VS 2008 - How To Add Values Together From Dataset (with A Repeater)
Jan 4, 2010
I've figured out how to use a repeater field, now what I want to achieve is a "total" figure for the column, and this figure needs to appear the footer.
Back in ASP 3.0, I would simply create a variable, and on every step as I looped through the recordset, I would add the current to the variable, including its original value. At the end, I'd have the total. Apparently I can't figure out how to do the same thing in ASP.NET.
What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?
i have dataset containing multiple images in binary format,how i can use handler to display those images from dataset which i am having,without needing to pass id in query string to handler each time?
I am getting Resultset from SQL server2005.It contains 4 tables.
Dataset ds=new Dataset();
ds=BLogiclayer1.TestMethod1(a,b,c,d);. This normal Dataset ds contains Resultset. ( I am working with RDLC reports. I added a Typed dataset to my project. I am using Typed Dataset as report dataset.) I want to add normal Dataset all the table values to Typed Dataset table as rows i. e. only one table in Typed dataset.I am trying like below.
//Typed Dataset name that I have added is salesdata.
iam trying to connect dataset to an sql server 2008 iam using asp.net 3.0 but when i try to add a stored procedure to a dataset it gives an error "An unexpected error has occured" Error message:unexpected error
i dont know what it is i have converted entire asp.net 2.0 with sql server 2005, to asp.net 3.0 n sql server 2008 already configured dataset works fine, it is just that iam unable to add stored procedures to new datasets
how can i format the dataset column of datetime to date only? i only wan to show the date only without any specific format. example, 1/25/2010 12:00:00 AM to 1/25/2010, without doing a .ToString('M/d/yyyy'). because im following the culture set in the web.config.
I need to give users of my asp.net/vb.net web application the ability to click a button which will then send them an e-mail with the contents of a SQL query attached as an Excel e-mail attachment.
I can manage all of this apart from getting the contents of a VB dataset object into an Excel file on my server.
I know how to export a gridview to Excel at the client end, but my boss has been adamant that he wants the button to send an e-mail with the results attached - I have no need to display a gridview at all.
How to export the contents of a datareader or dataset directly into an Excel file at the server side?
i have one dataset that populates some values like value1, value2, value3, value1, value3, etc. And i am showing this values in a dropdown list. But my requirement is that i have to show the same value once. That is the dropdown should be display like this, value1, value2, value3. Not repeat the existing value.
how to retrieve a value from a typed dataset. I am trying to retrieve a value from a row within a row return from a tabale adapter method. Example:
Dim transAPI As New PN_TransactionBLL() Dim trans As PN.RetrieveGEmailDataTable = transAPI.getGEmail(itemtId)
The tabeadapter method retrieves 1 row of data and I would like to pull the values retrived such as "trans.rowproperty"(if thats the correct syntax) where "rowproperty" would contain the actual value returned.
I'm use to programming in vb.net and doing MsReports.I will add a DataSet with a datatable and then I will add a report.I will populate the report screen with the columns from my dataset which will be available in my toolbar on the left-hand side of my screen. It is a basic drag and drop action.I followed my usual steps in asp.net, but when I try to draw the report, I can't find my dataset.
Why is this?The dataset is named: "dsReport.xsd".The toolmenu where I should see this dataset is labeled: "Website Data Sources"
i need to prepare a report as a table. but my table needs to contain data from two schemas. so my doubt is, is it possible to set two dataset names for a table in its property?
I upgraded a project from Visual Studio 2005 to 2008. Now when I'm in the design view of a dataset (an xsd file) and try to add a new column a get an error message:"Failed to add column. The server version is not supported. Only servers up to Microsoft SQL Server 2005 are supported".But if I add a column from Visual Studio 2005 to a SQL Server 2008 database it works fine.
I have a simple .aspx page. I am using VS 2008. I have a microsoft chart control on the page. In the page_load event, I would like to to populate the chart control. I wrote the following code. I can see the data in the dataset. But for some reason, the data is not seen in the chart control.
Code: protected void Page_Load(object sender, EventArgs e) { DataSet adataset; string Sql = "select count " + '|'+'|' + "unit as Tenor, value from qrm.advancecurve order by days asc"; Database db = DatabaseFactory.CreateDatabase("ConnectionString_OracleQRM");
string studentno = "select regno from stu_ref where batch='" + dropbatch.SelectedItem.ToString() + "'"; SqlDataAdapter dastudent = new SqlDataAdapter(studentno, cn1); DataSet dsstudent = new DataSet();[code]....
form the above coding i will get all values form the table stu_ref of regno of student now i need to get the first and the last regno from the table
