DataGridView Getting Rid Of The 'new Row' (asterisk Row)?

Sep 16, 2010

This is my first time using DataGridView, and I've managed to solve most of my problems but one.In my datagridview table, I want the user to be able to add and remove rows as they please, they just select the row, click delete, and that row is goneMy problem is there is a row that is labeled the "new row" (i think?) that has an asterisk beside it(to the left) that will generate an error if you try to delete it.How do I remove the asterisk beside the row and make it so the row is deleteable by the user, and that it will not generate an error?Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Try
If DataGridView1.CurrentRow.IsNewRow Then
'This is not ok. I do not want to have to have this If section here.

IDE :: Assemblyversion Not Incremented While Asterisk Is Used

Jun 18, 2008

When I rebuild a VB.NET solution (class-lib, winforms) in VS.NET 2008 prof, the assembly-version isn't updated anymore.This i a project which i used to open in VS.NET 2005, but converted to VS.NET 2008 (no code changes, because is a ms.NET 2.0 project)I have the only following in my AssemblyInvo. vb <Assembly: AssemblyVersion("2.0.*")> Before it worked in VS.NET 2005 (when I reopened Vs and rebuilded, the assembly-version info did changed). But now when i reopen the VS.NET 2008 solution, change something, rebuild --> the assembly-version info did NOT change. Even closing vs.NET 2008 an reopen, change, rebuild --> still no changes in the assembly-version...Why doesn't work this anymore (It still works in a C# project) ? My custom-auto-update solution uses the internal versions of the dll's, exe,

Create Asterisk Square Using For Loops?

Oct 26, 2010

I'm having a little trouble with this assignment for my 1341 Fundamentals class...A copy of the assignment can be found here. The section I'm having trouble with right now is as follows:

Quote:

Add another TextBox and Button to your program window; label the TextBox side: and change the Text of the Button to Print hollow box. Write code to clear the ListBox and then print a hollow square box of asterisks with sides of length equal to the input number. For example, if the number entered is 10, the output should look like

VS 2008 : Creating Asterisk Square Using For Loops?

**********

[code]....

You may want to use a For loop inside a For loop. Use a string to build each line of output before you send it to the ListBox. Your program should produce correct output even if the input is 0 or 1. Be sure to catch all exceptions and handle them intelligently. After this step, your program window should look like this.

NOTE: I had some trouble getting the desired output for the 10 and 4 user inputs to print out right... Rather than there being 2 rows next to each other, they should be spread apart by the number of asterisks on the top (and bottom...) thus creating the "asterisk square".

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.

Get Every Nth Row From DataGridView?

I have two DataGridViews, one displays months running for 25 years, the other displays years for 25 years.I need to display some of the columns from dgvMonths to dgvYears, but, as implied, I need to show the corresponding year to the right month.

For example Month 12 would be showed in Year 1, and Month 24 would be shown in Year 2 - if I display the start of year it will confuse the clients quite a bit, as they won't quite know what's going on as well as what their position will be at the end of the particular year.

I'm using the code below at the moment, but it's not right because at the end of year 1 (month 12) it shows month 13 instead of month 12.

Dim count As Integer
count = (dgvYears.Rows.Count - 1) * 12
Dim x As Integer = 0
