VS 2008 Datagridview Unable To Save
Oct 2, 2009
First of all I am using vb.net(2008) and i have an application which connects to a database and is able to modify it.
My problem is that when I modify a row and try save, It doesnt save to the database although when I add a new record it does save.
Code I use to Save
Me.Validate()
Me.MessagesBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.ServerDataSet)
[Code].....
PS: When I Delete the row it works but when I try updating the database by saving it it doesnt work. Is the Database row event handler able to help my case?
I posted this in the database development section but i didn't get a reply after a day or so

I am using MS Access 2007 as database and VB 2008 to build an application to show the content of 2 tables as a single table.I have two tables in MS Access and i have linked both the tables using "ID" as primary key(1st Table),foreign key(2nd Table). I used Query Wizard to show the data of both tables in a single table(3rd Table).I am able to view the content of all 3 tables using datagridview in vb 2008(Using Code), but i am unable to add,delete,save and search the content of the table using code. My concern is,i will be able to do all these operations using codes only.Would you please help me out in this.

find items, they get added to your inventory. But the problem is is that what you have say like 3 items in your inventory, and you close the application, all the items will go away because there's no way to save. So how would I make like the program to where it saves like a .DLL file (preferably .DLL not .TXT so users cant edit easy)? Is there a way to do this like maybe when they get an item, it

I have a gridview with four template fields that I need to be able to put info into to save to the database. When I hit the edit button and my columns change into edit mode I can enter information just fine. But when I try to loop through the control to get the information it doesn't pick anything up?
Private Sub gvOLIAdj_RowEditing(sender As Object, e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvOLIAdjst.RowEditing
gvOLIAdjst.EditIndex = e.NewEditIndex
BindData()
End Sub
Here is the update event that I have so far... any ideas? Am I just not doing this right?
Private Sub gvOLIAdj_RowUpdating(sender As Object, e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvOLIAdjst.RowUpdating
Dim dts As DataTable = DirectCast(Session("BudgetsTable"), DataTable)
Dim row As GridViewRow = gvOLIAdjst.Rows(e.RowIndex)

My problem is probably ignorance as to how the DGV works, anyway, the problem.I have a bound datagridview which is used to collect user input. Data for 3 of the 7 fields is entered by looping through the rows and progmatically entering common data anfter a 'Save' Button is pressed:
For I = 0 To DG1.RowCount - 2DG1.Rows(I).Cells(4).Value = TextBox1.Text 'OperatorDG1.Rows(I).Cells(5).Value = TextBox2.Text 'DateDG1.Rows(I).Cells(6).Value = TextBox3.Text 'Time NextDG1.Update Prior to this loop I delete the last unused row if its not a new row:
DG1.CurrentCell = DG1.Item(0, DG1.RowCount - 2)If DG1.CurrentCell.Value.ToString = "" ThenDG1.Rows.RemoveAt(DG1.RowCount - 2)DG1.Update()End If
At this point the DGV looks the way it should...All fields completed correctly and no un used ro except for the new row.
After saving :Me.ItemTableTableAdapter.Update(Me.StockMoveDataSet.ItemTable)The 'Operator', 'Date', and 'Time' are not saved to the database for the first row only I have tried EndEdit, Update, refocussing the currentcell/row all to no avail.

I created a database in access 2007, linked it to my project in visual studio 2008 (vb). When I enter some data using the UI, it does not save it in the database, and it's gone as soon as I run the program again. I dragged the textboxes from the datasource panel, onto the UI..
this is the code that was automatically generated by vs for the save button:
Private Sub StaffBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StaffBindingNavigatorSaveItem.Click
Me.Validate()
Me.StaffBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.GartisDataSet)

I'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.
[Code]...
I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

I have an asp.net web forms application. In this application, students upload assignments and submit a survey along with it. For the survey, I read values from DB and dynamically generate ASP.NET Controls like radiobuttonlist, checkboxlist, textbox on the form during gridview's RowDataBound Event. I cannot do it in Page_Init method because I create only if a user click on a specific assignment which requires a survey to be submitted.
When I submit the survey form, the survey values are not saved into database. During debugging I figured it out that the values are not available in the codebehind page. The radiobuttonlist.selectedvalue returns and I get following error[code]....

My application uses 3 DataGridViews in asingle Windows form. The 3 are never visible at the same time, and I have a sityation that I cannot figure out. The first examole below works perfectly:
For Each row As DataGridViewRow In dgvBooks.Rows
If row.Cells(4).Value.ToString = "YES" Then
row.DefaultCellStyle.ForeColor = Color.Red
[code]....
The only difference in the 2 blocks of code is the name of the DataGridView. I'm at a complete loss to figure out why one works completely and the other only partially. I have checked the execution, one step at a time and everthing happened at the right time and accurately, The upper case string is correct as is rhe index designation of the field, and I'm lost for a reason.
