Repeating A Code In Common In ItemTemplate And EditItemTemplate?
Jan 26, 2011
I'm a newbie in asp.net. When using FormView, there is a big amount of code in ItemTemplate, EditItemTemplate and InsertItemTemplate which is almost identical.
[Code]...
ListView allows the use of LayoutTemplate - but I didn't see any examples that insert this kind of code in LayoutTemplate. And inserting this code in LayoutTemplate would result in an error.DetailView allows to produce code automatically but I'd like to use a specific design (for ex. using "fieldset" that encompasses some fields).

I am coding a Student Management System using VB.NET and Access DOn the Form for Teacher Bio-Data, I want to use a table in which I can place Teacher Qualifications in a tabular format. In other words, say, the teacher had Primary, Secondary and Tertiary education. I want to put a header as Qualifications, Year and Grades. Is there any such tool in Visual Studio that I can use?

Wondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

I've inherited a project in VB6.NET 2008. There is a Panel control where graphs are drawn along with titles, axes, legends etc. What is drawn on the panel is also printed WYSIWYG (on a print command, of course) The problem I have is that the code for printing is entirely separate to the code for drawing. I want to merge the two so that common code is used. I'd like to work in the same units for both, which means setting either the pixels per inch for the Graphics object for the printing (so I can work in pixels) or doing the equivalent of the opposite so I can work in inches (printed inches, not screen inches).

I am trying to minimize my code writing. I have DBLayer base class that selects, inserts, updates and deletes records from database. I need only fieldlist and table name from each derived classes to perform the actions. I have defined static tablename, fieldnames in derived class. Currently I am defining next static functions in derived class for GeneralSelect [which selects all records], GeneralInsert[Which inserts a records], GeneralUpdate[Which updates records as per given id] and GeneralDelete[Which deletes a record of the given id]. The parameter and all functioning are same just the differece is the table name and fieldnames.
One DBLayer Class that performs database actions
Class DBLayer
Public shared function Query(byval SQL as string) as dataTable

I'm new to the .NET platform (old-time ASPer) and for a project have a simple pair of .aspx scripts that take some querystring data and process it. They both make use of the same Subs, Functions in them, so naturally I'd like to move the code to a common resource.vb file. Having done some reading, it looks like my options are a Code-Behind type setup, and placing the Subs, Functions in a .vb file and placing that file in App_Code.So, the Code-Behind model doesn't seem to make sense here, as the functions are shared by both files. Placing the Subs and Functions in /App_Code/resources.vb and I am getting the following error when trying to call any of the routines:

I have a bit of code where you can add a new field using an add button, which enable the asp:EditItemTemplate, but the thing is that this adds the field at the bottom of the list, making the user have to scroll down if there is enough items already in the ListView. How can I make the new item appear on top of the list?
ASP.NET CODE
<asp:ListView ID="[...]" runat="server" DataSource=<% [...] %> >
<LayoutTemplate>
[...]
</LayoutTemplate>
<ItemTemplate>

I have a Entity Data Model which abstracts an underlying MSSQL database. I have an EntityDataSource which is wired up to a GridView. The GridView has a number of columns - most are BoundFields, but one is an EditItemTemplate. Inside of this template I've placed the following[code]...
The code executes okay and I can click edit and change the selected dropdownlist, but when I click the Update button in the GridView it doesn't update the value in the database with the datavaluefield value from the edititemtemplate. How can I get it to save the selected value from the edititemtemplate to the database?

In my application, I have been getting this error each time the treeView loads it's items. This error makes my application slow on load and takes at least two minutes to load.The error is: System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TreeViewItem'
My xaml code for the treeview is: (I'm using VB.net on my ViewModel)
<TreeView ScrollViewer.VerticalScrollBarVisibility="Hidden"
ItemContainerStyle="{DynamicResource tviStyle}"
Background="#FFF0F0F0" BorderBrush="#FFE5E2DB"
[code]....
The binding of the ItemsSource is an ObservableCollection(Of TreeViewItem) thats is filled from a database.

I have the following code. It works as is, but... I am not always going to have an even number of items in the RSS feed So, at the end of the table, I might have only one table cell on the last row. So, is there a way to count the number of ItemTemplates and AlternatingItemTemplate, so if it is an odd number I would be able to add another cell <td> </td></tr> and close the table row?

