Programmatically Moving Trough Rows In A Datagridview?
Jul 14, 2009
I have a button on the screen 'Next' which performs some activities, but at the end I want to move to the next row in a datagridview to show the user what record they have moved to. I expected this to be easy, using the following code:
Dim CurDGVIndx As Integer = DataGridViewPtList.CurrentRow.Index
DataGridViewPtList.Rows(CurDGVIndx + 1).Selected = True
BUT.... Yes the highlighted record is the next record using this, however the selection (where the little arrow indicator is) stays on the original row. The selector needs to move too!
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."
how to add Rows programmatically to the DataGridView's rows collection when the control is data-bound? here is my code but i got error as "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound? "
I have a button 'Next' which performs navigation, but at the end I want to move to the next row in a datagridview to show the user what record they have moved to. I expected this to be easy, using the following
Dim x As Integer x = dg.CurrentRow.Index dg.CurrentCell = dg.Rows(x + 1).Cells(0)
At end of last record it show Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index + visual basic 2008
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.

I need to highlight rows in an unbound datagridview at runtime.I've tried to highlight right after adding the row using dgv.Rows.Add(row0)dgv.CurrentRow.Selected = True
This has no apperent effect as none of the rows are highlighted.How do I get various rows to highlight at runtime.
Below: datBrakePointsX.Rows.Add(strA) produces the error 'Rows cannot be programatically added to the DataGridView's rows collection when the control is databound.' To my knowledge, this is an empty grid. I am adding data manually and the code below works if I remove the line. The problem is I need to add the next line.
Private Sub cmdAddX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddX.Click ' Find the first blank cell For c As Integer = 0 To datBrakePointsX.Rows.Count If Len(datBrakePointsX.Rows.Item(0).Cells(c).Value) = 0 Then datBrakePointsX.Rows.Item(c).Cells(0).Value = c [Code] .....
I have DataGridView display Customers Details. The DataSource are from DataSet. After the user have created a new customer record and updated the SQL SERVER Table, Instread of refreshing the whole DataGridView I am trying to add new rows with data from the TEXTBOX into the DataGridView and it generated this error message: Rows cannot be programmatically added to DataGridView's row collection when the control is data-bound This is the coding which the error was generated from:
Private Sub FRefreshDataGridViewRow() 'use strmode to determine New or Edit existing record Dim strCell1 As String = CType(Me.txtCustId.Text, String) Dim strCell2 As String = CType(Me.txtCompName.Text, String)
I have a live database and an Archive database. I want to do a selct on the live and basically create a new row in the archive database table and insert all the columns then delete the row from the live. Here is the code that creates and deletes:-
Private Sub MoveToArchive(ByRef oleDRClean As DataRow, ByRef oleDSArchiveCleans As DataSet) Dim oleDRArchiveClean As DataRow oleDRArchiveClean = oleDSArchiveCleans.Tables(0).NewRow
[code]....
I ran a query in access to show the same sql select and after running my routine they all say #deleted. But when I run the query again I get the rows back WHY!
ames tile1 to tile 100Array is loaded from a textfile of 10,10 (not stored as a 10,10 just parsed from line to line, which I feel needs to be changed asap)Each tile is then given a corresponding graphic (e.g. grass, water, lava) and soon hopefully I will add interaction with certain tiles
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 my datagridview table, i have two status, which is "paid" and "parked". I want to display both but i want to freeze the state or disable rows if the status is paid.However, as i was doing that i found out that the property for state is read only. Have you encountered such? Is there another way to do this?
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.
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:
[code]...
There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
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 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.
I have a form created which an unbound datagridview that has three columns. "Position", "ID", "Name". The data is being added at runtime into a database upon the forms completion. (I don't want to add unnecessary rows to the database in the event a person clicks Cancel.) What I need to do is on the deletion of a row in the datagridview, search through the rows "Position" for a "HJ" value. If it's not found, change the "Position" value of the first row to be "HJ".
I have a datagrid control on my form that receives data from a device on the COM port. I strip out the data I need and put it into the currently selected cell. When I load the grid, I find the first empty cell and set the focus so each load presents the user with an empty cell to start receiving data. Once I get the measurement, I need to move to the next cell down (like hitting enter in the grid). This will allow the user to do measurements with the external device without having to move to the next cell.
Problem: My datagridview is moving from a tabcontrol onto the main form when I execute the below code. I desire it to stay in the original position. Details:
1) I created a MAIN datagridview1 for my master on tab 2 (OK) - this is for editing, deleting etc.
2) I created datagridview3 on tab 1 for implementing 2 textbox filters (OK)
3) The actual filter code fires on changing of values in two text boxes
The above works perfect except when the code below is executed, datagridview3 moves from tab1 of my tabcontrol to my main form. How do I keep it from moving (desired) or at the least move it back to control tab 1?
I am updating my last post so hopefully someone will help. I have following code that will move a cell to the next column when hitting the enter key while doing an edit. It will even check the row at the last cell to validate data is present.
However, if there is no data in a cell and I press enter, the focus moves to the next line like it normally does. I need to prevent the user from moving or clicking on any cell until the cell they are on has data in it. Here is the coe I have used[code]...
