I am having a loading problem, the problem is my formating code takes way to long to load.
What I have is a datagridview that is loaded by one table and I want to format the cells based on data from another table, the following code works, but it gets slower and slower as I add more records to the data.[code]...
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 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)

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.
View 1 Repliesim 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 can change the color of the return value based on conditional statements but cannot figure out the correct syntax to change the table cell back ground. My attempt is commented out.
How do I correctly declare the table cell? Findcontrol must not be the correct way.
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.
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
Here is what I need to do: I need to be able to go through the cells in my first column and find any that have four digits (and only four digits). When a cell is found with a four digit number I need to be able to bold that entire row. How can I do this?
I'm in VS2007. This is a datagridview program. Data populates the tables from a database. The cells in the first column that contain the data can contain between four and 8 numeric digits. I only want to bold the rows that have cells in the first column that have four digits.
My datagridview consists of Three columns.
1st column is Datagridviewcolumn
2nd column is datagridviewcheckboxcolumn
3st column is Datagridviewcolumn
so 3rd column i made as readonly.so i need to enable the 3rd column cell based on the checkbox check properry
so i am generating datagridview column dynamically and populating values in the datagridview dynamically.so my need is after populating the value if i check the check box the current row of the 3rd column cell has to be enabled. so how to do this. please show me some sample code if there any. please
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

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 want to make a certain column of my datagridview red based on values from 2 other columns. I have a "HI" column, a "LOW" column and a "Result" Column which are all strings. Now I want to make the result column red if it's values is less than the "LOW" columns value or if it's value is greater than the "HI" columns value. I tried the following code but something is wrong because cells that shouldn't be red are red:
Private Sub dgvTests_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgvTests.CellFormatting
If dgvTests.Columns(e.ColumnIndex).Name.Equals("Result") Then
Dim RowValue As DataRow = TestTable.Rows(dgvTests.CurrentRow.Index)

I'm working with a DataGridView that I want to format based on the condition of whether or not a date has passed.

I have a DGV where I'm setting the backcolor of certain cells to light gray. But I need to be able to restore the backcolor to what it was before I changed it to gray. I could just set it to transparent, but the problem with that is that I use an alternating row color of alice blue for the DGV & setting a cell in a blue row to transparent makes it white. So, in summary, I need to be able to restore white rows to white & blue rows to blue. Any ideas? I thought about checking the backcolor of another column in the row & then using that to reset the cell, but that seems kind of a hack.
View 1 RepliesI've been trying to customise a datagridview but no luck so far, thing is, i want some of the cells to not have the same grid colour and width as all the rest of the grid. Do you guys know how can this be done? I know it is possible cause i've seen it before but i have no clue how to accomplish that.
View 4 RepliesI have a SQL database, with some "status" strings. For every status I need to display a .bmp image .
I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:
Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)
I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.
I edited the DGV, and add a new image column.
I created a directory in my solution called "references" where I put all the .bmp files
I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.
LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?
Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.
How to change vb .net datagridview row color based on grid checkbox value. Having bound DataGridView. BindingSource as data source. called DGV. I m using this code under cell_formatting event
[Code]...
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 would like to be able to show the defaultstyle of the cell in the form load

I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.
How I can change the back color of a single cell of a datagridview in runtime?
View 1 RepliesHow to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.
I am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4. The catch is I don't want it to update every time the sheet is recalculated due to updating links in other cells on the sheet. ONLY when Cell A4 Changes. What do I do?
