Get Text From A Label In A DataList ItemTemplate?
Apr 13, 2010
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'm trying to export the details in my datalist into a PDF file by using this third part program called Itextsharp. However, I'm encountering problems in generating the PDF as it keeps giving me the "Object reference not set to an instance of an object" error which points to my "htmlparser.Parse(sr)"
I been trying for 2 hours now to fix this problem however no progress. Does anyone here have experience in Itextsharp?
Here is the code that runs the export to PDF command
Protected Sub Button15_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.ContentType = "application/pdf"
Response.AddHeader("content-disposition", "attachment;filename=Resume.pdf")

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.
Sub f1timer2tick()
Dim g As Graphics = f1l2.CreateGraphics
Dim s As SizeF
If f1l2.Text.Length > 19 Then

basically i need to change the text of a label where the name of the label comes from the value of a variable.So, for example,
Dim x as String = "lblTarget"
Dim y as String = "Target Text"
In this case the text of "lblTarget" would need to be come "Target Text". Basically, the label that is named the value of variable x would need to take on the text of variable y.

Is there any way to detect if the text in a label is longer than the label itself (assuming autosize is set to false)? I want to trim the text in a label so the last line is a finished sentence (everything after that sentence is removed). I hope you understand what I mean.
I want to go from this:"Hello. This is a test string. Most test stri..."
to"Hello. This is a test string."
Is there any easy way to do this?

I am creating a Pizza Order program as part of my coursework college. why something isn't working.
Quote:
lblTotal.Text = Val(Form2.lblPizzaTotal.Text) + Val(Form3.lblDrinksTotal.Text)
The code above is what I am using to add the Value of Label 1 (Pizza Total) and Label 2 (Drinks Total), however it seems that in the final total it doesn't appear to add the value of Label 2.

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 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" />

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).

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?

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]
