColor, and it does nearly what i want, it colors all text on the row the user add. But as I said I want it to color the background of the row, not the text.

I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:
[code]...
There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".

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?

I have populated a ListView with currently running processes and with the help of JMC, been able to highlight specific rows based on memory consumption. However, I've decided to change it up a little bit and change the color of rows based on whether the process is owned by the User, if it's a System process, or if is a Service. I've already been able to determine if the process is a User process by utilizing the OpenProcessToken.

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

I have a datagridview that has two columns with combobox's in them.
On a previous windows form a number is entered and passed to the function which populates the datagridview.
How do I add rows based on that number? So if 2 is entered two rows are added.
In the combobox's players name are added from a textfile.

My datagridview is bound to a data table. I want to filter the datagridview without affecting data table. I know one way is to use bindingsource, but binding source will use column names in its filter. But I want to enable users to enter any string in a textbox to filter. So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview. But the problem is that when datagridview is shown on the form, it is unchanged, the same as the data table. I do not understand why rows are not removed on datagridview The code is as follows:
