DB/Reporting :: Displaying DataGridView Text Column In A Mixed Bound/Unbound DataGridView?

Mar 15, 2011

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

DataGridView - Nonvisible Rows Are Still Visible And The DataGridView Is Empty Despite Having A DataSource

Jul 30, 2009

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".

How To Make A Combox In A Datagridview Change Output In Textbox In Same Datagridview

Jan 29, 2010

I am using VS2008 and I have a form which has a datagridview. This is for an invoice where I already have the user select the customer from a details view and want to have the items in the datagridview change based on what the customer selected. Then when the item is selected I want to have the price change accordingly.
So far I have the customer selction as well as the item combobox(not limited to cust items yet) appear, but I cannot figure out how to get the join of the 2 items (cust+item as the price varies from cust to cust) to change the price. Question is, is it possible to do this in the same datagridview, or should i try to just break this down some other way?

Get Datagridview Table Row When Datagridview Datasource Is DataTable?

Dec 8, 2010

My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..

I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..

When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:


Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"

Winforms DataGridView Select New Row On Sorted DataGridView?

Nov 16, 2011

Alright I have a DataGridView, where the user can click on the column headers to sort. When they add a new row while a sort is applied, the record isn't created until the moment they validate the row(which they cannot do till they exit the newRow). How can I make the row be selected once it is sorted?The DataGridView is databound.The selection mode for the grid is full row.I'm using VB.NET with SQLite database backend.I suspect I need to use the RowsAdded event, or DataBindingComplete events. The records in question do have a unique GUID attached but it is NOT visible in the DataGridView.
