How do I trigger a sub after the user hits the Return key within a cell in a specific column in a DataGridView. I know its columnIndex 1 that I care about. I want the sub to fire when the user is editing (i.e. DataGridView1.CurrentCell.IsInEditMode = True).

I have a program that gets some information from the user and updates the database.I also have two DataGridView, OpenOrders and ItemsInOrder When the user click on a cell in the OpenOrders a CellChange event is triggered and it updates the ItemsInOrder grid view. Now after I update the quantity of a product i want to cause that CellChange event to trigger again in order to refresh the ItemsInOrder grid view.
View 7 RepliesHave this code so that when a checkbox in a column of my datagridview is checked, then the corresponding cell in column 2 (of the same row the check box is in) will turn blue with font color white.

I'd also like to add a line so that as well as the cell going blue, the bottom border of the cell disappears, so cellborderstyle = none.
I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

View 5 RepliesI have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode)
PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then
Deletecustomer(n)
End If
I'm not sure how I can trigger the button in the datagridview ?? it is quite different from the gridview in web development application.
View 2 Repliesi have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?

View 1 RepliesI have a datagridview and it has 8 columns as textboxcolumns. I am handling their cell validation with cellValidating event.
My question is that if cell validation fails for 3rd column of the datagridview then the focus should move from 3rd column to 1st column of the datagridview. How can i do this?
I have tried datagridview.column(0).selected = true, when validation for 3rd column fails, but this is not working. Focus still moves to the next cell. I can stop the focus to the current cell with e.cancel=true but i want it to move to the very first cell of the datagridview.

The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView.

Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

With an excel file opened, i'm trying to:
Select a Range of Non-Contiguous Cells within a Column, then return the address of the last active cell.
Below, is what I have so far: Note the section maked:
' I can't get the next bit to work: '
To make it work, so far :(
1. Create a new Project using VS-2010.
2. By default, the form should be displayed as "Form1.vb".
3. Add a Label (No need to name or set anything).
4. Add two buttons (Again, No need to name or set anything).
5. Double click on the Form...
6. With the form code displayed, Select all, then paste the following.
'Option Strict Off
'Option Explicit On
Imports System.IO

I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).
1. I type the first letter of the username i want in the combobox text area, the combobox drops down and shows me all the usernames starting with that letter. I scroll down to the name i want (as i scroll down, the text area holds each name but the SelectedIndexChanged event does not fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
2. I do the same as above, but instead of hitting Tab key, i hit the Enter key. The same thing happens and i get the result i want.
3. This time, i first click on the dropdown arrow of the combobox such that it shows all usernames starting from the first name. I then type the first letter of the name i want. I saw that another drop down appeared in front of the first one and it was a smaller subset of names starting with the typed letter. I scroll down this smaller dropdown to the name i want (here also, as i scroll down, the text area holds each name, and the SIC event doesnt fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
4. I do the same as #3, but this time i hit the Enter key instead of Tab key. But this time, the combobox text blanks out and the SIC event is not fired (although the name showed up just before i hit the Enter key). So i do not get any results back.
I can do the basics when I put controls on a form but this one is a little more complex. I have an application that reads in a .TSV and populates a form with controls based on the number of objects it "reads." So for instance: I have a file that contains 10 people objects and my code populates a form with controls for each person. Easy stuff..Now lets say I have a ComboBox with the items: "Alive", "Deceased", "Unborn". Right next to this I have a textbox for age. Now originally, this textbox is not enabled because the default value for the ComboBox is "Unborn". But lets say when the user selects "Alive", I want that textbox to become enabled so an age can be entered.Obviously from me asking this and the title of this question, I don't know how to go about doing this. I don't really understand events and I learn by example but the MSDN examples don't quite cut it.

My boss sent me to do this fairly interesting project via visual basic. Hes kept it fairly general though. he wants a program, that takes 2 text boxes.. and the information inputed into these two boxes are to be emailed to him when someone hits submit. He says its for keeping track of his employees even when he cant be there. How would one go about coding visual basic to take two text boxes and email them when a button is hit?
