[Code]....
this is the code for login.aspx.vb it checks the username and password in the database and redirecrs to respective page on the basis of rows returned. i'm having problem in finding a right function in the sqldatareader namespace so that it counts the number of rows affected.
When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

I have a data table called Songs It has SongId as Primary Key of type INT SongName of Type VarChar UserId of Type Int. I simply want to check how many entries are in the Table already by The UserId before they insert more. So If there are already 3 songs by that User, I want to stop the insert process and warn them they have the maxium already. I think i am halfway there already using code below but problem is that UserId is of Type GUID, and not Int so I am missing something. On my Aspx, Page, I have a DetailsView for the Database Insert. I also have the following code using BusLogic Layer and DAL
SongsBLL
public int ScalarQuery(Guid ArtistId)
{
int returnValue = ScalarQuery(ArtistId);
return returnValue;
}
Code Behind ASPX page
This in in DetailsView_ Item Inserting Event
SongsBLL number = new SongsBLL();
currentCount = Convert.ToInt32(number.ScalarQuery(currentCount).ToString());..........

View 2 RepliesI'm creating an ASP.NET/C# page where a user enters an ID at the top of the page, and when they press Submit, the page posts back and displays the data. Right now, the data fields are displayed at all times - even when the page loads and no search has taken place. This is not ideal as when they navigate a Menu with a MultiView I have made, some errors will come up. Plus it's obviously not good practise.
Is there a way I can hide all these elements (they are DetailsViews and GridViews, plus the MultiView and Menu) if the SQLDataSource is blank? So if the search returned nor esults, or no query has been executed yet.

I have a Gridview and I want to return the number of rows (excluding header row) in it into label1.text.
How to write this code ?
I am using a grid view and a textbox(out of gridview to display the total rows in gridview) , i am doing Paging in GridView , and pageSize is set to 5 ; so far i did this
protected void ExistingMappedGrid_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
totalRowsLabel.Text = "Total " + ExistingMappedGrid.Rows.Count + " records.";
}
it shows the number of records , but not total ! it shows only the records displaying on the page .
e.g.
if i have a total of 8 records , not page index works and shows 5 rows in gridview and other 3 rows on 2nd page index , but if on first instane page shows 5 records in gridview then textbox shows 5 and when i click on second page index it shows 3 rows ( THAT"S NOT WHAT I CODED AND NOT NEEDED ) i want total rows to be shown
I am trying to retrieve the number of rows from a stored procedure. I was trying to use @rowCount as an output parameter in my stored procedure but every time I use that SqlDataSource1 won't retrive me any data. Once I removed @rowCount from my SP I get all the data but don't know how to retrieve the Total number of rows :(
I was trying to do this:
protected
void SqlDataSource1_Selected(object sender,
SqlDataSourceStatusEventArgs e)
{
// lblTotalRows.Text = (string)e.Command.Parameters["@rowCount"].Value;
}

I have the following problem, i am using gridview to display some table info,, and during RowDataBound event i am binding another DataList control placed on gridview template column,,, the problem is that the DataBind() event of the gridview gives "Index 1 is either negative or above rows count." error.
I debugged alot,, when you disable the DataList binding it works,, but why the 2 not working together i dont know!!.

I am trying to show as part of the Gridview table the amount of records found as a total in one of the Gridviews rows. I have some code which does add a row to the Gridview but it does not seem to be counting the number of rows it just shows 0 all the tim. Does anyone know why this might be? you can see the count "visitCount" and the dt.Rows.Add but it doesn't increment

I got below data on my listview:
id salary extra_salary total_salary
1 1000 100 null
2 2000 50 null
on my program, i have count button on below listview, when user click that button, system will auto count salary + extra_salary and updated into total_salary...
I have been looking at this article: [URL] However, I have a question: Can't this be used with a sqldatasource, instead of binding the gridview behind? If so, how?
