Greetings,
I have a VB.NET program that I am trying to convert to C# (my office
decided that we are going to use C# from now on).
I've only been working with C# for about a month now, so this has been
quite the learning experience for me.
The following code is from my VB.NET program and it selects the Call Number
from my datagrid and then uses that information to populate another form.
I cannot seem to find the appropriate adjustment for the CurrencyManager
to reproduce the effect in C#.
Could someone please help me?
Thanks,
Kris
Private Sub btnSelect_Click (ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles btnSelect.Click
Dim cm As CurrencyManager = CType(Me.Bindin gContext
(dgdContactInfo .DataSource, dgdContactInfo. DataMember), CurrencyManager )
' Retrieve the default DataView of the DataGrid
Dim dv As DataView = CType(cm.List, DataView)
Dim dr As DataRow
dr = dv.Item(cm.Posi tion).Row
strCallNumber = dr("Call Number")
myForm.CallNumb er = strCallNumber
myForm.Show()
Me.Hide()
End Sub

Well "Me" in VB = "this" in C#, both are implied by context and so including
them is a matter of preference or clarity.
CType() in VB doesn't have an exact equivalent in C#, however, you could
have as easily used DirectCast() which is somewhat faster than CType()
anyway and that is exactly equivalent to C# casts:
Dim cm As Currency Manager =
DirectCast(Bind ingContext(dgdC ontactInfo.Data Source,dgdConta ctInfo.DataMemb er),CurrencyMan ager)
Converting this to C# you would get:
Currency Manager cm =
(CurrencyManage r)BindingContex t(dgdContactInf o.DataSource,dg dContactInfo.Da taMember)
Later on, you can substitute the indexer for the Item property:
dr = dv[cm.Position].Row;
Hope this helps.

The following was obtained with our Instant C# VB.NET to C# converter.
Our Demo Edition is available at www.instantcsharp.com and is fully supported.
//TODO: INSTANT C# TODO TASK: Insert the following converted event handlers
at the end of the 'InitializeComp onent' method for forms or into a
constructor for other classes:
btnSelect.Click += new System.EventHan dler(btnSelect_ Click);
private void btnSelect_Click (object sender, System.EventArg s e)
{
CurrencyManager cm =
(CurrencyManage r)(this.Binding Context[dgdContactInfo. DataSource,
dgdContactInfo. DataMember]);
// Retrieve the default DataView of the DataGrid
DataView dv = (DataView)(cm.L ist);
DataRow dr = null;
dr = dv[cm.Position].Row;
strCallNumber = dr["Call Number"];
myForm.CallNumb er = strCallNumber;
myForm.Show();
this.Hide();
}

I have written a custom databound grid control that we've been using
successfully for months, but one of our developers has just run into a
problem that I can't figure out.
The code for setting it up is as follows:

DataTable tableParent = dataSet.Tables.Add( "TableParent" );
tableParent.Columns.Add( "ID", typeof( Int32 ) );

I created a class derived from a DataGridTextBoxColumn.
I have it working through looking at various examples on the net.
To update the underlying DataGrid, I had to overload the Edit method which
provided the CurrencyManager and row number required for SetColumnAtRow

My question is, exactly is the CurrencyManager? I've used it, but I don't
understand it.

I have a dataset containing 2 tables. A is the master table, B is a lookup

my currencymanager is created thus:

The cbx has these settings:
