I want to Highlighting a Datagrid Row based on a column value.I've refreshed my DataGrid and now I want to go to the row that contains a specific value.ie, 2 Columns NAME, ID 1000 rows.I want to highlight the Row with ID = 700.[code]
View 6 RepliesI 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)

How to highlight the row once the value of the cell is change
View 7 RepliesThe problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

I want to do so in datagridview with a currentcell.
I am working on a page where I need to highlight different events in a day with different colors in a ASP.NET Calendar Cell. The events are store in a database with a start date column.
For example, if we have two different events for today, the cell should display half green and half red color. If there are three events for today, it would 1/3 green, 1/3 red, 1/3 blue in the cell for today.
In addition, currently I use tooltip in jquery to hover a cell, it would display a tooltip above the cell. How to handle this when we have different events in one cell?
Does anyone know how to highlight or change the color of text inside a datagridview cell? Not change the back or fore colors of the whole cell, but only for a particular word inside the cell. This is to make the search results more visible to the user.I tried doing it in the Cell_Formatting event of the datagridview but I'm only seeing options to change values of the entire cell (e.CellStyle). If there was only a way to select text inside the cell and set the selected text's properties. Or if I could use some formatting tags around the text.
View 14 RepliesI want to change the row color of every row in my DataGridView where a particular column value = "RBF3". I am currently using the DataBindingComplete event which seems to work fine, but it fires every time I change a cells value. I'd like for this bit of code to only fire when the datagridview is first displayed, sorted, or filtered. Is this possible?

I have searched alot but can only find info on moving entire rows bound between 2 datagrids, but noting on moving single cells. I have some code below that works ok from DGV to textboxes but not from DGV1 to DGV2.

Form3.DataGridView1.Item(1, i).Value = DataGridView1.Item(0, i).Value

I have a datagridview and in the _CellValidating event I am checking a cell to make sure it is filled in. If it is not, I want to stop editing, display a msgbox, and highlight the particular cell. Here is my code :
If e.ColumnIndex = 2 Then
If e.FormattedValue = "" Then
If Me.dgvFish.IsCurrentCellDirty Then
MsgBox("Sample Number is a required field.")

For some reason, I can't get the cell's backcolor to be filled in.
i need bit of support in my vb coding. i've publish data onto a datagrid(in vb express 2010). i just want to highlight entire row once the search data is found(in lime color) and color should be remain in that particular row when searching next records. so that user would easily know which records are searched and which are not by looking @ the color.
View 2 RepliesI have a ListView that I populate with running processes and would like to highlight specific rows based on the amount of memory consumption. After I add the processes to the list and and call the WorkingSet64 property of the process, I tried this:
vb.net For Each lvi In ListViewProcess.Items If proc.WorkingSet64 >= 2000 Then lvi.BackColor = Color.Yellow End If Next
Processes is the variable I used to grab the collection of processes. proc is defined as a variable and then used to loop through the processes.
lvi is of course the ListViewItems in the ListView.So, by the code I have above, I loop through the ListViewItems, and if any of the processes are above or equal to 2000, then I set the background color to Yellow.
However, it sets every line to yellow, and I can't seem to figure out to set only those processes that have a WorkingSet64 above 2000.
Would I need to loop through the processes and then set the background color of the ListViewItem based on that? That kind of makes sense to me, but if I do that, I'm not sure how to set it just for those processes. Maybe by setting a separate variable?
I wanted to identify the conflicted schedule of each of the section. If there's conflict then the two or more subjects that are conflict will be colored to make then noticeable. They are in datagridview. I don't know what's wrong but there are some that although they are conflict they are not highlighted. Here's my code:
For item As Integer = 0 To DataGridClass.RowCount - 1
For item2 As Integer = 0 To DataGridClass.RowCount - 1
If DataGridClass.Rows(item).Cells(ClassID).Value <> DataGridClass.Rows(item2).Cells(ClassID).Value And

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.
write a macro that removes the letters "TBD" from any cell it is in in a range of cells (J5:PJ421)n a different worksheet. This is probably very simple, but I am new to VBA and can't figure it out.
