Forms Data Controls :: Pulling Data From Gridview To Use In Same Row

Oct 7, 2010

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.

Forms Data Controls :: Pulling A Value From A Gridview?

Jun 28, 2010

I'm trying to pull a value from a Gridview so that I can create a running subtotal. I've looked at a number of examples but they all seem to fail.

Why does this not work? Each and every reference I try to make to the cells "value", comes up null.

Sample code1:

[Code]....

Sample code2:

[Code]....

In sample code 2, I get the "header text" for the column...but I know the value in the cell...so it fails on a data conversion.

Forms Data Controls :: Pulling The Value Of A TemplateField From A GridView?

Nov 23, 2010

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.

ASPX:

And here's the Code Behind:

No design time errors reported but here's the run time error:

Object reference not set to an instance of an object.

On the following line:

DataSource Controls :: Unique Numbers For Pulling Data?

Feb 3, 2010

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.

DataSource Controls :: Storing And Pulling Data In DB To Get Google Map Location

Jul 22, 2010

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?)

DataSource Controls :: Appending Data To An SQL Server Database After Pulling From An ODBC?

Jul 15, 2010

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 ?

Web Forms :: ObjectDataSource Concept - From Where Data Is Pulling

Feb 17, 2010

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

<tr>
<td>Type of Plan</td>
<td><img alt="Required" src="/Images/arrow.png" /></td>
<td>
<asp:RadioButtonList ID="radioButtonListPlanType" runat="server" AutoPostBack="True" DataSourceID="objectDataSourcePlanType"
DataTextField="PlanTypeName" DataValueField="PlanTypeId" OnSelectedIndexChanged="RadioButtonListPlanType_SelectedIndexChanged"
RepeatColumns="1" RepeatDirection="Vertical" AppendDataBoundItems="true">
</asp:RadioButtonList>
<asp:RequiredFieldValidator ID="requiredFieldValidator10" runat="server" ControlToValidate="radioButtonListPlanType" ErrorMessage="Type
of Plan is required."
SetFocusOnError="true" />
<asp:ObjectDataSource ID="objectDataSourcePlanType" runat="server" SelectMethod="ListPlanTypes" TypeName="Candle.Web.PlanRequest.CommonWeb">

Pulling Data From Website In .NET And C#

Jun 14, 2010

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:

string baseUri = String.Format("http://www.rogersmushrooms.com/gallery/loadimage.asp?did={0}&blockName={1}", id.ToString(), name.Trim());

// 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();

C# - Methods Of Pulling Data From A Database

Dec 21, 2010

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.

C# - Pulling Data From Repeater With EnableViewState=false?

Sep 19, 2010

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-

Pulling Similar Data From Multiple Information Sources?

Feb 1, 2011

So I have been trying to follow serenarules posts about persistence layers, but I seem to be missing something.

The persistence layer is an architectural layer whose job is to provide an abstract interface to information storage mechanism(s).

This makes sense to me, but I am still having a hard time with this.

So in what cases is this necessary? When you are pulling similar data from multiple information sources?
