Unable To Get DataGridView Row Color?
Feb 23, 2012
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.

In VB6, there was an issue of not being able to color just the tabs of the tab control. It appears this is still the case in .net, yes? Does anyone have a way to paint the tabs of the tab control

I'm unable to get the color to display in the colorLabel. I think the problem is in my selector expression. I tried "B", "##[B]##", "##B##"
Option Explicit On
Option Strict On
Option Infer Off

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'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())
End Sub

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.

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'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?

When I modify and delete data in a DataGridView, I get the error:
The record cannot be deleted or changed because table 'Table Name' includes related records.
but I can add new data, only cannot modify and delete data.

I am displaying a Master-Detail tables in a DataGridView. The Master has only one table and the Detail also has only table. Both tables have primary keys. I would like to give the user the capability to delete one or more rows from the Master or Detail when they click on 'Delete' buttons. I am using VB.Net 2010, MS Framework 4.0 and Win 7. The database is Oracle 10g. I have written the following code but it doesn't seem to work. I keep getting 'Number of records updated: 0'.
Here is the code to delete from Job table (Master) when the user clicks on btnDelJob:
Private Sub btnDelJob_Click(sender As Object, e As System.EventArgs) Handles btnDelJob.Click
Dim i As Integer
Try
Dim response As DialogResult = MessageBox.Show("Are you sure you want to delete these rows?", "Delete row?", MessageBoxButtons.YesNo, _

First of all I am using vb.net(2008) and i have an application which connects to a database and is able to modify it.
My problem is that when I modify a row and try save, It doesnt save to the database although when I add a new record it does save.
Code I use to Save
Me.Validate()
Me.MessagesBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.ServerDataSet)
[Code].....
PS: When I Delete the row it works but when I try updating the database by saving it it doesnt work. Is the Database row event handler able to help my case?
I posted this in the database development section but i didn't get a reply after a day or so

i have a datagridview which has a datasource of a SQL database. In this database i have a column which has a boolean value, and in my form, it is used to specify whether a checkbox is ticked or not. What i need my program to do is color the cells of the datagridview based on if the checkbox is ticked or not for the particular rows which have it ticked in the database. Here is what i have, but it doesnt work:
Code:
Dim count As Integer = 0
While DataGridView1.CurrentCell.RowIndex <= DataGridView1.RowCount
If CellIDCheckBox1.Checked Then
[code]....
what im trying to do here is loop through the datagridview and see if the checkbox is ticked or not and coloring it based on that.i have also been messing around with some LINQ code, but that doesnt seem to work either..

I have a bunch of columns in a datagrid view (date, transaction type, amount).If the amount in a row is '150.00', I want to make that cell red.I made a Private Sub and run this after the datagridview is filled.
Private Sub ColorCells()
Dim ColumnCount As Integer
ColumnCount = dgvLedger.ColumnCount - 1[code].....
However it seems to have two bugs. When it is first run the first time when the form is loaded, it doesn't put the rows with 150.00 in it in red.If I have a button on the form and set it to run this Private Sub, then it runs through it again and will color the ones in 150 as red.If I resort the datagridview by clicking on a column, they all return to green again, and it looses the formatting.

I'm filling a DtatagridView as usual, using a datatable as datasource and I have the SelectionMode = FullRowSelect, but since I need to color each row according to its result, I have set the property DefaultCellStyle - SelectionBackColor = Transparent, well, I'm not going to complaint about the font looks a little bit distorted, but about the selectedrow does not render correctly, If I minimize the program and then maximize it, the selectedrow appears with the image of the desktop's background.

I have a datagridview with the rows color coded for specific values...To make it easy on the user, i want to do what I did in vb6, something like
MSHFlexGrid1.BackColorSel = MSHFlexGrid1.CellForeColor
MSHFlexGrid1.ForeColorSel = MSHFlexGrid1.CellBackColor
basically, when a user selects a row... the colors should inverse. for instance, if the background color is red and the foregrould is black when the user selects the row, the foreground becomes red and the background black... and then goes back to its orginal color when the user leaves the row.

How would I sort or filter the datagridview so that only cells that are color.red are viewable? What I have now shows all of the red and not red cells with the values <=0 else color.black. But if I were to put this on a button I would want only to see the color.red cells on the gridview.
Try
'##############################
For Each dgr As DataGridViewRow In dgProducts.Rows
'##############################
If CInt(dgr.Cells(4).Value) <= 0 Then
dgr.DefaultCellStyle.ForeColor = Color.Red
Else
dgr.DefaultCellStyle.ForeColor = Color.Black
End If
Next

I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.
