Datagridview Winform Tag Only Brings Back The First Row Value?

Sep 3, 2009

I'm using visual studio 2008. i have a datagridview in a winform. I've bound to it using an object

Private Sub LoadAllCampers()
Dim Os As List(Of LE.Camper) = Nothing
Dim Oc As New LE.Camper_Controller
Os = Oc.GetCamperData(0)

[Code]...

I have a tag setup on the ID property within the Camper class. when i double click on a row in teh datagridview, i do a me.dgResults.tag and it always shows the first rows ID value. If i change the ordering within the class, it will display a different value, but it's always the first value in the datagridview. I'm missing something simple to get this working.. just don't know what it is.

I have used datagridview in the form and using FillBytoolstrip option, can filter data using type.

But i have no idea as to how can i update the database to reflect the latest changes in the gridview.

following is the code I have used.

Private Sub BOM_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.PartnoTableAdapter.Fill(Me.HemDatabase1DataSet3.partno)

.net - Show A Selection Border Rather Than Back-colour In A DataGridView?

Jun 15, 2009

My DGV has row BackColors set to various colours based on business logic. When a user selects the row the colour changes to the selected row BackColor thus obscuring the pre-set colour. I would like to preserve the original colour when a row is selected and indicate selection with (perhaps) a bold border around the selected row.

EDIT :To make it clear, this is a WinForms app.

DataGridView - Update The Change Back To The Bound Table

Dec 17, 2011

I have a DataGridView bound to a data table. I have one column where I permit updates. After I fill the table (at form load), I make an update to this column Then I attempt to update the change back to the bound table. I get the error 'Update requires a valid Updatecommand when passed dataRow collection with modified rows'. I have seen some examples on-line to define, load, and update but since I have the generated datagridview with bindings, shouldn't the update method me a simple 1-liner? [Code]

DB/Reporting :: DataGridView Back To SQL Database Through Stored Procedure

Feb 18, 2009

I have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]

Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.

I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.

If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.

VS 2010 Writing A String Back To A Datagridview Cell?

Nov 8, 2010

I've made a function to convert a number and fraction string eg. "22 7/8" to decimal. I've no problem pulling the data from the current row cell to pass through the function. Checked it via a temp textbox i put on the form. What i actuall want to do is pass it back to another cell on the current row. Tried a few things but having no luck. Here's the code of what works. The name of the cell i'm trying to pass the result back to is called "BaseDec".

Custom Control And Datagridview ComboBox Cell Back Color

Jun 5, 2009

I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.

I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.

Passing Back Lisbox Values When Going Back To Previous Page?

Jul 23, 2009

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

Delay In Back To Back Messages Through Socket

May 10, 2012

We have a server application and a client application that communicates with each other using socket.

When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.

We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.

Smtp :: Sending Back To Back Emails?

Jun 17, 2011

We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

Have A Slew Of IF Statements Back To Back?

Mar 2, 2011

I am creating an application that will be faced with multiple decisions to make and I want to know if it is possible to create around 20 if statements to excute or decide between before excuting?

The application will encounter multiple websites but each website will have the same elements but not neccessary in the same order so I was going to tell the app to loop through the IF statement and if the condition is met to run that sub routine where it starts over and loops through the IF statements until next condition is met.

Is this possible in VB.NET or is 20 or so IF statements to many to use at once?[code]...

.net Xml To Dataset Back To Xml?

Jul 28, 2009

I recieve a failry complex XML from a web service (30+ tables; with nesting). I need to be able to look a this data; make mods and then pass it back (still well formed per xsd) to the web site. I am able to parse it both natively in XML and by putting it into a dataset. I am more comfortable working in a dataset so thought the best approach for me would be to take the XML to a dataset dsOrder.ReadXml(XMLreader) (also tried with inferschema switch) work with it as required; then using _newXML_str = dsOrder.GetXml

put the dataseet back into xml. This almost works, but the XML while well formed does not adhere to the schema. In particular, it appears that all the simple types for a table are put ahead of the complex types (even thoguh the schema wants some of these items intermixed), so when sent back to the web site, it complains about the order of the tags.

is there a way to get the xml from dataset command to form an xml that will ahdere to the schema? I tried using the available xsd to influence this process but it either doesn't work or I did not know how to apply it properly. If someone has a suggestion for this application I would appreciate comments and any detailed samples that come to hand. I am working in vss 2008; framework 2.0; and use vb.net.

FileDateTime To Get UTC (GMT) Back?

Apr 29, 2012

I have an app that goes out and looks at some files for the Date & Time so that I can compare later for if a newer file is in a directory.However I have seen that between some file copy's, I have files reporting back different time stamps, but in actually the files are the same, and I am assuming the time zone may be off of one of the computers that the file is copied from.How can I make this work correctly? This is what I have, but it still returns the files with the hour off between them and the UTC is changing the time, but still get the hour difference. (Obviously i'm changing the strPattern to whichever directory.I am looking at):

strStamp = FileDateTime(strPattern).ToUniversalTime

is there a different property on the file I should look for? The files belong to a software program, so they are not your typical .txt files or anything.
