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 .

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)

how would I construct a sql query and display them on asp.net?
I have a problem that I cannot seem to resolve. We are using an access database to store data from a Quality Assurance Tool. I need to calculate an average on a specific column in the table, however the SQL statement needs to count the number of records that contain "0.1" and divide it by the total number of records in the table. This data is then displayed in an ASP Page.
The field name is 1.
Here is the SQL:
StrSQL = "(Select Count([1]) FROM cservice Where [1]=0.1) / (Select Count([1]) FROM cservice) As questaverage "

View 9 RepliesI have the following search query
// GET /Home/Results/
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Result(string searchtext)
{
var search = (from n in _db.NewsItemSet
where n.headline.Contains(searchtext)
orderby n.posted descending

return View(search);

The search works and displays a record if a record containing a keyword exists, I am struggling however to implement a feature where when the search is returned it says for example:
0 news items found
N news items match your search criteria: 'string'" displayed

In my asp.net application, users are allowed to enter values into textboxes only from popup windows, so i have set the textboxes to readonly=true; this works fine for me until the first the record is saved. when the record is retireved from database and user updates these textboxes from popupwindows and tries to save the record, the record is never updated, i know the reason because textboxes with readonly cannot be changed on the clientside.
how to allow users to update the records for the textboxes with readonly property set to true.
