Getting The Total Number Of Records In A Database Table?

Oct 20, 2010

How could I get the total number of records present in a database table through asp.net in VB? I know about setting up and opening a connection. I wanted to loop through records, so wanted to know the number of records present. How could that be done?

Also, I used statements like 'Update' and 'Insert Into' to to change the data in my data source. Like I updated a certain field like this:

ds.Tables("tblUsers").Rows(2)(3) = "xyzzzz"

and then I executed an sql statement on the same field like this:

objCmd.UpdateCommand = new OleDbCommand
objCmd.UpdateCommand.CommandText = "Update tblUsers " & _
"SET City='xyzzzz' WHERE UserID=3"
objCmd.UpdateCommand.Connection = Conn
objcmd.update(ds,"tblusers")
where objcmd is an instance of oledbdataadapter object)

What should I do to delete a record or a field in a data source through asp.net?

Forms Data Controls :: Displaying Total Number Of Records And Select Option In A GridView?

Feb 4, 2010

How to display the total number of records returned in a GridView in asp.net? I want to display it in a label or if possible next to the page index in GridView... And how to provide a select option in a GridView to select all records (It should select not only the record shown in one page in GridView but all records that were returned to the GridView) or one by one record that was returned? These things (for e.g., Number of selected rows) should also be displayed in the label which I mentioned before.

How Do Display Total Number Of Rows In A Table Into A Label

Oct 6, 2010

i use sql server 2005 and Visual Studio 2008.

I am using asp.ne and vb.net for my website.

i have a table with number of rows 50,000.

i want to display the number of rows at my table in a Label when the page is on load.

so can u give me the code or the hint?

my second question is.

my table has around 50,000 items.

and i have a search box, it look like this

str= select * from mytable where item='car'

the item Car is located in my table in row number of 45,000.

i guess when i search from the table where the item is car, then it will search row by rows, then as the number of rows become huge, it will be so late to find the result.

so is there any method how to search from table with good speed of searching?

Forms Data Controls :: Display The Current Page Number And The Total Page Number In The Report Footer?

Aug 10, 2010

I have a web user control with DataList control in it. In my .aspx page, I have a report header, an empty panel as a place holder, a report footer.In my .aspx.vb file, I'll loop through a list of departments. Within each department, I'll load a label to display the department name and the user control for the data, and add both the label and user control to the panel. So there are two variables:
the number of departments and the number of records in a user control.

Now I need to display the current page number and the total page number in the report footer. Is it doable? How? I'm thinking of this approach: declare a page variable count, count the number of department name labels and the number of records in a user control. When the total count reaches a number, such as 20, I'll break the page. This way, I can get the the page current number and the total number of pages. But how to add a page break to an asp.net page?

One of the reports I am creating has dynamic number of columns - a datatable gets returned from the stored procedure, the number of columns depend on the number of items defined in the database (one column for each item, other than some fixed columns). Is it possible for me to use RDLC report to generate a report in this case?
