I need to be able to double-click a row or column in a row to use a field (in this case the Student ID field, the 4th column if counting form 0) to get that row from a database onto a separate form and be able to edit and save it. I have no idea how to make this happen since it is not covered in the class beyond basically displaying database data in DataGridView, I chose to use this functionality in my final project (to be fancy I guess) with the thought that it will be easy to accomplish but am finding it is not quite as easy as I thought. My current code is below;

I am currently trying to develop a program where you click on a datagridview row and then at the bottom of the window there is a button called "Modify."Once you hit this button, another window will pop open to where the user can modify the information on that specific datagridview object.I want the program to fill in what has already been entered so the user can go back and make changes if need be.I understand that datagridview has it's own update commands, but when I created by table adapters and everything, it did not create them.I am not sure if there is a way to create the update command manually, but this is the best way to explain it.
View 2 RepliesI have a DataGridView with SelectionMode = "CellSelect". I do this because I want the user to be able to click the Column Header and drag the column to a different DisplayIndex. They move the column by clicking and holding down the left mouse button, then moving the column. I also want the user to be able to click the column header and all the cells in the column would be selected. But if I change the SelectionMode property to "FullColumnSelect" or "ColumnHeaderSelect" the user can no longer move the column.In the code below, I can select all the cells in the DataGridView just fine, but I can't select all cells in a particular Column or Row.

I am relatively new to VB but have written a few VBA applications.I want to write a context menu item for Firefox that allows the user to right mouse on a field that is being displayed and take some action.Is it possible to identify the field the cursor is on and pass the entire value to the vb program? If so which namespace should I be searching for methods? Can this be done without selecting the field's contents or does the user have to select the field?

Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!
The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!
In the datagridview control in vb.net you have certain mouse click positions where a certain mouse click event is "recorded" like seen below:
Dim hit As DataGridView.HitTestInfo = DataGridView1.HitTest(e.X, e.Y)
Select Case hit.Type

PS: I have modded a little bit this datagridview so it looks like a gantt chart with collapsible rows, and variable & multiple timelines at the same time, so the bars might go a long way to the right of the screen, that the main reason for the save to bitmap.
