• Windows Forms Invisible DataGridView - scroll problems

  Hi, since the DataGridView does not support BeginUpdata / EndUpdate I tried to enhance performance by making the following dataGridView1.Visible = false ; LoadTheData2TheBindingSource(); dataGridView1.Visible = true ;   I add about 4000 Rows in the function. After this the DGV Scrollbar looks as if there are only a few records more than visible. When I use a BindingNavigator i can iterate all the records, but they apear on one place in the last but one row of the grid. When (after navigating down) the DGV gets the focus an exception is raised: ************** Exception Text ************** System.ArgumentOutOfRangeException: ...Show All

• Visual Studio Any Practical Limits on Model Size?

  If models are each stored in their own XML file, what is the practical limit on the number of objects in a model   We are considering moving an existing application generator into DSL.   The models contain thousands of objects. Hi DRB, To be honest, its probably not terribly practical to code this up using the current CTP as you'd have to completely replace the serialization scheme by hand and also get into managing multiple docdata objects. This is an area we're actively investigating for a future CTP. Sorry if I gave the impression that this was a "now" thing as opposed to a "future" thing. ...Show All

• Visual Basic TextBox Property

  Hi I am very new to VB.NET programming and I hope that somebody will be able to help on what should be an easy question!! I am using Beta 2 and basically i have data-bound a text box to a decimal field in an sql database. Essentially what i am trying to do is force the user to only enter in an 99.99 format.  I know that i can validate to check the input is valid but of course it would be good if they could actually only enter in that format.  I will have the same problem when it comes to entering monetary values later. I have looked through all the properties on a textbox but can not find anything.  Can anyone point me in ...Show All
