Hi All
I am new to VS 2005 and ASP.NET. I used to use Dreamweaver to design but now I am trying VS.
What I want to do is to display data retrieved with a SqlDataSource in a web page. I know how to do it by binding it to the various controls (Grid, DataList, DetailsView, FormView, Repeater.) available but how can I display it without using any of the mentioned (Grid, DataList, DetailsView, FormView, Repeater)?
Any help apprecited.

hi,i have a DB that contains some tables.so i have a radio button group of tow radio button to display a field.now how can i bind this radio button group to this field for updating and insert a new record?for more explain i brought a little of code below: in .aspx page i have: <asp:RadioButton ID="admin" runat="server" Checked="True" GroupName="membertype"
Text="admin" OnCheckedChanged="admin_CheckedChanged" /><br />

I have a block of code that does a Fill() with a DataAdapter, which seems to throw an exception if no values are returned. Then, when I try to bind the DataSet that gets filled, an error occurs, it doesn't even try to bind the column headers or anything.
This process seems to work fine when some rows are found, but it is not always guaranteed that the row count will always be > 0. The nice thing about using the Fill() function, is that it creates all my column headers automatically, so I was just wondering if there's a way to do a Fill() then a subsequent DataBind() to a DataGrid which would automatically format the columns even when no rows are found?
Here's a bit of the source.. if the last line finds no rows, it throws an exception ( I assume this is normal):
strSQL = "SELECT * FROM Prods";
cm.CommandText = strSQL;
da = new SqlDataAdapter( cm );
da.Fill(shelf);
Anyone got any ideas on how to fix this problem?

Hi there,
I'm trying to set an int type attribute to 0 for its Default Value, but it keeps reverting to ((0)). What is causing this?
Every int type attribute on that table does the same. There is one bit type attribute and a bunch of other type of attributes, but non of them are giving me a problem. The table is a copy from another database and I did check all the constraints and properties to make sure they're the same.
Thank you,

Hi All,
I have written a Query and Stored Procedure in SQL 2000 which fetched around 15 Lac data. It takes around 17 seconds to fetch the data in the Query Analyzer. But when i am using the Query/Stored Procedure in the report and I have deployed it in the server. When i am accessing the report in the application it taking around 2-3 minutes to bind the data.
What might be the issue? My tables in the database has been normalized.
Please help me to sort out this problem.

Hi,
Referring to the book "Data Mining with SQL Server 2005" written by ZhaoHui Tang, I created a Mining Structure and a Mining Model with the AMO API after creating Database and Data Access Objects(referred to code lists from 14-1 to 14-6). I added Nested Table by creating a table column and added a key column to the nested table, while the error showed that in my structure the column of the nested table didn't include effective data bindings when processing.
Thanks for any suggestion!
Hi there everyone. I have a stored procedure called “PagingTable� that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see. This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server. The code might look something like this:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
The problem is the stored procedure actually returns two result sets. The first result set contains information regarding the total number of results founds, the number of pages and the current page. The second result set contains the data to be shown (the columns specified). In ‘classic’ ASP I did this like this.
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control. Any idea how I can accomplish two things:
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset
when i do a snapshot i have it set up to truncate before inserting. As a result I'm getting an error saying that it cant truncate a table reference in an indexed view. What settings should i use to allow for a snapshot in this instance? Should i manually drop the databinding then snap then recreate the databinding? there has to be a better way
View 1 Replies View RelatedI am trying to display hirearchical data using data region. For eg. the first level will be a list of customer names. The second level will be a list of Invoices under each customer. The third level will be a list of product names that were sold under each invoice.
I used a list for the data region and in each hireachy, there is a textbox in each list to display the data. I am trying to associate each data region with a datatable (I will provide the logic to populate the datatable with appropiate data). I do not want the ReportViewer to interact directly with a database because this is a 3 tier design and I am using the ReportViewer in local mode. I couldn't find any example of these. Can anybody help? Also I would like to see an example of the .rdlc file in these situation. Thanks very much.

I am using a filter in a matrix control. I would like to display a "No data" type message if no data is present. The problem I'm running into is the base query is returning data, but the optional filter is removing all rows from display.
So using CountRows in the base dataset doesn't quite cut it. Is there an alternative?

Dept/TotalProj
A, B, C
10, 5, 2
I have a table with only one column as
Emp_Name
A
B
C
D

I want to display this data as

Is this possible? I am using SQL server 2005.
Any help is appreciated.
