I 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

View 2 RepliesI've built a reporting feature in my app that uses a DATAGRIDVIEW to show the results of a stored procedure execution.I've noticed that the datagridview has some nice features - like the user can re-order columns.And I allow them to re-run the report and the "re-execution" nicely fills in the DGV - even if the columns are moved around.Problem is that I also allow them to run different reports - and that column re-ordering and other "retention" features of the DGV are bad.Should I be creating a DGV in the IDE and then cloning that somehow at runtime for each report that is run. As long as they are re-running the same report then I can re-use the DGV like I am now.But if they select a different report then I dispose of the DGV and make a new one.
View 2 RepliesBelow is the code to create a single Editable ComboBox column in a DataGridView on a form. I believe I have follwed the instructions to allow the user to input new values other than those in the list, however if you create a new project and add a button and a DataGridView control onto the form, then copy and paste this code and run the program, you will find that you cannot type any character in the edit box other then characters that exist in the list and only 1 character will be displayed at a time. I have set the Autocomplete value to 'False' and setting it to 'True' at least allows me to type more than 1 character but still not any strings that don't exist in the list.You can even remark out or not use the entire Call Validating sub routine to see the issue of not being able to type in the cell.

View 1 RepliesMaking a comeback after five years, I am greatly impressed by the functionality of the DataGridView.It seems to me that the most obvious omissions are:
1) numeric columns, numeric up/down columns, date columns, list box columns;
2) printing a DataGridView;
3) binding a DataGridView to a database table when the database is selected at run-time. I see that several software houses offer products to complement the standard Microsoft DataGridView feature, all of them at a hefty price. I am satisfied with the RustemSoft product's DataGridView column features but it does not seem to offer any help with printing.Before I spend another $80 on DataGridView software, I would like to find out whether free coding is available for cut-and-paste or download. Maybe these features will be included in the next version of VB.NET but I cannot wait for that.
I am attempting to refresh my datagridview but it does not seem to work. I have a separate frm where people insert data, and then I have a button on the main frm where people can click refresh once the other frm is closed. I click refresh and yet the data does not update in the datagridview

I am using VB.Net 2008 and have build a windows form with a datagridview that displays a query of records for the current client. One of the columns is for Fee. I need to total that column and place the result in a Label or Textbox. I am using the Query builder to pull the records and so I can not get away with the SQL expression in the query returns the Schema does not match error. I have tried to code it pulling the information directly into the form from the Datagridview and could not make that work either.
View 1 RepliesI just want to simply be able to edit a database directly using a Datagridview. That includes adding new rows, editing existing ones, and deleting rows. So far if I have been able to get one of those actions to work, the others do not. I found the codebank entry by JMC and I am trying to use it to connect to my database. I have a bindingsource, a dataset, and tableadapter created via the designer. Now I need to figure out how to combine all these components.
VB.NET
Imports System.Data.SqlClient
Public Class Form1
Private connection As New SqlConnection(My.Settings.Database1ConnectionString)
Private adapter As New SqlDataAdapter("SELECT ID, Name, Quantity, Unit FROM StockItem", connection)
Private table As New DataTable

I am trying to identify the value if a checkbox against a record in a datagrid.
I am trying this:
Dim eRow As Integer
eRow = dgv.CurrentRow.Index
TextBox1.Text = dgv.Item(6, eRow).Value
But I get nothing it works on other fields in the datagridview. The user will de-select records he does not want to authorise. When he has done this I want to update another table with the values that are selected(or True) on a button click event. There could be 100's of records so not sure if this is the best way to go about this.
Right now when I need to refer to a cell to update the text I do it this way:
DG1.Rows(intRow).Cells(1).Value = "Hello!"
Is there a way to use the column name for column #1 rather than the number? This way if I decide to add columns later in an update and it's not at the end of the current columns, I do not have to re-number all my code. I tried searching but must not be looking for the right keywords.
like to be able to add up (and insert) all the values of a column in the datagridview but can't work out how to do it.I would like to insert a value into the ApplicantID column and read a value entered in the Grade column when a button is clicked

I haven't yet tried, but would the data append to the dgv if i just called this again using query and removing the queryTotal variable? seem to think they behave like that from past tests?
If I have a datagridview's datasource set as some datatable, is there a quick and easy way to reflect the changes in the datatable that have been made in the datagridview?
When I sort my datagridview, the rows in the datagridview and the datatable no longer match up.I know I can catch when the dgv is sorted and for-loop through the dgv and send it to the datatable, but I was hoping there was a save/update method or some such thing.
working with DataGridView and MSAccess. I have 3 combo boxes that will give me the search data to use to fill in the DataGridView box. I am only showing 3 items in the DataGridView. Can someone lead me to some code I can use to help me setup the query or code I need to fill out the DataGridVeiw box based on the 3 items I have.

How can I modify this:
vb
Content.Font = New Font("Verdana", 8, FontStyle.Bold)
So that in my datagridview it only makes the selected row bold when it is double clicked?

row = e.RowIndex

When I double-click on a row in a DGV I first have to single-click the row to select it before the CellDoubleClick event will fire. Is this the normal behavior? Is there any way to just double-click any row & have the event fire everytime
View 2 RepliesI'm using a DGV to show some data & I'm using the CellClick event to run some code when the user clicks on each row. But I also want to run some other code if the user double clicks a row, but the CellDoubleClick event never fires, the CellClick event just fires twice. Does anyone have any ideas on how to make both events work?
View 1 Repliesi have a datagridview(has about 7000 rows) like this:
ID Name
9 David Brown
11 David Blue
17 Hans Yellow
what i want to do is when i write something in a textbox, i want to show rows only which starts with my text.for example, if i write "dav", then first 2 rows should be visible.
Im looking for an event that fires after a user enters a tabbed page and after the datagridview on that tabbed page is painted. BUT only fires on the load, not every single time the datagridview is painted. I am making rows in the datagrid invisible to the user based on wether or not a checkbox in the row is checked.
If I do this on the Tab_Enter event it paints the datagrid before I can loop through the records and change the visible property And if I do this on the Datagridview_Paint event it fires everytime the datagrid is painted (I only want it to fire once)

I'm filling up a datagridview from a datatable which is populated by sql queries.
So the idea is to display all the items in an order.
Now as we scan each item, i want to change the textcolor/backcolor of the row that lists the item scanned.
any inputs on how this can be done?
Is there a way to manually select a row? Right now, it uses the default selection method where when you left click it highlights the row, but I would like it so when your right click on a row it also selects the row, because I would like that row to be active when the row is right clicked, and not just left clicked.
