DataGrid Not Displaying Data From Source

Jan 12, 2011

Take text data from a small file and display it in a form using a DataGrid.

I am trying to make the program so it will allow the user to choose which file to open (this part already works). I have stepped through the code and found that the rows are being added to the table, but when the action runs to completion my form has no data on it. Here is my code (forgive any code shortcomings as I have exactly three days as a VB.NET programmer).

IDE :: Data Source Disappeared - Recreate My Data Source From The Entry That Is In App?

Feb 10, 2012

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

DB/Reporting :: IP Address Not Displaying Properly In DataGrid?

Apr 9, 2008

I have populated a dataset with the contents of a csv file. Here is a sample of the imported data:

Protocol,Process ID,Process Name,Local Address,Local Port,Remote Address,Remote Port,Status
TCP,4,SYSTEM,134.190.220.54,4505,134.190.184.193,139,ESTABLISHED

TCP,4,SYSTEM,134.190.220.54,3816,134.190.176.154,445,ESTABLISHED

Here is the code that I used to import and display the data:

Code:
Dim sConnectionString2 As String
sConnectionString2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& CasePath & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"""

[code]....

The problem is, all of the data gets displayed correctly except for the ip address. It gets truncated to "134.1892". How can I change the formatting for the "Local Address" and "Remote Address" columns.

Searching And Displaying Specific Records In A DataGrid

Apr 6, 2009

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

VS 2008 : Data Bound List Box, Displaying Data Into Textbox?

Jan 3, 2011

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.

So this is what I got.

Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"

[code]....

It only adds the first rows details to the text box when I click the second record the first rows details are still there.

If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)

If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB

How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done

Apr 23, 2010

how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.

I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:

Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"

[Code]....

The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.

The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

Multiple Combo Boxes Showing Data From The Same Data Source?

May 10, 2010

I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.

A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2

ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

Access Other Data Fields From Combo Box Data Source?

Nov 4, 2009

I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.
