How do I capture the cell value of an entry in a new row in a datagridview? This is what I have so far but it's capturing the previous row's cell value:
Me.DataGridView1.CurrentRow.Cells("License").Value
Im new to VB programing and Im using VB 2008 Express. I have set up two forms (Main and Edit) and I have a datagrid set up on each form. I can make changes to he DB on the edit form, close it, and the main form is updated with the new info. All is well except that Im also trying to enter data directly into the cells on the DataGrid on the main form and I cant. I can select the cell and it highlights it but it wont accept any characters.
View 1 RepliesI was thinking get the row index and then the cell index and using that to get the specific cell I need somehow but I do not know how to get the specific cell, so would this be easiest if so what command would I use to get the information from the cell, if not how would a better way to do this be?
I cannot find the way to get the row index if one exists so I am guessing it does not exist with this method so how would I go about getting the information from a specific column of a selected row?

I am using a DataGridView, which is bound to a dataset. There is a bindingNavigator as well.
when a user deletes a row by clicking "bindingNavigatorDeleteItem" button, I am trying to get the row being deleted.
private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
{
int crow = gridEventType.CurrentCell.RowIndex;
but it returns the newly selected row AFTER deletion of a selected row.
so, If I have two rows
0
1
2
and I delete 2
crow is 1, not 2.
Am I missing something here?
2. How do I know whether certain rows are modified in datagridview?
I have a datagridview (unbound). Fields are Name, Family Name and Phone No and a checkbox colum.
There are ten rows in that DataGridView.
There is an OK button
I need to get message of showing which rows user has checked. The message should appear when user clicks OK button. There could be several message, checking each row one by one, in a loop.
I am not able to get this message. I tried following code in OK button
Dim strCB As String = dgvChooseQs.Rows(0).Cells(3).Value.ToString
Cell(3) is my checkbox. Donot consider Rows(0), at the moment I am just checking value at row 0
I have read and tried a dozen or more examples of trying to capture the Enter key in a datagrid, but I have yet to find something that works. My scenario is :
ds.Tables.Add(dt)
dt.Columns.Add("Inventory Nr", GetType(System.String))
dt.Columns.Add("Cases", GetType(System.Int32)) Inventory Nr in the next row.
[code].....
Have 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.
[code]...
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."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

Is it possible to disable cursor moving from cell to cell in datagridview?

Part of the project needs me to capture data, for example, email address, from certain rows/columns of a datagridview and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). I am familiar with doing these in web form but windows form are different and i am not familiar with it.

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.

View 2 RepliesI have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

If I wanted a character in a datagridviewcolumn replaced when it's typed, not when the cell is left, how could I achieve that? Is there an eventhandler tied to that?
View 1 RepliesOkay, I've got a datagridview in my WinForms app that auto-builds the column list from a datatable schema. It's working fine, except that it allows the user to enter values too long for the database field. For example, I have a "name" field that is defined in the Sql-Server database as a varchar(50). Is there any way to limit that cell (column?) so that it only accepts 50 characters? Right now it lets them enter anything and throws an exception later.

View 1 Repliesi am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.
What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.
View 2 RepliesI am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:
1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?
2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).
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).

I wish to have a list selection inside a cell of it. like when the cursor is placed in a particular cell and the user hits 'Tab' button in keyboard a list of names & no should be listed and they have to select a particular name, click a particular row in the list form, which in turn needs to fill the cell with the name value.m
