Over Datagrid Erasing Entries And General Datagrid Access

May 9, 2009

I have a datagrid which I am using LINQ to fill, I then add some custom columns and fill them in programmatically - if the users clicks on the column header to re-sort, all the data in the added columns disappears. I am obviously missing something very basic here but can't seem to see the forest for the trees. I also have a couple of other questions about how I am doing things:

Datagrid Control - Fill And Use Each Datagrid Indepentent From Each Other?

Jul 22, 2009

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code

Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.

Dynamic DataGrid - Dynamically "transform" DataGrid To Display The Selected Search Template

May 23, 2011

I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.

The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).

To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.

C# - Differences Between .NET 4 WPF Datagrid And WPF Toolkit Datagrid

Dec 28, 2010

what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.

I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.

Determine When App Has Had Any Activity?

Nov 11, 2011

Does anyone know of a way to detect recent activity in a VB.net windows forms application?

We have a retail store where users share floor computers, the application will be on each machine and require a log in before use. I am trying to find a way to automatically close the application if it has been idle for lets say 10 minutes.

I guess I could do something similar with the current windows log on session - set a gp that logs the user out after 10 minutes of inactivity - but if there is an easy, non memory intensive way to do it in vb.net i would rather use that method

How To Determine If DateTime Is Not Set

Jan 11, 2010

In VB6 if I wanted to see if a datetime field wasn't set, I could do something like if myDate = 0 then. I tried that with VB.NET and it can't compare to an integer. How do we do this now? I found the Ticks property, so if myDate.Ticks = 0 does seem to work, but I'm not sure if that's the "right" way to do it. None of the other things I've tried have been successful.

Dim dt As New DateTime
If dt.Ticks = 0 Then MsgBox("dt.Ticks = 0") 'this fires
If IsDBNull(dt) Then MsgBox("IsDBNull(dt)") 'doesn't fire, so no good
If Not IsDate(dt) Then MsgBox("Not IsDate(dt)") 'doesn't fire, so no good
'If dt Is Nothing Then MsgBox("dt is nothing") 'not legal syntax
