Sep 21, 2012
I need to do calculation of different no as shown in fig..right now i am doing addition in the normal way...adding all the values of the textboxes and thenn showig the result in the last textbox..what i want is whenever i change any value in the any textboxes it should automatically reflect the changes in the final calculation(final textbox) without using calculate button.
I have a web page in asp.net+vb code+sql database. in an table named course_intake i want to count i tried some and it works correct but i am not able to add more clouse to it
1. if date1 (field) not equal to date2 (field) then att pd as 1 else 2
2. (OY is a field) if OY Ends is lesser than Jun then Deg Dt as 1 Jul+ OY end year (example if OY is 5 Jun 2012 then deg dt will be 1 Jul 12 else 1 Dec 12)
3. Count from COURSE_INTAKE where OY LIKE 'YO-' WHERE ENTRY_COURSE= ENTRY_COURSE
4. Count from COURSE_INTAKE where OY LIKE 'TAKEN YO-' WHERE ENTRY_COURSE= ENTRY_COURSE
5. Count from COURSE_INTAKE where OY LIKE 'DONE' WHERE ENTRY_COURSE= ENTRY_COURSE
My code is as under
select ENTRY_course,COUNT(*) as Str,convert (varchar, DTsen,6) as [DTSEN],convert (varchar, DTCOM,6) as [DTCOM], dbo.getBTechBECount(ENTRY_course) as 'BTECH',batch,dbo.getMedCount(ENTRY_course) as 'MED',convert (varchar, DTCOM+396,6) as [AVL for OY], str-btech AS [STR AVL] FROM COURSE_INTAKE group by ENTRY_course,DTCOM,dtsen,batch, str-btech ORDER BY dtcom

This refrence number should be unique for every user who fills the feedback form.
I'm here again to share a problem that I'm fighting against for days. I'm developing an eCommerce Cart.
Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.
When the customer clicks over the Button, it fires a function that gets the content of the TextBox and do an update on my Database.
It works perfetly when it is done with the mouse click. But I need to fires the update function WHITHOUT the manually click event. When the customer just put the mouse out of the TextBox (onblur event), I want to fires that function.
I am in the process of building a calorie calculator. I have a calculation ready to test but I am having trouble getting it to print as onto a blank label. Here is what I have so far. I just need to figure out how to print "maintainanswer" back to the user.
If dt1.Tables("PresentTotal").Rows(0).Item("C") Is System.DBNull.Value <> True Then ctxt.Text = dt1.Tables("PresentTotal").Rows(0).Item("C") Else ctxt.Text = "" End If
The script works fine for those peoples number is in that table but when the number of that person is not there in tahat table then it gives error...
I will enter the amount in "Amount" column and "Out Of 10 Percent", i will display the 10 Percent of the amount
Say Amount Out Of 10 Percent
1000 100
100 10.
I can do the calculation in C# and i can able to export the content to excel as above.
My need is in the exported excel, if change the amount means i should able to get the corresponding amount in the next column.
(i.e) in the exported excel, if i edit the "Amount" ->1000 to 500 means the next column "Out Of 10 Percent" should change as 100 -> 50. I mean it should be auto calculated in the exported excel.
I inserted a record in my database and if it is successful, then, it will automatically redirected on a certain page. However, when I click on the BACK button of the browser, it will bring back of course the previous page and at the same time, the data that I encoded still appear. How am be able my page that if in case my users click on the Back button of the browser it will redirect on a certain page or if not, the entries will not appear.
When using a simple gridview targeting .net 4.0 if i click the edit button twice it converts to BoundFields to textboxes, but in previous version of .net (3.5 and 2.0) nothing happens (eventhough msdn says it suppose to happen). Have anyone seen this issue?
Code: <asp:GridView ID="GridView1" AutoGenerateColumns="False" DataKeyNames="Id" runat="server" onrowediting="GridView1_RowEditing"> <Columns> <asp:BoundField DataField="Id" HeaderText="ID" Visible="False" /> <asp:BoundField DataField="FirstName" HeaderText="First Name" /> <asp:BoundField DataField="LastName" HeaderText="Last Name" /> <asp:TemplateField> <ItemTemplate> <asp:ImageButton ID="imageButton" AlternateText="Edit" CausesValidation="false" CommandName="Edit" runat="server" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> public partial class _Default : System.Web.UI.Page { public class Person { public string FirstName { get; set; } public string LastName { get; set; }
I have a gridview which contains asp.net textboxes. The user uses a barcode scanner which scans barcodes into the textboxes.
What I would like is to move to the next textbox after an item has been scanned in i.e. automatic tabbing to the next textbox.
Does anyone have any advise how I can do this?
What I have noticed is that when the user scans an item, the page does a full page postback even though the grid is in an update panel. And after the postback, the focus on the textbox just scanned in has been lost.
I want to automatically select the first row of Gridview after an autopostback. Here is the scenario. I have a dropdownlist that populates Gridview. On Gridview I have the option to select a record to view more information. However, after the user selects an option from the dropdownlist I want the first record in Gridview to be selected and shown in Detailsview.
I have a need for a GridView (that is initially hidden) to skip the binding to the associated SqlDataSource until the user requests a certain condition. At that point, I want to modify the SelectCommand and bind the Gridview.
I am unable to find an attribute that essentially says "don't bind this". What am I missing?
In a formview I need to present a new value calucalted by dividing one field value by another. I need to present the result to one decimal place. The code I am using is the following, however it presents the resulting value rounded up or down to the nearest whole value:
I did try and insert refernces to {0:N1} but this just threw asp.net errors. Any advise on how I can guarantee that the value calculated is presented to one decimal place?
