Transfer All The DataGridView Rows From From2 To Another DataGridView Of Form1?
Mar 13, 2011
I have 2 forms, each one with a datagridview.I want to transfer all the DataGridView Rows from From2 to another DataGridView of Form1. but it's not possible.
In VB.NET 2008 I've two forms 1 & 2 containing two datagridviews connected to two data source 'ACCESS 2007 tables' Now I want to select multiple rows from one datagridview (form1) & transferring these to another empty datagridview (form2) with a button_click.
I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click 'Function declarations
In the FORM1, the datagridview contain some product column and user can input the number of product quantities they want to buy.if user press the "buy" button, i want it to open FORM2, with datagridview containing the list of the product they buy from datagridview in FORM1.[code]...

I want to import a portion of an XML doc into a DataGridView. Is the easiest way to do this to read the XML into a DataSet using the DataSet's ReadXML Method?

How can I transfer the data from the Specified cell of the Datagridview to texbox.. For example I click on the specified Datagridview cell, I have a 3 columns Name,Username and Password.

It's like that the columns in the Datagridview were binded into the textboxes once I click on it..

I have 4 DatagridView's. I want to take the data from 1,2,3.. and then place it on 4. (I am adding some images). The Names in 1,2,3.. Should correspond with that is 4. SO ,,that means i want to accumulate the totals of each player and place it in the final DataGridView.
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
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
In my scenario when i press the "Get Book Details " of the Form1 , it will redirect to the Form2 , in the form load of Form2 a datagridview is filled with values along with the checkbox column and the desired rows of all the columns are selected and when OK button(form2) is pressed the selected rows should get populated to the datagridview of the form1.But i m not getting the selected rows to the form1t.

'form 1=userpage.vb Dim objuserpage As New userpage() ' form 1 textbox TextBox1.Text[code].....
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.
It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2 Column3 Column4 1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
when i press enter key then column value is incremented and i want that when i reach to column index 4 then a new row is created in datagridview and again this keydown event is executed and agin when i am in second row in gridview again a next row is created when column index is 4 so how to that .
through this code only i can move to next col when i press enter and i have made DataGridView1.AllowUserToAddRows = false
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown If e.KeyCode = Keys.Enter Then
My datagridview is bound to a data table. I want to filter the datagridview without affecting data table. I know one way is to use bindingsource, but binding source will use column names in its filter. But I want to enable users to enter any string in a textbox to filter. So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview. But the problem is that when datagridview is shown on the form, it is unchanged, the same as the data table. I do not understand why rows are not removed on datagridview The code is as follows:

I keep finding ways to clear all the rows of a datagridview... but i want to keep my rows..is there an easier way than looping through every cell to clear all the values out of the cells of the datagridview??
