I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.

Private Sub HistoryTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HistoryTextBox.TextChanged
If ugHistoryButton.ActiveRow.Cells("Dog").Selected = True Then

It just doesn't seem to want to transfer over when I select the cell in the 'Dog' column.
using code, how can i goto to cell which row = 3 and column is 4?
View 7 RepliesI would like to update an Excel cell using the cell name, such as "A1", instead of using the row and column, such as (3,2). I haven't been able to do it. Here is the code I used to update the cell by row and column. How would this code be updated so that it updates the cell by cell name instead?

I'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?
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.
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 have a loop that will determine if a certain value is within the specification limits that I assign. The problem is, when the loop starts, I get the following exception:system.InvalidOperationException was unhandled Message=Cell provided already belongs to a grid. This operation is not valid.
I'm not sure exactly why I am getting this exception...OF COURSE the cell is already part of a grid! I just want to color it! Anyway, here is the code I am using:
Private Sub ColorAllCells()
For row As Integer = 0 to dgvCurSetLanes.Rows.Count - 1

The exception occurs as soon as I call ColorAllCells
I am using vb.net and I have an asp.net application where I use ExcelPackage. I wanted to know how to set the background color of a particular cell or a row of cells.

I have a datagridview which I would like to change the the color of the text in a cell if the number is negative in the Total column. This is what I have so far.

Dim Total As String = TTLGrid.Rows(x).Cells(4).FormattedValue

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

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.

' For Each row As DataGridViewRow In Me.QDGV.Rows

' strExt = CStr(row.Cells.Item(4).Value)

How would I find the weekends and change the cell color to a different color then just regular week days?
Is there a way to locate a cell by back color? I have a datagrid, that will populate names, on some of the cells. Some of the cells will be empty.
I have it so if there is a name in the cell, the background color will change to blue. I also can look for a specific value, and locate the value that way, and then change the color the cell or whatever.
The problem is that I have 4 different status for a cell with the same name. So for example, "Joe" name will show up in the grid. That cell background will turn blue.
The next status is "Check-In". So I can return the value "Joe" from my database with a store procedure, and look for that value of "Joe" again, and change the color to red to show he is checked in. The other 2 status I have is In Session, Session over. The problem is what if there is more than 1 "Joe"?
I think the best way is using the datagrids CellPaintings. But I can't find any other value beside a value to locate a cell on that procedure. So I thought if there is a way I can find a cell by the e.value = "Joe" and cell.backcolor = color.blue, than I can avoid having problems with multiples names.
I would be open to any other ideas, or a better way of doing this. Oh, is there a way to use tags for a cell value? I thought that might be a way was well.

completely understand what it does, when the cell value is changed the color of the cell changes according to the value selected.
Now, how would i change this code so that it works when the form loads? so cells show the color when the form loads. red for unpaid and green for paid.
I am having a loading problem, the problem is my formating code takes way to long to load.
