I am using vb.net.I'll be using a datagridview which is bound to a datasource.Normally it'll load datas in first row(row(0)) to n th row,i want to load datas only from second row.my question is how to left the first row blank.
View 2 Repliesfollowing is the code at button event which copy data from one DGV (dgvAccesList) to another DGV (dgvProbReport) and its working properly. Its paste data to 3rd and 4th column of destination DGV.But the problem is that, if at source DGV first column and second column have data..lets say up to 2 rows..then its copied data starting from 3rd row..for the 3rd and 4th column..which is incorrect..its should be always start with first row of third and fourth column.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
For Each dgvRow As DataGridViewRow In dgvAccesList.SelectedRows
Dim dgvNewRow As New DataGridViewRow
dgvNewRow.CreateCells(Inward.dgvProbReport)

Basically I would like to have an sql statement which selects all the bookings from a table in microsoft access callled tblBookings where a certain date (selected by a datetimepicker) selected in vb.net.
The field the date is in access is bookingsdate and that is a shortdate aswell.
The problem is that even if the dates are the same the headers come up in the datagridview but no data.
This is my code:
Dim con As New OleDb.OleDbConnection
Dim OleDBCon As System.Data.OleDb.OleDbConnection
Dim ds As New DataSet

On a data grid view there is a blank row with a (*) in it that allows the user to insert a new row of data.Is there a way to put focus on that row using code even though the data grid view has many rows already loaded in it?

View 4 RepliesI'm populating the datagridview at runtime based on user input. The issue I'm having is that the the combobox is displaying blank. The item I need is in the dropdown (I've added it), but I can't get it selected by default. I've tried the display member but that's not working.

View 1 RepliesI want to add just one line in DataGridView with blank values.
View 11 RepliesI've inherited a form that has a DataGridView that is bound to a dataadapter and it is connected to a binding source. Within the DataGridView is a combo box that is bound to its own bindingsource which basically just calls a stored proc to bring back the possible values for the dropdown combo control
With a blank new row and sometimes even with an existing row, this value for the combo box can be NULL which is a legitimate value for it if no value selected. Problem is everything is so tightly bound if the user mistakinly clicks the dropdown then a value is populated and there's no way to get back to NULL
I've tried to catch the mousecelldown event and others to try to catch this before a value is selected but the Cancel=True doesn't work - I can catch the event but don't know how to return the cell to unclicked or reset it to NULL or pre selected value if NULL I know how to at a new row with the datatable and then set the combo datasource to it and I have my null blank value but with a tightly bound control how do I add this row?

How to display datagridview with default six blank rows and two columns.
View 4 RepliesIf a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.
Is it possible to tell the DataGridView to un-mark this row as being changed?
Is it possible to reset this row when focus is off the DataGridView?
We are using the following event handler to alert the user if the Invoiced On is left blank:
Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _
ByVal e As DataGridViewCellValidatingEventArgs) _

Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.

I am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.
the code bellow for preview/print .it ok but when i leave the first row ...don't care which cell is blank.The Error was appear"conversion "> =" DBNULL to string "" invalid"IF the cell at the first rows is not blank .i can print that data[code].....

I've got a small VB.net 2010 project I made at home and then brought to work on a flash drive.However, when I opened the project at work, I found that my first form (Form 1) doesn't work correctly.It shows up in the solution explorer with the module icon instead of the form icon and if I open it it's just a blank empty document.When I run the project, it works correctly and Form 1 opens and appears as it should. I can also open the Form 1 design file and all the information is there, I just can't access it when I open the entire project.

I've got a working chart (ASP.NET/VB.NET), over some selected periods of time it has no data, this is expected. When I select a period of time where there is no data I get no chart displayed, just a rectangle of the background colour of the chart.
What I want is to still display the titles, x and y axes etc when there is no data, just an empty chart.
I toyed with the idea of adding a data point outside the time scale of the chart and this worked, I then got an empty graph, but there must be a cleaner way to achieve this.
