View 2 RepliesUnable To Save All DBV Rows To Database?
Feb 6, 2009My 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.

View 1 RepliesSave Datagridview Rows As New Rows?
Apr 26, 2012It 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.

View 1 RepliesAdd Additional Rows To Dataset?
Jan 26, 2011I have a parent/child relation I am trying to create fow 2 datasets.The parent ds consusts of a range of PO Header information
After I fill this dataset I loop through it getting the PO number. I then take that value and execute another sql statement on the DETAIL file and fill a dataset(dtlDS) for EACH row in the parent. How do I add to this dtlDS for each row? I am getting no CHILD data in the merge. Should I be filling to a datatable and do an add.row and THEN dump into the dtlDS?
Asp.net - No Rows Being Returned From Dataset JUST On IOS Using MVC 3
Aug 11, 2011I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view. I am using jquerymobile to render the view for the iOS devices and have taken that out of the mix to test and it still doesn't work.

Dataset - Print Out Rows From A Datatable In .net?
Dec 31, 2011I am new to vb.net and I am trying to query a database and print out the records in the row to the console window. I got it to work, but I have a feeling that there is a more concise way to do this. One thing that I am sure is wrong is that I had to convert the dataset to a datatable to be able to retrieve the values. Is that correct? Could you take a look at the code below (especially the for loop) and let me know what I can improve upon?

Jul 26, 2010My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:

Mar 21, 2011I have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...
