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)

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.

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

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.
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!
if could modify the following code for me so that it save data row by row from a DataGridView into SQl Server. Currently, the code saves data from all rows at time instead of saving only the recently added data in a row or rows when the user clicks a button.[code]...
View 1 RepliesHow 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

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've been all over the internet to solve this problem, but i've found no solution to my problem.my concept is this.Based on selected value within a combo box, the datagridview will populate with values from the database.

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?

Access <asp:table> table rows added by javascript in asp.net webform . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.If I have a <HTML> table or an <asp:table> control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?
I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.there was a way to include these new rows in the post-back, the same as any client-side user input?
I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like:

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
when populating a data grid i keep getting a redundant row in the bottom. is there a way to lock grid rows to the number of rows in the data table?
View 1 RepliesI have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):
'Sub table 1
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung
[code]....
p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:
xx| C201,C213,C606,C619 |02300877 | Samsung
xx| C201,C213,C606,C619 |02300877 | Toshiba

I am currently using DevExpress 10.2 within Visual Studio 2010. In a previous question I was trying to print the current user view of a DevExpress GridControl with the user's choice of expanded or collapsed master rows and/or group sections. I was told this was not possible at this time. I have now decided to use the following code:
[Code]...
Public Shared Function isMatch(ByVal username As String) As Integer
For i As Integer = 0 To table.length - 1
Dim cellValue As String = table.getRow(i).getCell("Alias")
[Code].....
I have the code listed above as a translation from a Java snippet. The problem i have is that in Java, my table was stored as a dataset and as such, the methods were easily identifiable by "getRow" and getCell" using specific numbers and column names. However in VB the information is stored in an MS Access database (which i already have an open connection to, called: "_SalesPerformance_AnalyticsToolDatabaseDataSet12") and as such i do not know the correct way in which to iterate through each row in the database, checking a specific column against an already specified variable and then returning an integer based upon the value of a seperate column in the same row.
I have an Excel sheet that looks like this.
View 1 RepliesDim _tableBackLogs As System.Data.DataTable
Do While i - 2 > 0
_tableBackLogs = Global.DataAccess.GetDataTable("SELECT SubjectID,SubjectName,Grade FROM SubjectPI WHERE RegNo='" & CInt(HttpContext.Current.Session("userName")) & "' AND Status='Fail' AND Semester='" & i - 2 & "'")
i = i - 2
Doing this replaces the previous data in the DataTable. I want to retain the previous data i.e i want the new rows to be added to the DataTable w/o replacing the previous rows.
My DataGridView sorts by date. For grins I entered the date 11-02-2010 fully expecting it to be at the bottom of the list, not listed right after the last 11-02-2009 row and before the first 11-03-2009 row.How do I handle this so that come January 1, I won't see all the 01-01-2009 rows listed first followed by the 01-01-2010 rows then the 01-02-2009 rows, etc?

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".
I have added a column to a Datatable called CallsPerDay which is there to tell me how many telephone calls have been made on a particular day or days.Is there a datacolumn.expression which will allow me to Filter on the day, count the rows and then populate this added column with the result.
