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 executed my query in VB with:

I now want to count the number of returned rows so that I can say:IF rows_returned = 1 then login else deny

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 ?

View 1 RepliesI 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 viewing items returned from a dataset in an Infragistics chart control. My problem is that due to a weak point in the control, I am left looking for a way to manipulate the height of the chart based on the count/number of items returned by the ObjectDataSource(DataSet).
Does anyone one have an existing C# sample they could let me view of accessing the count of records returned within the code-behind of a page that I could then use within a case statement to set the hight of the control?
Using C#, how can I check the total number of rows returned from a database when using a Repeater? The reason I need to check is I need to alter the presentation of the data when there is only 1 row returned.

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;
}

This in in DetailsView_ Item Inserting Event
SongsBLL number = new SongsBLL();
currentCount = Convert.ToInt32(number.ScalarQuery(currentCount).ToString());..........
