How are you accepting data in masked text box? You can convert the input into your format.
For example you can say string.Format("{0:dd\MM\yyyy}",DateTime.Today.Date);
If this does not make any sense, you will have to send me some code of yours

Hi,

Please clarify what a, b, and c are. Are they c1, c2, and c3, respectively?

Hi Prashanth,
You can do the following: (case: if using data Binding)
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if ((bool)row.Cells["select"].Value.Equals(true))
{
//Do Something
}
}
In the above case the DataGrid is bound to the following table:
private DataTable Table()
{
DataTable table = new DataTable();
DataColumn col1 = new DataColumn("select",Type.GetType("System.Boolean"));
DataColumn col2 = new DataColumn("Name", Type.GetType("System.String"));
table.Columns.Add(col1);
table.Columns.Add(col2);
DataRow r1 = table.NewRow();
r1["select"] = true;
r1["Name"] = "Something";
DataRow r2 = table.NewRow();
r2["select"] = false;
r2["Name"] = "nothing";
table.Rows.Add(r1);
table.Rows.Add(r2);
return table;
}
Hope that helps.
Cheers

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
foreach (DataGridViewColumn column in dataGridView1.Columns)
{
if (column.CellType == typeof(DataGridViewCheckBoxCell))
{
//Do Something
MessageBox.Show((string)dataGridView1.Rows[e.RowIndex].Cells[1].Value);
}
}
}
This one will do the trick

Thanks again Mr.RepliCrux
but for the last statement
e.rowindex.cells[1].value
its giving object reference is not set to instatnce of object exception.
FYI i am using VB.Net does it makes any change/diff here?

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
For Each column As DataGridViewColumn In DataGridView1.Columns
If column.CellType Is GetType(DataGridViewCheckBoxCell) Then
MessageBox.Show(CType(DataGridView1.Rows(e.RowIndex).Cells(1).Value, String))
End If
Next
End Sub
This is how Vb.net code looks, The error you are getting might be because:
1. Your parser is going in that code before your datagrid is initialised.
2. I have said Cells(1) because there is some value in my Cell(1) in that row position. If there
is no Cell(1) in your datagrid you will get that exception

thnx in advance

Hi Prashanth,
The code I gave you was for your understanding how to catch the event when you click on the checkbox cell.
For Each column As DataGridViewColumn In DataGridView1.Columns
If column.CellType Is GetType(DataGridViewCheckBoxCell) Then
Dim chkCell As DataGridViewCheckBoxCell = CType(DataGridView1.Rows(e.RowIndex).Cells(0), DataGridViewCheckBoxCell)
If CType(chkCell.EditingCellFormattedValue, Boolean) = True Then
MessageBox.Show("Yes")
Else
MessageBox.Show("No")
End If
End If
Next
This works for me, cheers

Online articles generally simplify the use of an ADO connection to populate single comboboxes. I am looking for something where I can see the implementation of multiple tables (in the same database) being bound to multiple objects on a windows form.
Also, if you have multiple tables that you are retrieving/storing data from/to is it better to have each combobox loaded with data in its own function/sub or is it better to do it all in one function/sub?
Thanks,
Dan

Multiple tables in a combobox can be done through queries or stored procedures...

i am using dotnet 2003.i want to move records using firstbutton,previous button,next button,last button in vb.net windows application(not web application).

Store the record number you use to read a record, and change it ( and read the right record ) when you press a button.

You can use custom paging, just like in web application create the stored procedure which takes current page and number of recored to be displayed. On each button click bind the control with the new data.

WHY?? What on earth does a printer driver need to know about the processes running on a system?
A printer driver has but a single mission in life. Convert drawing commands from GDI/GDI+ to a language used by a printer to describe the same image on a page and communicate status information from the printer back to the spooler. That's it. Nothing else.
Are you installing this "driver" through "Add Printer..." or is this an .EXE your writing? If it's an .EXE, then it's not a printer driver you're writing.

hi all,
i want to validate text box of my windows form to a email format
i mean i want to validate my windows text box to standard email format
i didn't found the regular expression validator in windows vb.net
i came to know that i need to use ^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$
but where do i need to use( to which property of the text box)
please suggest me clearly
thnx in advance
prashanth

There is no property of the textbox that uses this. You have to handle the Validating event of the TextBox and run a RegEx match of the contents of the TextBox against the RegEx expression you have. YOU have to provide the validation code. It doesn't come standard in the TextBox.
