View 2 RepliesDatagridView Containg Combo-boxes Can't Refresh
Dec 5, 2011I have a datagridview bound to a bindingsource. This datagridview contains one column which is a combo-box.
Upon a click on a button,I change the underlying datasource. The selected values of the combo-boxes change.
But the change doesn't appear on the screen ! To make the changes visible (refresh each combo-box), I have to hover on the datagridview with the mouse or use the scrollbar !
Question 1 : why do I see this ?
Question 2 : what should I do to make the changes immediately visible ?

View 3 RepliesDatagridview Bound To A Datatable Setting Its Datasource Property To The Datatable
May 20, 2011I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
Forms :: Set The Column Names In A DataTable As A Datasource To A ComboBox?
Aug 4, 2011I'm trying to setup a form to search for data within an existing DataTable.
FilterColumnsComboBox.DataSource = WOTable.Columns?
FilterColumnsComboBox.DisplayMember = ???
FilterColumnsComboBox.ValueMember = ???
[Code]....
I could hard-code in the column names ("WO_Number",WO_CustID","CustLastName", etc...), but would prefer to pick this up dynamically (partly because I want to reuse this code later).
SQL SELECT With Multiple Tables To Datatable/DataView Get Table Names
Feb 21, 2011For my app users can enter a SELECT statement themselves. This can be any select statement at all, it will be mainly used for creating a quick view e.g. SELECT * from table1 LEFT OUTER JOIN table2 on table1.id = table2.id.
Whatever this select statement maybe I load it into a datatable (after checking for no nasty stuff of course) in vb.net. I want to know the table names so I can query the database again for validation purposes on things like datatypes etc.
da.SelectCommand = New SqlCommand(sqlStatement, tempDB.Connection)
da.MissingSchemaAction = MissingSchemaAction.AddWithKey
dt = New DataTable
da.Fill(dt)

Add Data To A Datagridview That's Not Displayed?
Dec 15, 2011I'm writing a program for my job in which we are keeping track of employees usage of food at work. The form in question interacts with an access database to a binded control with labels and textboxes. This form I'm working on is the user view which doesn't allow them to input their username, I have the user name saved to a variable but it will not display when I the add a new record. I tried many things but I'm just getting frustrated.
Is there away to add data to a row that is not displayed on the screen in a textbox for the user to see? There are 3 different "cells" (textboxes) I want to be filled in by other code without the users knowledge.
I'm currently using MSAccess 2010 and Visual Studio.net 2010
Datagridview Displayed FirstDisplayedScrollingColumnIndex?
Aug 14, 2009I have a datagridview with 3 displayed columns and 10 columns overall. If I run the program the gridview start with the first column visible and displayed. Now i want to scroll with the vertical scroll bar.
If i click on the "right" button of the scroll bar
my DataGridView1.Scroll - event
says:
DataGridView1.Columns(0).Displayed=True
DataGridView1.FirstDisplayedScrollingColumnIndex = 1
So this means "yes, the first Column is displayed but the first displayed Column is the second one!"
This doesn't make sense to me. Is there another opionion to this Problem, or is this just a small bug?
I use Visual Studio 2008 Pro (Visual Basic) with .NET Framework 3.5.

DataGridView Is Displayed With Four Columns?
Jul 18, 2010I am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.

View 6 RepliesDatabase Is Selected And Displayed In A DataGridView?
May 11, 2009I am using a DateTimePicker to allow the user to select dates between which, info from a database is selected and displayed in a DataGridView.This works fine exept that the dates selected by the DateTimePicker seem to bring back results in US date format!
If I do a debug.print (DateTime1.text), the date is in UK format i.e 11/05/2009 but when these variables are used in a Select statement, the dates returned seem to be in US format e.g. selecting dates between 01/04/2009 and 7/05/2009 selects dates between 04/01/2009 and 05/07/2009 when the results are displayed in the DataGridView!

Get Datagridview Table Row When Datagridview Datasource Is DataTable?
Dec 8, 2010My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"
