Masters of the visual basic arts, I, a lowly noob, would just like to ask for your wisdom (and mercy). For my program needs to determine if the data grid view has any content because if that certain datagridview doesn't contain anything, then I would disable a couple of functions for the program.

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

View 2 Repliesi have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.
View 1 RepliesI have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

View 3 RepliesI need to display (read-only, I don't want the user to be able to modify the data) a set number of log entries. I figured using the data grid view would be the best solution. Basically the data is an error log that contains 3 fields (columns)
ID (a number from 1-20), Flag (number from 0-255), and a Description (string). I don't want the data linked to any database or anything.
These events occur asynchronously so I need to be able to add events (rows) to the data grid as they occur.
I also need the ability to clear all events (rows).
I guess the first question is if the data grid view is the best control in VB to use.
Is there a good example on using the data grid on how to add data to the data grid view one row at a time?
I need to restrict the user to enter only integer value in a particular columns in a Data Grid View. How to do this?I tried with "KeyPress", "KeyDown" & "KeyUp" events. But not succeeded.

I have to turn this program in TOMORROW! I can't seem to figure out how to do this section. If someone I can do the second part.I have two text files, one is a single dimensional array, and one is a two dimensional array. One titled "Months.txt" and the other "Rain.txt".The problem is I have to read those into an array, and then after that, use a query to pull the information and display it into a data grid view style box.The problem I'm facing is when I pull the "Months.txt" text file, which has the months in order from January....December, and try to display it in the data grid it puts the length of the names of the months, not the actual months. me on this matter? I've tried to no avail. Also, how would you add all of the numbers in a single row of a two-dimensional array to give a total to display in the data grid? Also, the column?
