I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.

I have a templated control embedding a checkbox in a GridView I have an event on the checkbox which has a loop that pulls ALL of the checked checkboxes and the associated value. I only want to pull the datavalue of the checkbox that I just checked but the properties/methods associated with that checkbox event are not giving me any sort of index or item.value from which to do this.
I am currently adding checkbox functionality to a system. I would like to check a group of users and add them into a db table. I currently have the administrator values flowing into the db table fine but it will not insert the empID into the table from the gridview. Here is my code:[Code]....
I use a gridview with products, in which one column lists the manufacturer, and the next colum lists the item number.This gridview works fine, but now I want to add a product image on the same row. Instead of using a stored image location, I simply want to make a link to the image like this:
"www.mywebsite.com/images/manufacturer/itemnumber.jpg "where the manufacturer and the itemnumber are the same as displayed in that particular row in the manufacturer and itemnumber columns. I am not versed well enough (yet???) to reuse the data from those two columns.
Using a class component, an Object data source and a formview I am successfully pulliing data from a SQL database. In some cases the rows contain one or more Null values and I would like them to be ignored completely. My simple code follows:-
Im generating reports with around 8000 to 10000 records in grid view , my page give me time out error if data exceeds and it gives time out exactly after 30 secs.i have given command time out = 0 in webconfig file , but it still gives me the error . i have been using command time out property in code behind also
I currently designed a school result portal. If the students want to view their result, they input their student school number in a text box to search out their result. But this is not secured because anybody can look up any students result if you have the number which is even written on their school uniform for identification.
I have being trying to secure this result by trying to generate or code special numbers that the students will input with their school number. The special numbers will be random numbers and may be from 10 and above, it might even contain letters. How do I code this. I believe this is the best asp.net forum. I want the students to be inputing this special unique numbers and their student numbers so that there result will be avaliable to them.
I have this simple project which needs to show location on a google map by pulling data from the DB.I am using asp.net, mysql DB, google map and i found out from some website that i needed to use ajax.
The process is like this
1. I have a event form where i have multiple fields to fill in and it includes a Location/Venue fields which i can enter a location by Name(Not the Co-ordination). I am located in Singapore. So all fields will be stored into the DB.
2. I have a webpage displaying a table of the data from the same DB, and it comes with a embedded Google Map. On the table, the value of the Location column will be Hyperlinked, and when i click it, it will act as a search query in the embedded google map and locate the address without reloading the page again(which i believe i gotta use iframe?)
I am working on an asp webform that pulls from an ODBC datasource then puts the data in an sql server. Once the data is in the sql server several queries pull data from it to provide information for a report.
This is an example of what I am talking about
private void ODBCpdEmployeeAb() { DataTable dt = new DataTable();
[Code]....
The first part gets the data from the ODBC connection and the next part stores it in an sql server table. The problem is I have these methods in the page load event of the webform so everytime it loads it just puts the exact same data in the sql server table which would then provide incorrect information on the report.
Is there a way to append the most recent data from the ODBC table to the sql server ?
I was hired to do some contract work for a short contract. I am looking at this code on this Aspx web form. What they do is load the labels for a radio button list from an ObjectDataSource object. Well this is the first time I have ever heard of an ObjectDataSource. The problem is that I don't even know where this object is pulling data from. With a SqlDataSource object, I can easily view the flyout menu to see the sql query where the data is being pulled from. Anyway, I need some figuring out where objectDataSourcePlanType lives and where it is pulling data from. I know I can't list the entire project, but I am sure someone who is familiar with ObjectDataSource

I have written a web scraping program to go to a list of pages and write all the html to a file. The problem is that when I pull a block of text some of the characters get written as '�'. How do I pull those characters into my text file? Here is my code:
// our third request is for the actual webpage after the login. HttpWebRequest request = (HttpWebRequest)WebRequest.Create(baseUri); request.Method = "GET"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"; //get the response object, so that we may get the session cookie. HttpWebResponse response = (HttpWebResponse)request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); // and read the response string page = reader.ReadToEnd(); StreamWriter SW; string filename = string.Format("{0}.txt", id.ToString()); SW = File.AppendText("C:\Share\" + filename); SW.Write(page); reader.Close(); response.Close();
I'm getting ready to start a C# web application project and just wanted some opinions regarding pulling data from a database. As far as I can tell, I can either use C# code to access the database from the code behind (i.e. LINQ) of my web app or I can call a stored procedure that will collect all the data and then read it with a few lines of code in my code behind. I'm curious to know which of these two approaches, or any other approach, would be the most efficient, elegant, future proof and easiest to test.
