Currently I am developing an ecommerce web site where
1. I choose the Product from a GridView (by pressing Select)
2. This product gets added to a DataView
The problem arises because I have a quantity textbox and wish to multiply the price by the quantity textbox.
How can I extract the price from the gridview to multiply it ? (and then subsequently display it in a label)
I have a datalist that is populated via and SqlDataSource. Code is VB
I am trying to extract two Values from the Item Templete and add them together. Then I want to add a new Label to the item template with the sum of the two added values.
I am able to to this using a GridView but no success with the datalist

i'm currently doing a shopping website. The customer will have to selected the item they want to buy and it will appear in the detail view when they click add in the grid view. I need the info inside the detail view to be insert into a database call Orderlist.
i've try using INSERT INTO OrderList (ProductName, Price,) VALUES (@ProductName, @Price) but it don't seems to work.
Was it because i can't insert it like this as it is detailview? This method can work if is Textbox instead of detailview.
i have a gridview of 8 columns.I need to extract the data row by row from the the first(Message) and the last(phone_no) column and to be inserted into my sql table named massMessage.I have the codes here. Apparently im able to only extract the phone_no. My message wasnt inserted.
protected void btnSave_Click(object sender, EventArgs e)
{
foreach (GridViewRow gvr in GridView2.Rows) //loop through GridView

I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).

I had created the database called train. A train database has a two tables
I'm building an application, my client wants me to create new control using AJAX. This control should look like thisThis control includes price(dolars and cents) and when user clicks on specific price(suppose 95 dolars and 33 cents) this price should jump inside to textboxs(one for dolars and one for cents)Does anybody have a clue how to implement this control creation??

Im writing a bit of code that will extract the contents of a gridview to excel. I have all the parts working except for one. In my page_load i fetch the data from the database and then have the user select some options which filters the data and then the gridview gets populated. The problem im having is that the Response call doesnt seem to get the data from the gridview if i enclose the database fetch command within if not page.ispostback in the page_load
I have some test pages where i just fetched the data from the database bound it in a gridview in the Page_load. then on a button click export the data in the gridview to excel. Works fine if i DONT enclose the fetch command within not page.ispostback but outputs an empty excel file if i do.
Now i have to use not page.ispostback in the actual webpages because the users have to make selections which will filter the original dataset. How do i get this to work?
The page is also implementing AJAX if that helps. Here's an example of what i have:

I have a dataGrid with ButtonColumns in my asp page and I would like to do the following to:
When a row is clicked, I want to be able to:
1 - Hide all rows and display only the clicked row dynamically/on the fly.
trying to loop thru the datagrid and display only the Row index passed by the OnITemComman - but unsure of how to do it.
2 - Extract the row values (all cells in the row) to use as parameters in a query.
Used many ways of many examples but i always get a blank value. Managed to get the button text in the class but i need the full row values not just the cell clicked.
I have a table that includes a state column and a price column.
I am able to obtain the average price from a particular state using:
SELECT avg(Price)
FROM MainTable
WHERE StateId=x
I would like to display the average price from each state. The only way I know of doing this is 50 seperate datasource controls. Is there another way?

I want to sort the string which is in the format given below15% Test;15% Sear;40% Santhosh;30% Jeeson;
The output that I am expecting is
40% Santhosh;30% Jeeson;15% Sear;15% Test;
I wrote the following code but it does not work .
string str = "15% Test;15% Sear;40% Santhosh;30% Jeeson;";
Console.WriteLine(str);
DataTable dt = new DataTable("SortBenchMark");
DataRow dr;
dt.Columns.Add("Weightings", typeof(int));
dt.Columns.Add("BenchMark", typeof(string));
string weightings = string.Empty;
string BenchMarkName = string.Empty;
foreach (object o in str.Split(';'))
{
if(o.ToString().Length > 0)
{
dr = dt.NewRow();
dr["Weightings"] = Convert.ToInt32((o.ToString().Split('%'))[0].ToString().Trim());
dr["BenchMark"] = (o.ToString().Split('%'))[1].ToString().Trim();
dt.Rows.Add(dr);
}
}
dt.AcceptChanges();
DataView dataview = new DataView(dt);
dataview.Sort = "Weightings DESC,BenchMark Asc";
string final = string.Empty;
foreach (DataRow drow in dataview.Table.Rows)
{
final += drow["Weightings"].ToString().Trim() + "% " + drow["BenchMark"].ToString().Trim() + ";";
}
Console.WriteLine(final);
Console.ReadLine();
Can a dataview be declared as public?
Dim dvEditTreatmentType As DataView = New DataView(dsTreatmentEndDate.Tables(0), "IsNull(DialysisEndDate, '') = ''", "", DataViewRowState.CurrentRows)
can this be declared as public Dataview? is there a way to do it?
What is the difference between dataview and datarowview?
What is the use of datarowview?
HOW TO specify which columns are in a DataView from a DataTable. I want to create a DataView, that only has the columns from a DataTable that I choose, and in the order I want.
Example:
// DataTable_MyTable ~~ Column #0 is for ID. I do not want my view to get this column.
// DataTable_MyTable ~~ Column #1 is for TYPE. I want this column to come in 2nd place in my view.
// DataTable_MyTable ~~ Column #2 is for NAME. I want this column to com in 1st place in my view.
DataView DataView_MyView = new DataView(DataTable_MyTable ~~ some how only get the columns I want, and in the order I want ~~);
// DataView_MyView now has only 2 columns.
// DataView_MyView ~~ Column #0 is NAME.
// DataView_MyView ~~ Column #1 is TYPE.
I have a datatable which contains the summery row as well. I just assign the datasource property of a gridview and call databind method to fill and display the records.
Now, when I applied sorting through dataview to the gridview, the sorting happens along with the summery row, which is a normal behavior. As a result the "Total" - column took place inside the data some times. I want to prevent this.
The best way out for that can be done by creating the summery row at grid view row databound. But unfortunately I could not change the datatable as per this requirement.
Can the dataview sorting exclude the last row of the datatable through any process?..
I know how to do this in a datatable but I would just like to learn how to do it in a dataview.
I have a dataview which is used to populate a gridview. It has the following column
userid Location
123 New York
124 Chicago
125 London
Now, I would like to know how to determine the 124 row and highlight it to a blue in a dataview used to populate a gridview. kindly note, i can do this in a datatable but not a dataview. I would like to learn how to do it in a dataview.
converting a DataView to a DataSet?
I have a DataSet 'programs'. I want to sort if before passing it to a user control where it will be rendered.
I created the DataView and sorted it successfully like so:
[Code]....
The line of code to pass my old (unsorted) dataset to the UC is like this:
[Code]....
What is the syntax for passing the dvPrograms to the UC in a similar manner?
I have the following code in place:
[Code]....
and the following stored procedure:
[Code]....
The Dataview control is not appearing when the page is loaded. Has anyone any ideas ?
I have tried the online converters, and none of them that I have tried will accurately convert this. It still tries to add a .Item property to the dataview and that does not exist in c#. I know this is simple...
dv.Item(e.Item.ItemIndex).Row.Item(1)
