View 5 RepliesI have an html table with rows and cells. And I have dynamically created a label and would like to assign the label to one of the cells of the table. What I am doing is I have a JavaScript which executes a code behind method and it would not accept an already created asp.net label. So I have created the asp.net label programmatically but cant assign it to the table to display the text value of the label. Below is the code:
[System.Web.Services.WebMethod] public static void EndCandiateTest(){
try { totalTestMarks = ts.RetrieveResults();
grade = tsp.RawScoreAndGrade(totalTestMarks);
remarks = tsp.ScoreInterpretation(totalTestMarks);
testResults = "Raw Score: " + totalTestMarks.ToString() + "
Grade: " + grade + " Remarks: " + remarks;
ts.ShowResults(testResults);
} catch (Exception e) {
} }
protected void ShowResults (string results). I want to display this label in an already existing html table.
messageLabel.Text = results;

Is it possible for me to add my Adventureworks database to the App_data folder? I am running a 32-bit XP using SQL Server 2005 Express.
View 2 RepliesI have a dataset that has around 5 rows. I also have another Datarow() array that has an additional 3 rows which I would want to add to the dataset. The structure of both the Dataset Rows and the Datarow arrays are the same.
Do I have to perform a loop on the datatrow arrays and add them one by one? or is there a better way of adding them in one go ?
Basically what i have is a button and i want this button to add value in database, i mean if the value in the database is 1 it adds 1 to it, so that the value becomes 2.
View 3 RepliesTo Add new row to a dataset table, I am using code below. Before adding this how do I check if that row has already been added to the dataset?
Example:
Dim newCustomersRow As DataRow = DataSet1.Tables("Customers").NewRow()
newCustomersRow("CustomerID") = "ALFKI"
newCustomersRow("CompanyName") = "Alfreds Futterkiste"
DataSet1.Tables("Customers").Rows.Add(newCustomersRow)
Note: The table I am dealing with does not contain a primary key!

I created an MDF file in VS 2008 in the Solutions Explorer window and can see the file path for this file as:
C:Documents and SettingsAdminMy DocumentsVisual Studio 2008WebSitesAddSQLRecordsApp_Data

I am attempting to write my very first ASP.NET application, it will simply display the contents of an SQL server database table in a Gridview. This is just a first step, my eventual intention is rewrite a set of VB6 applications I wrote some years ago. But I need to walk before I can run.
I have already created an SQL Server database containing all the tables used by the VB6 applications.
How do I link this database to my ASP.NET application. Previously (on another computer) I have simply opened "My Computer" and then navigated to the .mdf file (e.g. northwnd.mdf) and then dragged and dropped it into App_Data in Visual Studio. However when I try that on my own machine, with my own data, I get an "Access Denied" message.
How can I not have access to my own data on my own computer? What am doing wrong?
I am running Visual Studio 2008 on a Windows 7 Ultimate machine, with SQL Server 2005 Compact Edition (or which ever one installs with VS 2008).
I have one problem with my shopping cart that I really can't figure out all by myself.I want, if a item already exist in the datatable, the quantity to be updated for that item with the new number instead of creating the same item again.I have done a foreach loop because I think that is where I should start.Notes: MyRow[3] is the column holding the quantity.Code:

What I want is their student Id to be input into the advert table when this new advert is created. How is this possible?
I'm assuming I need to use a pivot table from what I've found so far. However, every one that I've seen has not had the date setup like I have.
I have a Gridview on my page which I need to be populated like so
Date NCMR
1/1/10-1/31/10 #
2/1/10-2/28/10 #
I want to do this for 10 months... bottom record being the current month (or last month). I would also like the Date to format to January 2010 I used the above date format because that is how it is in the table. Basically, I need to know how to create the pivot table to search the table for 1/*/10, 2/*/10, etc
I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.
Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:
[code]...
"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.
"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?
I'm trying to update one my my tables from a field in another table.
I have Address fields on both tables and the old table has some addresses I need to copy over (I dont want to copy/paste or type them all in obviously). I basically need to:
