I want to convert Label text into Integer datatype. I tried by giving Convert.Int32(Label1.Text) and int.Parse(Label1.Text) but I couldn't do Type casting . I am getting error at runtime. I searched in web I couldn't get the solution.

I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'

I am trying to do some calculation in the page behind .cs like this:

i am using visual studio 2008 vb. i have a dropdownlist in my detailsview populated with product id. when i select an id, the product name will appear on a label. however, when i change the product id in the dropdownlist, an error occur "Conversion from string "ProductName" to type 'Integer' is not valid." Here's the code file.
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim lbl As Label = DetailsViewOrderDetails.FindControl("Label4")
Dim ddl As DropDownList = DetailsViewOrderDetails.FindControl("DropDownList1")
lbl.Text = ddl.SelectedValue("ProductName").ToString()
End Sub
Anyone have this problem. When you write a ex. label name or label text in the properties window, it look like its updating the text before you actually are finish. This make you type over what you allready wrote. Its not a big problem,
View 2 RepliesI am having an issue with C# and separating current day, and month into integers. I tried the code in MSDN but it doesn't work.

Labels display nothing, but code shows no errors, and you can see I tried 2 different ways of doing it.
Currently using VS2008, VB.NET, SQL. I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.
I am grabbing the field from the FormView as such:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.
What I have tried so far:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
Dim AvgTicket1 As Integer
AvgTicket1 = Double.Parse(AvgTicket.Text)
Do something with AvgTicket1
I have also attempted to Round the Value, then convert it and call it - no luck.
Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.
What are some methods I can successfully convert this value to an integer from a label?

View 10 Repliesint val = lstvRecordsCus.SelectedItems[0].SubItems[0];
The returned value is an int in a string datatype. I need the right hand side to return the value in int instead of string.
I tried Convert.ToInt32, it didn't work.
All the values that comes from SelectedItems[0].SubItems[0] is of type int.

View 4 RepliesI have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>
Is it possible to display or hide a label based on the text rendered in it?
I have a label that will display the value of a control on the previous page. If the value rendered is "0" then I want to hide the label or hide the label and one more label associated with it. (or if the value is more than "0" make it visible.
My problem is when a label's text property has a value without space and bigger than it's width property. -Mostly when i enter a link url- The text of label exceeds the width of label!
View 9 RepliesI am trying to reconstruct a date/time period from five data elements Year, StartMonth, StartDate, EndMonth, EndDate If the event starts on June 5 and ends on June 6, 2010 - The label would read June 5 thru 6, 2010. If the event starts on June 30 and ends on July 2, 2010 - the Label would read June 30 thru July 2, 2010. and if the event starts on June 5 and ends on June 5, 2010 - The label would read June 5, 2010. I've tried a few variations without success. This one comes closest to what I'm aiming for.

I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.
View 3 RepliesI have a @message parameter in SP, user sends an Integer value in that message. For Ex: @message = 'This is, a Test message 500000 and the message ends.'Now i want to get only that 500000 value from this @message param. There is no delimiters for identifying the integer value and in that param contains only one integer value
create procedure st_test (@message varchar (4000), @result int output)

I have a form where users enter information in a multi-line text box. This could be anything, such as bullets, carriage return line feeds, etc. Think of anything that you might copy and paste into a multi-line text box from Word Pad, or Word. I then store this information into a SQL Server NText field.When I retreive this information, I need to display it as the user entered it into the text box field into a Literal or Label control (or something else if there is a better alternative) to display it. Problem is that when I display this text into the Text
property of a Literal control everything is jumbled and all characters (bullets) are lost, no carriage returns, etc. One big mush of stuff. If I display this information in the Text property of Label control, I get the bullet characters, but no carriage returns
If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?
Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?
