View 19 RepliesI need to loop through all my db records, append some text a specific column (for all records), and save back to the db.
View 3 RepliesI have an issue with a Loop that doesn't actually loop. I've posted a simplified version of my code below. Basically, using the NPOI excel library, I have an excel file with data on the first and second sheet, so I need to do a loop to get through both sheets. Below is what I have done so far, however this only works through the first sheet and then exits. It fails to increment the variable w. As you can see, there are other loops implemented in this code which function fine so I don't get it.It's been a very long day and perhaps I'm missing something very simple. I could have it placed wrong or something. If anyone else can spot what I might be doing wrong I'd be very grateful :)

I need to loop through all the controls in my asp.net webpage and do something to the control. In one instance I'm making a giant string out of the page and emailing it to myself, and in another case I'm saving everything to a cookie. The problem is masterpages and items with collections of controls inside them. I want to be able to pass in a Page to the method, then have that method be generic enough to loop through all controls in the inner-most content page and work with them. I've tried doing this with recursion, but my recursion is incomplete. I want to pass a Page object into a method, and have that method loop through all controls in the innermost content page. How can I achieve this?
private static String controlToString(Control control)
{
StringBuilder result = new StringBuilder();
String controlID = String.Empty;
Type type = null;
foreach (Control c in control.Controls)
{
try
{
controlID = c.ID.ToString();
if (c is IEditableTextControl)
{
result.Append(controlID + ": " + ((IEditableTextControl)c).Text);
result.Append("<br />");
}
else if (c is ICheckBoxControl)
{
result.Append(controlID + ": " + ((ICheckBoxControl)c).Checked);
result.Append("<br />");
}
else if (c is ListControl)
{
result.Append(controlID + ": " + ((ListControl)c).SelectedValue);
result.Append("<br />");
}
else if (c.HasControls())
{
result.Append(controlToString(c));
}
//result.Append("<br />");
}
catch (Exception e)
{
}
}
return result.ToString();
}
Without Try/catch
Object reference not set to an instance of an object.

Ok heres the scenario: I have a table with many rows in it. Each row has a checkbox in one cell, and a span in another cell. What I want to do in my jquery is to go through the table and find each row where the checkbox is checked, and then store the value of the span in an array. I thought you might be able to do it as a selector rather than using a loop. I tried this but it didn't work
$('.cbox').is(':checked').parent().parent().children('.id-text').val();
$('res-table').find('tr')
It doesn't look very much like it would work though, and funnily enough it didn't So can I do this without using a loop?
i'd like to be able to check to see if an item with the same id has already been placed in the database, if so to then update the quantity for that item, however due to the fact I have this in a foreach loop it will update the quantity for each item.
When I placed the Command outside of the loop I am unable to use 'ItemID' as it's not in context, is there anyway I can get around this?
foreach (UserItem ItemID in (List<UserItem>)Session["UserSession"])
{
ConclusionPage.InsertCommand = "IF EXISTS (SELECT ItemID FROM tblUserItems WHERE UserID='@CurrentUser' AND ItemID='@ItemID') UPDATE tblUserItems SET Quantity = Quantity+1 WHERE (UserID = '@CurrentUser') AND (ItemID = '@ItemID')";
ConclusionPage.Insert();
}
How do I do this in a loop.

I have a datatable with 1 record only, can I reference the data in the row without a for loop? I can get to the data by using the following code, but it would be nice if I didn't have to use the For loop.
foreach (DataRow row in dataTable.Rows)
{
string name = row["Name"].ToString();
string id = row["ID"].ToString();
}
I have only one row therefore may i get its records without for loop or foreach loop
I am using this

now using the view i want to loop through ViewData["JobMeta"]
<% foreach (var JobsMeta in ViewData["JobMeta"]))
