Load Data Into DataGridView?
Mar 15, 2012
My code is working fine I just need a way to reset the DataAdapter1 into 0 (like reset) So if the user hit the button search 2 times to shows up only 1 time the elements of database "product".. If i used the code below and hit 2 times the button the DataGridView show 10 product for examplat the first time and +10 for the second, a total of 20 products, even if I search then edit a product and search again it's fixed the previous table and prints again 2 times the table....
DataAdapter1.SelectCommand = Sql2 ''database load
DataAdapter1.Fill(ds2, "products") ''dataset
DataGridView1.DataSource = ds2
[code].....

I was wondering if there is any way to load data from excel sheet into a datagridview in VB2008 dynamically. I have looked at few data connection codes but all of them involve the excel sheet and thw workbook name. Is there anyway that I enter the excel sheet name in a inputbox and the data from excel loads into datagridview without hardcoding the sheet name. I know data can be imported using the below code, here the programmer has to mention the excel workbook name, path and sheet name. [code]I am developing a program to perform some calculations and my data is in a number of excel workbooks and worksheets. I need to be able to bring the data from these excel sheets into the datagridview to perform calculations. So I was thinking if I could mention the excel sheet name in the GUI and then accordingly the data from that particular sheet would be loaded into the datagridview to perform calculations.

All I want is to update the selected row data in form1 to another form2
Form1 Objects
Form1 = MainAppForm
DataGridView = DGVMain <= binded
Button = btnUpdate
Form2 Objects
Form2 = frmUpdate
Button = btnSubmit
15 textBoxes = you can see its name in the code below and all of them are data binded
MainAppForm Code
Pass the selectedrow data to form2 (frmUpdate)
Private Sub btnUpdateDouble_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
If DGVMain.SelectedRows.Count = 1 Then
Try
frmUpdate.ItemIDTextBox.Text = DGVMain.CurrentRow.Cells(0).Value.ToString()
frmUpdate.PartTypeTextBox.Text = DGVMain.CurrentRow.Cells(1).Value.ToString()
frmUpdate.PartNameValueTextBox.Text = DGVMain.CurrentRow.Cells(2).Value.ToString()
frmUpdate.PackageTypeTextBox.Text = DGVMain.CurrentRow.Cells(3).Value.ToString()
frmUpdate.QuantityTextBox.Text = DGVMain.CurrentRow.Cells(4).Value.ToString()
frmUpdate.UnitTextBox.Text = DGVMain.CurrentRow.Cells(5).Value.ToString()
frmUpdate.DescriptionTextBox.Text = DGVMain.CurrentRow.Cells(6).Value.ToString()
frmUpdate.LocationTextBox.Text = DGVMain.CurrentRow.Cells(7).Value.ToString()
frmUpdate.ProjectBoardTextBox.Text = DGVMain.CurrentRow.Cells(8).Value.ToString()
frmUpdate.CommentsTextBox.Text = DGVMain.CurrentRow.Cells(9).Value.ToString()
frmUpdate.OrderCodeTextBox.Text = DGVMain.CurrentRow.Cells(10).Value.ToString()
frmUpdate.CurrencyTextBox.Text = DGVMain.CurrentRow.Cells(11).Value.ToString()
frmUpdate.UnitPriceTextBox.Text = DGVMain.CurrentRow.Cells(12).Value.ToString()
frmUpdate.SupplierTextBox.Text = DGVMain.CurrentRow.Cells(13).Value.ToString()
frmUpdate.ManufacturerTextBox.Text = DGVMain.CurrentRow.Cells(14).Value.ToString()
frmUpdate.Show()
Catch ex As Exception
System.Windows.Forms.MessageBox.Show(ex.Message)
End Try
ElseIf DGVMain.SelectedRows.Count = 0 Then
MsgBox("Please select one item to update!", MsgBoxStyle.Information, "Update")
Else
MsgBox("Updating multiple Items is not allowed!", MsgBoxStyle.Information, "Update")
End If
End Sub
Form2 Code
I want to update the data by this code, but it refresh only the data in Form1
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Me.Validate()
Me.SparePartsBindingSource.EndEdit()
Me.SparePartsTableAdapter.Update(Me.InventoryDBDataSet.SpareParts)
'Refresh
MainAppForm.SparePartsTableAdapter.Fill(MainAppForm.InventoryDBDataSet.SpareParts)
End Sub
No problem in updating the data if I put the code below in Form2 load event
Me.SparePartsTableAdapter.Fill(InventoryDBDataSet.SpareParts)
but the problem is, it will refresh all the data in the Form2, and my code in Form1 becomes useless.
Thanks in advance!

easy way to simply load the data from database into a datagridview with one of the columns being a comboboxcolumn. Apparently there is no selectedvalue, selectedindex or value as in a combobox to return the combobox value. What I need is to verify if the database value is 'true' and if it is then I need to set the comboboxcolumn with a specific value.
Ex:
if ds.tables(0).rows(0)("flag") = "true" then
datagridcolumn.selectedvalue = 1
else
datagridcolumn.selectedvalue = 0
end if

I have a DataGridView that I'd like to load with data that I'm retrieving from a SQLDataReader running in a background worker as the data comes in (it's a query that takes a long time). My goal is for the user experience to be similar to searching for a file in Windows where the results appear in the list as they come in and you can still interact with the window.
I have it working with a background worker and data reader and I'm trying to add the row from the SQLDataReader.Read through using the BackgroundWorker.ReportProgress method. Everything technically works but the flicker is crazy and the form is unusable (probably not because the GUI thread is blocked but just because there's so much going on...) How do I make loading the datagridview "smooth"?

I have searched the web and this site for an answer but have not been able to solve this problem.I am not able to place a flashing cursor in a specified cell of a data bound DataGridView on Form_Load.My test project consists of a single Visual Basic 2008 form with a database created in Microsoft SQL Express 2005 using the Add New Data Source in the Data Sources window.The database has one table consisting of 2 columns.Column 1 being the primary key with Identity Specification set to On.The second column is a VarChar50.The DataGridView was placed on the form by dragging it from the Data Sources window thereby creating the Binding Navigator and the Private_Sub Form_Load code.I have added the code that should put the cursor where I want it.[code]