I have a gridview where each columns have two template fields. One is ItemTemplate and another is EditItemTemplate. Now in EditItemTemplate it will show some textboxes where i can perform necessary editing. I can easily fetch data from each cell by using the following code-
[code]...
But how can i fetch data when the grid view is not in editing mode that is in ItemTemplate. I have tried the following-
[code]...
But its getting the exception object reference is not set to an instance of object. This is probably happening because the above code should be used in a method like RowDataBound when a row is instantiated. But I have to fetch data from some other method.Again for clarification I want to fetch data when the gridview columns are in ItemTemplate Mode.

I use Visual Web Developer 2008 Express.I have Label1 in a DataList ItemTemplate. I wish to use a button to get the text from that label and add it to text in TextBox1 which is elsewhere on the page.
I know how to do this from a standard label on a ASP.NET web page but cannot work out how to get the text from a label inside a DataList ItemTemplate.
This is what I thought I should do Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click
TextBox1.Text = TextBox1.Text & " " & DataList1.ItemTemplates.ItemTemplate.Label2.Text
End Sub
I thought that because DataList1.ItemTemplates.ItemTemplate.Label2 - System.Web.UI.WebControls.Label is what is written in the properties window header when I select the label in the DataList template.
When I try that, I get a Blue Squiggle under "DataList1.ItemTemplates" and if I hover over the squiggle the error box comes up saying " 'ItemTemplates' is not a member of 'System.Web.UI.WeControls.DataList'

I have a gridview as shown below. When the EmpType is contract the EmpID must be masked as "XXX"; for regular employees, actual EmpID should be shown. Also, when it is masked, I need to add a button control in the EmpID column.I need to do it using mark-up; not using code behind. How can we write the conditional logic for Gridview's ItemTemplate for this logic?Note: .Net 4.0
<asp:GridView ID="Gridview1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField HeaderText="AssociateID" DataField="AssociateID" />

Okay, so I wrote a few custom ItemTemplates for VS2010 that implement IWizard in VB.NET (4.0). Straight forward enough. They work during my testing, but when someone else deploys and attempts to use any of them, Visual Studio throws an incredibly generic Exception has been thrown by a target of invocation error.
Stranger still, after they open up the project properties and try again... they work. Without changing anything. Anyone have any clue what is going on? Or perhaps even just a way of getting VS to give me a more specific error? I already tried devenv.exe /log but nothing out of the ordinary was there.

How can I create alternating background colors for listview rows while only using ItemTemplate? I don't want to use AlternateTemplate because I would have to edit both of them everytime I want to change something when all I'm using it for is to create the alternating background colors. So what's a way I could do it using only the ItemTemplate?

Modifying data with the ListView's EditItemTemplate by programmatically settings its DataSource property and calling its DataBind method. I don't have option to use data source control for ListView. All ListViews are bound with data from code-behind. So, I have to handle the Edit/Update mode of ListView manually. [Code]

Before getting started, I'm new to VB and currently using Visual Basic 2010 Express. Just want to make sure I've got this in the right forum and my apologies if I'm not.[code]...
I have 16 cities (those would be my string variables, right?) that I want to appear on my 16 labels in random order without repeating when I click the button. So basically label 1 can be any of my 16 cities, label 2 then will be any of 15 left available cities, and so on and so on.

I have a datagridview that is being loaded from a dataset. This dataset is the result of a SQL Statement (which could be my problem). The MS Access Client table is the main table and contains 2 records, however, after loading the dataset, the row count is 3.
Below is the procedure where I load the dataset and then the DGV.
Public Function LoadClientDataSet()
Try
strSQL = "SELECT A.clientID, A.name, B.phone, B.zipCode, B.stateCD " & _

If say in my datatable i have one column called order number and one column called line. Whats the best way to keep repeating the order number into everyrow, whilst incrementing the line number until i add a new value in the order number column.
So it'd go like this..
Order#______Line
4568________1
4568________2
4981________1

I'm working on a Bingo game that generates a random letter and number.
Dim RandN As New Random()
Dim randnumber = RandN.Next(1, 30)
Dim RandL As New Random()
Dim randletter = RandL.Next(1, 5)
All that works, but I'd like it not to repeat a combination. Any tips on how to do that?
Also the random numbers tend to be repetitive and the random letter is never 5. I think the random number has been 30 before but I can't be sure. Is there a way to fix that or just a better way to do the random numbers?