I am trying to avoid enabling EnableViewState..Sample code as you can see has 1 repeater and 2 textboxes inside. I bind the textboxes at page init. After a postback I want to get the updated data from the client & save in a db. The Request.Form contains the data keyed with autogenerated client ids but the repeater has 0 items after the postback. So my options seem limited to.a. Enable viewstate so I can pull the data from the repeater using Control.Find(...)b. iterate through Request.Form and find my textbox values...ultimatly the goal is to to render data from a datatable to some textboxes, allow the user to make changes then save these changes. I'd like to avoid viewstate if there is a clean alternative..ASPX:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Foo.aspx.cs" Inherits="Ads_Foo" EnableViewState="false"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-
we have a program that we work with with in 2 different locations, both of the program instances must share the same database.what i did is to open Web Sharing folder on our server then i added on both computers this folder to their "My network places" and direct both of application to this folder which contains the database.this is how i direct the program :
Code:
D:WNKKWnkk.exe \MyServerktest nk2008
it all works fine but there is one problem, the data pulling is pretty slow when it shouldn't we have 100MB download / upload on our server and over 10MB dl/ul in our office.
some pointers:i added the shared web folder to one of our website directory and thats mean that the port the program is using is 80 is port 80 is slower then others?
The DoctorGen Table has primary key DocId and Doctors has Keys set on DocId and MemId. I want to get all records from DoctorGen where UserID = @UserId even if there are no matches in the Doctors Table. I'm not getting any records.
I am pulling a date from an Access Database and inserting into my Dataset. I am assigning it to "myDate" and then assigning it to my SQL parameter @StartDate.
When I run my ExecuteNonQuery I get a null value in my SQL database. There are no null values in my access database. I must have the syntax wrong.
I have a select statement that is supposed to be filling grid with information from an income table. It's only supposed to pull if the income is from the current fiscal year or is less than 1 year old. Currently, what it does is pull multiples of rows and also rows from past income years but only if there is a mixture. For instance, if a person has income from 2005 and 2010 what it will show is this
Income 2005 Income 2005 Income 2010 Income 2010 Income 2010
Does anyone know what I've done wrong? BTW, those results are exact, old income is shown twice, current is shown 3X
I have a page that displays updated data every few seconds but instead of pulling data from database, I would like DB to push data only if the data has been changed. Is that possible?
I am having a slight issue with grabbing data from my masterpage into my content page (as a whole).
I have generated a public property for the my textbox and the contentpage can see this public property. But it comes across empty (even from within the masterpage). Now I guess the problem is with the property itself (possibly). It also shows as empty when I response.write it's value to the page.
Even when I call the value of the property in the masterpage it comes across as empty. The way I have this setup is that a textbox named pageTitleField has it's value updated from an iframe. All is working well and the textbox has its value updated correct upon iframe content changes. This is great. Now I just need to pass this textbox value into my content page and then set it as the document title.
see my code thus far.
My MasterPage
[Code]....
My MasterPage CodeFile
[Code]....
My ContentPage
[Code]....
My ContentPage CodeFile
[Code]....
I know the public property is being seen from the content page because if I just do a Response.Write(Master.GrabPageTitle) I see System.Web.UI.WebControls.TextBox appearing as the output of that property. So it appears hat the textbox value is not being captured in the public readonly property.
I'm creating a pseudo invoicing system. I've got a webform where users can pick such informaiton as days, companies, etc to pull the information to create the invoice for and then they click a submit button. I'm wondering what the easiest method would be to get this information. I've had success with such commands as:
but how can you pull this information through the SQLDataSource tools? When I choose to alter the "WHERE" in the sql clause to a control items in the previous page are not accessible.
I have two web forms. There is a Button Control on one web form and One DropDownlist on another web form which binds "States" on Page_load().
If i click on button in the first web form which pulls out one state (for ex: VA-Virginia) but it should be highlighted and displayed in the dropdown of next web form.
My company uses SharePoint 2007 as a CMS. We have a set of publishing sites. When servers go down, we would like to apply a status message. It doesn't have to be automatically applied, just would appear on first load (if a message exists) or a subsequent refresh. Here's how we would like it to work:
- Status message is located in a text file on the server.
- When a page loads, we would like each it to check to see if there is anything in the text file, and if so, display the message on the page.
- If the text file is empty, we would like it not to display anything on the page.
I can think of a few different ways this could be accomplished using PHP or something, but I'm at a loss as how to do it within SharePoint. Ideally we would be able to place such a block of code into the masterpage.
