Oct 6, 2011Im working on an Asp.net / VB.net website and coming from a C# / WPF background things are still a little new to me. I have declared a DataTable like so: Public notificationList As DataTable And I have then used the Page_Load event handler to populate it and bind it to a control on my page, which all works fine
[Code]....
However in another method i need to be able to access this DataTable, yet whenever I do it always appears as nothing. Do I need to be storing this value elsewhere like in the session etc?

Storing String Item In A Date / Time DataColumn Of A DataTable
May 27, 2009I have a datatable which loads data from an Excel Spreadsheet. One of the columns in the Excel SpreadSheet was of type "Date/Time" in which date values are stored. Now I appended the datatable with three new rows and I wanted to store string values in these rows using the code below. However due to the fact that one of the columns are date/time type, an error is generated as date/time column does not accept string value. I have two questions
a. Is it possible to store string value in date/time DataColumn?
b. Is there a remedy to this situation? [code]
Best Method For Storing Values?
Feb 6, 2010Basically, I want to have a database that's lightweight and I won't need to install amillion other things on my clients computers for them to access this.I just need a simple method of reading and writing values so that they're not hardcoded into the program. I could do MySQL (which is what I'm very familiar with), but it doesn't need to be making calls remotely.

View 6 Replies[2005] Color Dialog -- Show Current Color?
Jan 15, 2009I know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
BUT, it doesn't show the current color.
They all have 0 0 0 rgb.

Asp.net - Cannot Add DataTable Values To GridView
Jan 10, 2012Here is my code
Dim dt As DataTable = New DataTable("Intervenant")
For Each column As DataControlField In grdvIntervenants.Columns
dt.Columns.Add(New DataColumn(column.HeaderText))
Next
[code]....
I am developing in ASP.NET using VB.NET as background code. I am on vs2008 with windows 7 enterprise edition.I have just restarted doing VB.Net and my first time using a gridview without a DataBase, so maybe I am missing something. Basically, I am trying to add a DataRow (dr) to a DataTable (dt) and then put said DataTable into a Gridview (grdvIntervenants).My first step is to take the gridview and put all its data into a DataTable. Then i create a DataRow(dr) that I populate with variables and I add said DataRow to the DataTable. After that, I put the DataTable as the DataSource and bind the GridView.
The problem is that my GridView shows the rows but they are empty.While debugging, I found out that this error was beside all the DataRow.Item:"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user" Seraching for it on the net.I did not totally understand the error, so i tried many different ways of adding the data into the DataRow but to no avail. I also tried different way of adding the column thinking the index problem might be coming from there, but again, the problem persisted. Now, something I found weird was that the Item property of my DataRow gives the quoted error, but I see the values into the ItemArray of the DataRow.I also found out that the same error appears beside the columns property into the dataTable.When I try to access the data from the DataSource in my rowDatabound method using the DataBinder, it gives me null results...
