I know how to create and populate a datatable, which i have already done. Now, I simply want to display the datatable on a webform, but I also want to know how to paginate and sort it. Ultimately I do not want to bind this to a datagrid or gridview. I would like to learn how to programmatically do this myself.
how to display, paginate, and sort this datatable without using datagrid or gridview?
I am using vb.net code.I have grid view,the code below:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" CssClass="innerGridTable" DataKeyNames="OrgID" DataSourceID="OrgGridViewDataSource">
<PagerSettings NextPageImageUrl="~/images/arrow-right-active.gif" PreviousPageImageUrl="~/images/arrow-left-active.gif" />[code]....
I have gridview pagination, now I want to add images for previous and next button in pagination. How I can do it in the gridview.
When I attempt to go to page 2 or any other subsequent page of the data grid, it does nothing but refresh the page.
Markup:
<!--Main DataGrid-->
<asp:DataGrid
ID="dgTasks"
[Code]....
Now, I'm not even close to sure why the pagination is not working. I have AllowPaging equal to true, I'm not re-binding the data on PostBack
I am using VB.net for coding.
I am having GridView Control in my application.[code]...
I am trying to implement pagination in my gridview control. Here is the code for databind and pageindexchanged
Private Sub BindGrid()
Dim dataTable as DataTable = CType(Session.Item(APPLICATION_DATA), DataTable)
Grid.DataSource = dataTable.DefaultView
[Code].....
I am trying to get some data in DataGrid from XML files. I am reading that XML data and putting that data in DataView and giving that DataView as DataSource to DataGrid.As i have a schema for my XML, i dont even give HeaderName as system automatically takes HeaderText as whatever is in XML Tags. Now my problem is Pagination alignment, i have pagination on my DataGrid but even setting
<PagerStyle HorizontalAlign="Right" Mode="NumericPages"/>
doesn't bring pagination to extreme right of datagrid, rather it brings pagination on right of first column of datagrid(my datagrid has 9 columns) see attached pic
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Bind data to Grid
BindGrid()

I Have a web form in a asp.net web form 3.5. The listview has a checkbox on the item template, I am trying to retain the state of the checkboxes through pagination . Once I can page through records and preserver this state I need to send this to a print page which takes those ids...I have this working, but it will print only the records on each pagination. [URL]
how can this be done, the code below is not working.
Protected Sub ListView1_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewCommandEventArgs) Handles ListView1.ItemCommand
Dim myButtonPrint1 As Button = CType(ListView1.FindControl("printButton1"), Button)
If e.CommandSource Is myButtonPrint1 Then

I found that when group by multiple values does not work well with VB.NET, but it works well with C# ,here are my code, is there something wrong with my VB.NET Code? Here is my VB.NET code:

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

View 3 RepliesI created a windows form application using Visual Basic Express Edition 2008 but I did not know I could not use it on the web, which is what I wanted but being new to VB I just got a lot of headaches trying to figure this out. It works fine as a windows app but now just recently I installed Visual Web Developer 2005 to so I could create a web application from the windows app.
It is a simple windows application of a datagrid but now I want to run the same design application I made in Visual Basic to Visual Web Developer Express 2005. Is this possible? And, what do I need to do? I have all of the associated files in my project folder in Visual Basic Express folder.
how does look-up work in Visual Basic, I have done research on this but it does not explain. I have a Form1 called( Booking form) with 2 ComboBox's and 1 TextBox. each called (Destination_FromComboBox) and (Destination_ToComboBox) and (FareTextBox)and another form2 called (Fares Form) with 3 TextBox's each called TextBox1 (FromTextBox), TextBox2 (ToTextBox2), TextBox3(FareTextBox).So when I select (Booking Form) and Insert or select a Destination from (Destination_FromComboBox) and Insert or select a Destination To (Destination_ToComboBox) I want to read from (Fare Form/Fare Table) and give me the fare in FareTextBox on the Booking Form. Also on the booking I have 3 Radio Buttons
(RadioButton1 = 4 Seater Car, Normal Fare)
(RadioButton2 = 6 Seater Car, Time & HalfFare)
(RadioButton3 = 8 Seater Car, Double Fare)
But there is also a time Issue as well:
If the time is Between 05:00 & 23:59 then normal time should be used
If the time is Between 00:00 & 02:00 then time & half should be used
If the time is Between 02:00 & 05:00 then Double time should be used
I have watched loads of video's and looked through forums and other codes for the combination of the above, without success?
I have this great way to use VB6 I treated my project like a .exe file.Say I want to work on c:work directory.I just save as the .vbp file to c:work directory
All the other files (.frm,.bas,.cls) files are in a special directory called library ALL of my .vbp files, in c:work1, c:work2, c:work3 refer to that one same directory.How can I do that in vb.net?
Why this is important? Bugs always happen all the time. If I just run .exe file, when bug happen, I cannot do a thing. However, if I run the project file and run the program in debug mode, when bug happen I can figure out what happen.
I am a CS grad, but haven't had much to do with programming since my school days as I went the BA route.Anyways, there are a few things that I do manually on the computer and thought that I could probably save time by creating an application for them.But I'm not really sure how to start.I'd like to be able to keep a history of Completed eBay listing so that I know when the price point is good and when it is too high.I noticed that eBay has an RSS feed, so I think I can do it. Just a couple of quick questions:
1 - Can I instruct VB.net to open a web browser and read an RSS feed, or would I need to manually do this myself and then run the application?
2 - What is the best way to work with RSS feeds? Should I convert the data into XML first?
I am trying to get a percentage that just does not seem to work.I am using WMI to get the Total Physical memory of my system and then the Free Physical Memory. Then get the percentage.
2147483648 - Total Memory
838028 - Free memory
According to Task Manager my physical memory is 59%. This is the code I am using but I can not get 59% or 41% that is free.
temp = FM/TM
temp = temp * 100
percent = FM * temp
I have a simple application:Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
#If DEBUG Then
lblDebug.Text = "Debug"
#Else
lblDebug.Text = "Not in debug"
#End If
Now when I run it in VS, it prints "debug" like it should, but if i run the .exe, it still prints "debug". What do i have to do to get this to work right?
I'm working with VB.net.I'm having problems while I connect my application to my database today so I wanted to add an error handling to close the form.The problem is that when I put Me.close in a form, this form still open. I used the Form.Closing event handler to verify that it was called, and then ran my application in step by step which showed that the event handler was called, but the application continues and the errors appears to the user.how to close a form properly without closing the application?

I recently moved over to a Windows 7 computer and I can't get databases to work with VB.net.Before I moved I used to do an Access database and connect it to VB through the ODBC thing. However, I don't have Access on this computer (open office) so I'm not sure how to create a database and connect it.I have tried to use the SQL Compact Edition that comes with Visual Studio but I not sure how to get it to work. Also would something like mySQL work with VB? I have looked at the mySQL workbench and like it, what else would I need to download to be able to use the databases created with it in Visual Studio?

View 1 RepliesA VB 2008 program that I am developing suddenly has a problem when trying to debug with breakpoints. I set a breakpoint, but the program does not stop there. A small yellow icon appears by the breakpoint bullet and says (when moving the cursor to it) "The breakpoint will not currently be hit. No symbols have been loaded for this document". Other applications debug ok with Visual Studio, so I suspect there is some setting for this one application that has gotten messed up.
