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 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 am writing some data from database to the excel via visual basic.net.I need to change background of some cells and also need to make text bold. I need something like that :
xlWorkSheet.Cells(rownumber, 1).BackgroundColor = Color.Yellow
xlWorkSheet.Cells(rownumber, 1).Font.isBold = True
Of course none of above is works.How can I achieve this?
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.
View 7 RepliesI am working on a vb6 to vb.net migration project using vs 3.5. I have a datagridview.in a particular cell of this grid, user has to enter only numeric data. but after user enter data, itshould become concainated with a $ symbol (eg: if user enter 34, the cell value should become $34). And if he/she presses the hyphen ("-") in the key board, the data (ie. $34) should become -$34 and if again presses the hyphen button in key board, the data should become $34.
View 3 RepliesI 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

I have a datagrid view with 8 columns. How do I change the background color for any cell in columns 2-5 where the value equals the value in column 8. For instance:

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.

View 6 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 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
View 6 RepliesI am filling a DataGridView from a table in SQL Server 2008. There is one column that is a string which contains either "YES" or "NO".When I run and display the DataGridView it displays perfectly. For the User's benefiy, if the field contains "NO" I want to put some emphasis on it by changing the fore color and back coler of the entire row. In the DGV the index for field is (4).I tried this code which threw an error on the word "value" inthe block that fills the DGV.
IF DGV,Columns(4),Value="NO"....

View 10 RepliesI 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 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.
