C# - How To Display Elements Only If SQLDataSource Has Rows
Oct 8, 2010
I'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 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 a large XML file and want to display out to the webform. So instead of parsing each xml node for the information, is there a quick way to display out the whole xml file to the webform without showing the xml element (display data only)?

I'd like to display certain elements of my page after an interval. I've tried using the 'UpdatePanel and Script Manager', but it seems to Refresh my page after each interval.
How do I prevent that from happening?
There are 3 parts that I want to display, each after 1.5seconds (Div with large letters "Success" (Will happen after a Page.PostBack), Div that Displays Comparisons, Div that Displays the Sample)
Is there a way to write the code inline, so when the page loads the timer intervals dont reload the page?

I have a website using .Net framework 2 on a dedicated server who's display periodically corrupts - typically after heavy traffic numbers to the server. I can correct the problem simply by uploading a batch of user-controls to the server, or recycling the memory pool.
Has anyone else seen this type of effect before, where the display of data-driven elements of a website corrupt?

I am looking to 'hypothetically' post nine rows of data with column headers for 15 different columns. That would be too many textboxes. All the data is directly calculated in VB.net. I want to insert some sort of spreadsheet-type deal with the tool "Table" or something I heard about "Gridview?".

I have a number of columns and a long statement that I need to display on Grid. Is it possible to display data of single row from a table into two rows of Grid? I would like to display the long statement on the second row. Some of these columns need to be editable.
if .NET grid or Ajax or some Free source exists which I could use.
I could use VS 2005/VS 2008 for the purpose.

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?

I need to expose a Web service which will provide an array/DataTable of 20 rows (average) of data - certainly no more than 100 rows would ever be needed. The largest item in these rows would be a date.The Web service would be called by a separate Web site in order to display these 20 (approx.) rows in a GridView/DataView. I would have to be able to dynamically choose which domain to go to and find the Web service.I would possibly have to secure the Web service with a password but this is not vital (possibly with soap headers over https).
My question is what technologies should I use to create this Web service? I know enough about .asmx Web services to struggle through and get this working, but should I get a book on WCF and learn that instead?I use AJAX and jQuery so am also wondering if I should be using one of those client side, to call the Web service and populate the grid?

<asp:ListView ID="ListView1" runat="server">
<LayoutTemplate>
<ol>

</ol>
</LayoutTemplate>
<ItemTemplate>
<li>
<%# Eval("PersonName") %>
<%# Eval("PersonAddress")%>

The problem is the address is not aligned depends on the person's name length.

I have the following fields in an Appointment table:
ID(PK), TeacherID, DayID, TimeslotID, ParentID, StudentID, Remarks & Editable(bit, Default value=1)
I am developing an application to allow parents to book appointments to meet the child's teachers.
It is compulsory for parents to meet child's mentors, hence Appointments to meet class mentors are already pre-booked in the Appointments table.
Parents could still book appointments to meet other subject teachers. I have a column in my gridview to show parents the list of booked appointments. Parents are allowed to change the Appointment timeslot for an appointment they booked and are not allowed to change appointment time for pre-booked appointments.
Under the Remarks colum, it is stated that the following appointment is pre-booked by class mentor.
How do I make only those pre-booked rows read only since all the appointments belonging to a parent is under one GridView.
I found an example, but this is to only make the 1st 3 rows read-only and I don't think this is in VB coding. I'm usingASP.NET VB coding.
