I have a BackGroundWorker that produces a DataTable which is then bound to a DataGridView.
I want to have selected rows of the DGV colored based on the value of a column within the DataGrid (1 if coloured)
How can I set the row color while populating the datatable? Or do I have to set the color on the DataGridView after binding it to the datagrid?
I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
Is it possible to store color values in a data table? Such that when these values are loaded into a datagrid, the datagrid will display the color.
View 2 RepliesAt the moment I have a DataGridView (bindet to a DataTable) and some labels. If DataGridView's event SelectionChanged occurs,the labels should be filled with the information of the selected row -> No problems.But if I sort the DataGridView and click on a row, the informations in the labels are wrong.
Event:
Private Sub DGVMain_SelectionChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DGVMain.SelectionChanged
If DGVMain.SelectedRows.Count > 0 AndAlso Not Me.DGVMain Is Nothing Then[code].....
My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"
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 to do a system that will trigger an alert. i need to change the color of the box in datagrid view to certain color, according to it's condition.
as example, the first alert will be trigger if there is any values that are below 5. so all box in the datagridview that contains value less than 5 will change to red color.
When I bind the data to Gridview after that i want change the Datagridview content color

I'm working on a program that does a bit of color-coding in a datagridview. My problem is that when a row is selected, the color-coding goes away since the normal behavior for the datagridview is to change the back-color to blue and fore-color to white. What I want it to do though is keep the fore-color that is being set through my code. I guess what I'm trying to find out is if there is an event that happens when a row is selected that I can modify to run my own color-coding. I posted a link below to an image of my program that what I'm talking about. My color-coding code is below that (if anyone would want to know what that looks like). gets solved I'll be sure to post the code solution!

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..
Code:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
GeneratePODetailsView(GenerateDataSource())

im working in visual basic .net,i have a datagridview like this:[URL]...I want that when the user selects a whole row, only the values of the cells that have colors will be saved to textboxes, something like Textbox1.Text = cellwithcolor1, and so on with other cells that have color. Like, if we see the image, in row 3, 'AS' will be saved in textbox1, and 'CR' in textbox2.

My application uses 3 DataGridViews in asingle Windows form. The 3 are never visible at the same time, and I have a sityation that I cannot figure out. The first examole below works perfectly:
For Each row As DataGridViewRow In dgvBooks.Rows
If row.Cells(4).Value.ToString = "YES" Then
row.DefaultCellStyle.ForeColor = Color.Red
[code]....
The only difference in the 2 blocks of code is the name of the DataGridView. I'm at a complete loss to figure out why one works completely and the other only partially. I have checked the execution, one step at a time and everthing happened at the right time and accurately, The upper case string is correct as is rhe index designation of the field, and I'm lost for a reason.
I'm filling up a datagridview from a datatable which is populated by sql queries.
So the idea is to display all the items in an order.
Now as we scan each item, i want to change the textcolor/backcolor of the row that lists the item scanned.
any inputs on how this can be done?
I just want to know on how will I add a Checkbox in each row of my datagridview. First I used a datatable to get all the values from my database and then pass it all to the datagridview. What I want to happen is at the first column of my datagridview there is the checkbox.[code]

I have a datatable dimensioned as new.I add the columns that I need (during the form's load) I have a datagridview as on object on my form and set the datatable as its source.The table is loaded with values and they display properly.The User closes the form and returns to the 'Main' form. At this point no problems, everything is working great. NOW...The user re-opens the form containing the datagridview It has the values from the previous time it was open, plus the new values ! I have tried several things so when the user goes back into the form it only has the new values, but it always keeps the previous values and appends the new values to it. I have attempted to clear it by adding a line: datatable.rows.clear(); I have activily gone through the datagridview one row at a time and use a statement to clear the cells;
For Each DGVRow As DataGridViewRow In Me.DataGridViewErrorList.Rows
DGVRow.Cells.Clear()
Next
so far no luck.
I'm selecting value from my database, passing it to datatable then giving DataGridView.DataSource value of datatable.The thing is that in those rows i'm also selecting some dates and problem is that my default date in database is '1900-01-01 00:00:00' because i use "smalldatetime". And what i want is this...when I find default value in database i want to show it like an empty string, like i said...because date is in smalldatetime format i can't do this in SQL query so i wonder how can I change this in DataTable or even better in DataGridView...of course, in code?

I developed a windows forms app, using VisualBasic in VS 2010. In my form, first I declared a variable as DataTable (Dim VarTable as New DataTable).
Second, changed the DataSource property of my DataGridView (DataGridView1.Datasource=VarTable)
Third, I filled the VarTable in this way: using a resulset from SqlDataReader, i added row by row.
Dim Result As SqlDataReader=CommandSQL.ExecuteReader
Do While Result.Read()
Dim RowToAdd As DataRow
RowToAdd=VarTable.NewRow()
RowToAdd("Code")=Result("Code")
RowToAdd("Name")=Result("Name")
VarTable.Rows.Add(RowToAdd)
Loop
Fourth, after the user changed data in datagridview, I saved the data back to SQL, cleared VarTable (VarTable.Rows.Clear()), and back to top of form to accept a new code. But here, problems begin. When I execute again the whole code described, the datagridview dont show the entire rows, and sometimes crashed with different errors. Solution? Dont fill VarTable row by row. Use VarTable.Load(Result) to populate the VarTable. I don't know why now works, But just I wanted to share this information.

View 5 RepliesIf I have a datagridview's datasource set as some datatable, is there a quick and easy way to reflect the changes in the datatable that have been made in the datagridview?
When I sort my datagridview, the rows in the datagridview and the datatable no longer match up.I know I can catch when the dgv is sorted and for-loop through the dgv and send it to the datatable, but I was hoping there was a save/update method or some such thing.
I am using the DataGridView for editing data, but when I go to access the DataTable bindings there are no data. I used to bind the following

dgDettagli.AutoGenerateColumns = False
