Get The Filtered Rows Into A Dataset Or Datatable In A Datagridview Bounded To A Bindingsource?
Nov 22, 2009I have a datagridview bounded to a bindingsource (that is, in turn, bounded to a dataset that is the data origin of the project) and a bindingnavigator to a Access table, all of this done with the visual designer of Visual Basic .net 2005. I want to print in a crystal report the rows shown in the datagridview after filtered using the .filter property of the datagridview. But, to achieve this, I need to get the filtered rows in a dataset, and I havenīt got this in any way. If I pass to the crystal report the main dataset origin of the project, it will print all the rows, not only the filtered rows. I would have figured out that there would be a .getfilteredrows or something like that in the bindingsource object, but there isnīt. I managed to get this manually, through a loop, but I canīt believe it is the solution experts use.

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?
Jul 30, 2010How 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.

VS 2008 Search Of Rows In A DataGridView?
Jun 20, 2010I'm doing a simple search of rows in a DataGridView. If the search finds a record matching the search criteria that row gets selected. I just added the BindingSource.Find method
If the row I'm searching for is currently showing in the DGV's viewable area, then my code will find the record, if it's not showing, meaning you have to scroll up or down to see the record, my search does not find the record.

VS 2008 Getting Filtered Data Using With A BindingSource?
Oct 17, 2009I'm using a bindingsource to bind a dataset to a datagridview. Normally I would use a dataview to sort and filter the data, but since a bindingsource can also do this, I figured I would not need a dataview anymore. But I'm not sure how to get certain data from the filtered source. I know I can get it from the datagridview, but I'm not loading the entire dataset into the datagridview. I guess I could and then just make the columns I don't need be invisible. Or I could go ahead and use a dataview also, but that seems redundant. I was wondering if there is an equivalent to this code to get a specific item from a dataview, but pulling it from the bindingsource:
tbCode.Text = dv.Item(m_recno).Item("CodeNo")
As long as I'm not filtering the data, I can get it from the dataset, but when it's filtered, the indexes won't match.

I tried an ElseIf me.combobox1.selectedindex = 0 then me.combobox1.selectedindex = -1 too and that doesn't work either, so I'm obviously doing something wrong there.

VS 2008 : Writing Contents Of Datagridview In Formatted Colums/rows?
May 19, 2009I have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.

Save 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

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.
DataGridView - Nonvisible Rows Are Still Visible And The DataGridView Is Empty Despite Having A DataSource
Jul 30, 2009I 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".
