Color Datagridview Based On Database?
May 15, 2009
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'm working with a DataGridView that I want to format based on the condition of whether or not a date has passed. For example: If the date in a cell is past the current date, that cell and its row are formatted with the forecolor red. My current code is below, and while it doesn't present me with any errors, it just plain doesn't do anything.
Private Sub dataGridView1_CellFormatting(ByVal sender As Object, ByVal e As DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
If Me.DataGridView1.Columns(e.ColumnIndex).Name = "Due Date" Then

I have a DataGridView that has been dragged over from the DataSource Tab. All works good.I need to have the background color of some of the cells changed based on other columns in that same row. Such as, have the background color of a cell Red if the Status column (not shown) relates to 90 days overdue. The next row may be different.

I am populating a datagridview not with a datatable but with a list of instances of a class I created. The data for the instances is read from a database.
Looks like this:
Public Function GetSecurities() As System.Collections.Generic.List(Of Security)
Dim com As New SqlCommand
Dim rdr As SqlDataReader

I have a datagrid that will get built at runtime. So i don't now how many columns I may have.I know I can do a column count, and get a list of the names. So don't think that will be a problem.What I'm trying to do is change only the CELL color, not the row, or the column, based on the value of the cell.Below is something I started with, but it clearly doesn't work.
' For Each row As DataGridViewRow In Me.QDGV.Rows
' ' Get the READY value from each row as we loop
' strExt = CStr(row.Cells.Item(4).Value)

My gridview does not use controls, because it is populated using expressions
<asp:TemplateField HeaderText="As Of Sales">
<ItemTemplate>
<%#Getsales(Decimal.Parse(Eval("asofsales").ToString())).ToString("C0")%>

In an application for a Storage company, I have a form with 107 buttons in five Group Boxes. Each Group Box represents a Building and each Button represents a Storage Unit. They are layered in Table Layout Panels, bottom TLP has 5 columns, one for each Group Box, each Group Box has a TLP with 2 columns and 10 rows, where each button is located. What I would like to do is change the color of any button based on the results of a query.
Buttons are called btn1, btn2, btn3..... Text on the buttons is 1, 2, 3, 4,.... I have a table for the buildings and one of the properties is "Available" set as an intger and is either 0(No) or 1(Yes). I have a query that I run on form load that returns the correct results, to test I put a DGV on a form and set the DataSource to the DataSet returned. Returned is the "Available" Buldings Number(1-107)[code]...

I've created a program that requires students to answer addition questions.I have the code so that it calculates if the answer is correct, along with outputing the correct answer into a textbox.If the answer is correct the textbox background colour changes to green.If the answer is inocrrect the textbox background colour changes to red.I've done this using an array, and I want to use this array to calculate how many questions the students have answered correctly, and output them onto another page.I'm not sure is something like this would work:I was thinking about giving the textbox that outputs the grade score a value of 10. For every red box that is highlighted, 1 is taken away from the texbox value, outputting the amount of questions the user has answered correctly.Here is my array so far, not including the ability to output how many answers the student has answered correctly.
Public Num1(10), Num2(10) As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

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 developed some software(vb.net) that records fees paid by the students. The purpose is that the database should be stored in a server, which can be accessed from any stations linked with it.This is working fine with a network of 10 computers. I need to publish it over the net so people could do this job logging in over internet. Database (access database) should be stored on a web based server.

Recently working in vb 2010 express. I'm using service-based database which is based on SQL Server. This database will be deployed at the server. Is it possible that multiple vb.net programs, which are installed in remote computers or client computers in the same network, connect to this database simultaneously? Does the service-based database support multiple connections?

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!
