I have an Access database that is updated directly in Access. I'm trying to write a program to 'monitor' the database, and have a DataGridView control showing the contents. When the program is first started, it shows the current data in the DB fine, however, I've been unable to get it to refresh with any updated data from the mdb file. I have a timer running on 5 second intervals, and if i clear the dataset, the DataGridView refreshes to empty.

I have a UserControl inside UpdatePanel, how to update the user control when clicking a button
View 1 RepliesI have a form where the user will choose multiple clients from a subform that has a DGV.Each row has a checkbox indicating that it has been selected.When the user is finished selecting the clients, I need to store the selected clients ID Number, Name, and Program Number either in a temp table or another method to only handle about 30 records.After that part is done, I need to create a new tab for each client which has a UserControl on the tab. I have the new tab thing working but I need to learn to apply the client to the first new tab/user control then create another and so on.

i am editing the data of access database through datagridview.after adding data the data that i have edited dat is not being edited in datagridview.
how to refresh datagridview so dat the edited data can b shown without reopening the form.
Well, the title pretty much says it all. I have a user control that is a a collection of six label controls. three are used as visual color indicators, and the other three are used as the corresponding value for each color indicator. (It's sort of like a legend key on a chart or map.) I have created a custom class to store the three values, and the associated methods to interact with the values. (I can probably use a structure instead of a class, but right now, I don't want to discuss that.) My problem, is that I want to show my user control inside a cell of a DataGridView. I've looked at the examples that create a MaskedTextBox DataGridViewCell, but I can't seem to get it to work. Here is what I have:
[Code]....
Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
If e.ColumnIndex <> 3 Then
Exit Sub

I am using the CellClick event to update DB column PaidStatus from Paid to Un-Paid and vice-versa....Once updated i want the updated data to be reflected..i am using DataGridView1.Refresh()....but it does not show the updated data from the DB..i have to close the application and re launch it to see the changes.
I created two tables(FIRSTtable and SECONDtable) in the mysql database and two tables that are related.[code]...
Relations between the two tables using the product_id column with UpdateCascade and DeleteCascade. Both relationships are functioning normally when I try with the sql script. Suppose I delete all product_id in the FIRST table, all existing data in the SECOND table will be deleted.
Both of these tables displayed in datagridview. When I delete all the data in the FIRST table, the all rows in datagridview FIRST table will be deleted, also the data in mysql the FIRST table will be deleted.
I try to open the mysql database, the data are in SECOND Table also deleted, the problem why the view that in the second datagridview, can not be deleted, still keep the previous data? How to refresh datagridview binding in vb.net or C#? [code]...
i use a button to execute the update command for editing the row of the sql table. The row is update when i click the button, but the datagridview is not show the update of that row automatically, so i want to know how to refresh the datagridview when the table is update by just clicking a button.Here is the code below i use for editing the row :
Private Sub editbtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles editbtn.Click
If serialnotxt.Text = "" Then
MsgBox("please enter the enter serial no and click search")

View 5 RepliesI have a vb.net form with a dataGridView
The dataGridView data source is the dgvTableAdapter with this sql statement
SELECT membres.ID, membres.refere_par, bands.titre,
membres_1.prenom & ' ' & membres_1.nom AS reference_nom
FROM ((bands INNER JOIN membres ON bands.ID = membres.[band])
INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)
[Code]....
I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.
The membres table is an access table
I'm running the app in visual 2010 debug mode.
I have a problem with a datagridview control, when first loaded with existing data it shows the correct rowcount figure.However, I have a function that when invoked triggers an oledbcommand to clear those records from the database (access) and load new ones from a file (excel/text).The oledbcomands work fine, and the gridview refreshes with the new data fine. However, the rowcount after this refresh is always 0, even with records. What I am doing is creating a module for my app that allows the user to specify the column title and types for a file import - and the procedure will read the header row from a txt/csv or excel file automatically.[code]If I just make edits in the datagridview (as in not invoke the above) the rowcount returns properly.If I close and re-open the form the new data appears, and the rowcount property returns fine also, but I don't really want to have to tell the user to close and re-open it before making any changes.I must be missing something on the refresh or with the datatable or adapter side of things.
View 2 RepliesIn a windows form I do have a datagridview. When a user pushes the button, the underlying datasource of the datagridview (a dataview) changes and the new content with new columns is shown. This works fine, only problem is that the header-height differs and that the datagridview does not properly display the smaller headers until I click into the first datarow of the datagridview. Simply using the .refresh()-method of the datagridview after assigning the new datasource does not seem to work.
Here is a little code-snippet showing how I assign a new datasource to the datagridview.
Dim view As DataView = myDataTable.DefaultView
With Me.MyDataGridView
.Columns.Clear()
.AutoSize = True
.DataSource = view
For Each col As DataGridViewColumn In Me.MyDataGridView.Columns
col.ReadOnly = True

I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.

View 11 RepliesOn my Winforms app, I have a primary form with a DataGridView bound to a database Entity datasource.
The grid is set up not to allow inserts. Instead I have a button on my form that kicks of a second dialog where the insert takes place (ie. with friendlier ui than is possible with the DataGridView).
The insert is working fine.. query of the underlying table in db shows that the record has been inserted. However, I can't seem to get the DataGridView on the primary form to see the new data just created by the second dialog.
I have read many Stack Overflow q & a's and tried various solutions to get the DataGridView to refresh to show new data.. but nothing works.
This must be a common situation ?? Can someone suggest some VB.NET code that will work ?

I 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 ?

I have a datagridview in Visual Studio 2008. I am using the binding navigator to add rows to the grid. I have two text boxes on the form that I am using as the data entry method. I have dragged these onto the form as details items from the dataset and placed them below the datagrid.
I hit add item item on the navigator, fill out the test boxes and then hit the save button on the navigator and it sends the data to the database but is doesn't not update the datagrid. The only way that I can seem to correctly display the new row is to use the Datagrid fill method

I'm noticing that sometimes strings drawn in a given column or row will be slightly over-antialiased or altogether clipped after scrolling horizontally or vertically.I can see that the quick way to clear this up is to send a final .Refresh() call to the DataGridView after completing the scroll. But, unlike the ReSize event for Forms, there doesn't seem to be a Begin and End Scroll event for controls, so I can't just send a .Refresh() to the DataGridView after scrolling.Does anyone have an idea how I might go about detecting when a scroll event has completed so I can send that final .Refresh() to the DataGridView?
