State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?
Mar 23, 2011I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

Forms Data Controls :: Converting Dataview Column Info Into Integer?
Jan 15, 2010I have the following code reading in my xml file and sorting it by ID:
Dim ds As New DataSet
ds.ReadXml(Server.MapPath("/posts.xml"))
Dim dv As New DataView(ds.Tables(0))
dv.Sort = "id desc"
The only problem is that it isn't sorting it numerically (it's sorting it alphabetically 1, 10, 11, 2, 24, 3, 4...). It appears as though I have to convert that column into integers, but I haven't been able to figure out an efficient way to do that.
im ds As New DataSet
ds.ReadXml(Server.MapPath("/App_Data/posts.xml"))
'ds.Tables(0).Columns(0).DataType = TypeOf(Decimal)
Dim dv As New DataView(ds.Tables(0))
'dv.Sort = "date"
Converting Decimal In A Label To An Integer?
Mar 28, 2011Currently 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 2 RepliesConverting Char To Integer Representation C#?
Mar 9, 2011When I try to run the following code it always spits out the hex representation, not the integer representation. Most of the examples I found on MSDN said this should work. What am I missing?
var stringBuilder = new StringBuilder("8");
int j = 0;
foreach (char item in stringBuilder.ToString())
{
j = Convert.ToInt32(item); //returns 38, need return to be 56
}
edit I should have made clear that I know the difference it's returning the hex value. I'm outputting the value to a file, and in that file, it still shows the hex value, not the integer, so I don't think it has anything to do with the debugging environment. edit2 Looks like a PEBKAC problem. Looked at the code that was writing to the file, and it was using a .toString("X") method, changing it to a Hex value. The fact that it was hex in my debug environment was what confused me.

Forms Data Controls :: Format Integer Field In Gridview?
Dec 23, 2010I have a GridView that records can be added to.There are only 2 fields in the table that the records come from which are date field and an integer field.The date field is fine "as is".The problem is that you can't format the integer field.I have tried every way that I can think off.The last 2 ways that I have tried have used String.Format because I am using EVal and with Eval you can supply anoptional second parameter to specify a format for the returned string.I have tried in both html and code behind , html gives an error message but the code behind (code behindthe RowDataBound method) doesn't give an error message:In the html looks like:
<ItemTemplate>
<%# Eval(("inFrmDate").ToString(), String.Format("{G}")) %>

Inserting 'Nothing' Into Integer Field Through Xsd?
Nov 23, 2010I have an integer field in my sql database and I have an xsd set up with all the CRUD operations. I need to put the value in a variable into the this integer field. Sometimes the value is 'nothing'. I have option strict on so there's no conversions going on by itself. If I hard code 'nothing' into the insert query, it works fine. Here's what happens otherwise:
1) If I put a variable into the query, when I assign 'nothing' to the variable, it becomes 0 so it puts a 0 into my database.
2) If I use an iif( ) statement, it also converts 'nothing' to 0
I don't seem to have any way to get a nothing in there if I don't specifically write 'nothing'.

Access :: Sorting A DataTable By String / Integer Field?
Feb 23, 2010i'm trying to sort a datatable using the typical select method*. The problem comes because the field is string defined but it's containing integer values.
With sql the problem will be solved just using something like:
select * from table order by to_number(field);
but of course it's not working properly with the method commented above (select method).
