View 2 Repliesi 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.

I have a Windows Form VS2010 .NET 4 project with a standard DataGridView bound to a datasource on a form.
The grid has a text column that I want to be a point and edit at the character clicked to. Like normal textbox/editors when you click on the character you want to adjust. If possible I would also like to use the UP/DOWN keys to move between rows but would like the cursor to move to the same character position obviously in the same column without selecting the entire text.
I have tried a few things:
DataGridView1.ClearSelection()
DataGridView1.BeginEdit(False)
The BeginEdit just puts the cursor at the end of the text, which means another click to point to the character position for editing.
I know a Commercial grid like DevExpress defaults to editing in which you can click to the correct character position with one click but obviously costs money.
I have tried in the DataGridView1_EditingControlShowing event
If TypeOf e.Control Is System.Windows.Forms.DataGridViewTextBoxEditingControl Then
Dim tb As TextBox = e.Control
tb.SelectionStart = 5
[Code]....
I am just trying to remove the two or three clicks to get to the character position that needs adjustment.

View 12 RepliesI have a DataGridView that is showing some weird numerical data. For example, my under lying datatable of the datagridview has 4.69, but the datagridview shows 4.6899999999999999995. What is weird is it doesn't do it for every cell in the column. For example, my underlying datatable has 2.66 and the datagridview cell shows 2.66, which is correct. I should note that the underlying datatable column that contains the numbers is of floating point data type which comes from the database column and the datagridview column is TextBox. Here is what the values look like in the database, underlying datatable and datagridview.
