ToolTips For Individual Cells In DataGridView?
Jun 15, 2011
I am developing an application in vb.net 2008 express edition that displays utility meter information. In one column of datagridview it shows the meter type in numeric code. When the user hovers over the the individual cells in meter type column i want to be able to show more descriptive info on what that numeric code actually means.
As an example the cell in datagridview will show 1254 the actual description for this numeric code is "Landis Gyr Focus AX SD 2S 7.2Kh"
Below is my code so far, every other aspect of application is working except for above.
Public Class Form3
Private Sub dgv1_CellMouseEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgv1.CellMouseEnter
[Code]....

Is it possible to give individual cells in a data grid view row different styles such as backcolor, fontcolor etc?
I do not mean giving the whole row a new style, only a specific cell.

I want the user only to be able to select rows and not individual cells in a VB.NET DataGridView. Is there a way to make this happen? I don't see an option for the DataGridView object to control this via properties.

I have a mature VB6 program that depends heavily on flexgrids for the display.It appears that DataGrids are somewhat of a replacement for flexgrid?I need to update individual cells over and over and I don't see how to address a single cell. Appears to me that most samples are tied to a database which I don't have.If I set up a datagrid that is say 3x3, how do I read and write from and to say the center cell?

I am having trouble with automatically filling a table in word from a asp.net app - i use bookmarks in the next top row to determine what data should be inserted into the columns of my tables. However, i am having trouble in getting the individual cells bookmarks and get all the bookmarks from the row instead. This is fine if i have one bookmark in each column as i can use the 3rd bookark and assume that is from the 3rd column, but if i were to have 2 bookmarks in one column, how would i know which column it was that contained the 2 bookmarks?Here is my code that returns all bookmarks for the row even though i am selecting a single cell; and therefore using bookmarks(1) - always the same bookmark(the one in the leftmost

I have a DataGridView (not data bound, not editable) that displays a bunch of data. I want to draw rectangles around some of the blocks of cells to set them apart visually. For example, I want to draw a red border around the block of cells from row 3 colum 2 to row 6 column 3 so that there is a red rectangle around the 8 cells.I've found how to paint rectangles around individual cells or rows, but I can't work out how to do it for a block of cells.

I'm wanting to display tooltips on cells on a DataGridView.This works normally but in this case I have the DataGridView with enabled = false as I don't want the user to edit it but I do want the tooltips to be shown. If I set enabled = true then it's OK.

I need a few columns in my datagridview to have the font be aligned to the right, but no matter what code I use it doesnt work.
I would also like my columns with numbers to always have 2 decimals.
And lastly I would like the right side of the column header to be blank and not movable. I can do this by adding another column to my table with a blank name and then set the width to fill, but the problem is I can just move this around, which is not good, I want to freeze it so it looks good. I do want to be able to move around on the other columns, just not this one. Unless there is another way to do that?

i wanna compare my cells in datagridview. I have a datagridview with n columns and n rows. I have my datagridview row value as Time . I need to compare all the row cell values with one particular time.
Here you go with an example.
if my dgv is filled with time values such as 3:42:10 AM 4:43:17 PM etc..I need to compare all the cell values to 5:00:00 PM. greater than condition. I need to highlight only the values which are greater than 5:00:00 PM but less than 3:30:00 AM.

I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.
