Using A Label To Refresh When A List Item Is Selected
Aug 3, 2007
Hey,
I have a SQL database that has a list of data,
the table is called books,
there's a column called book and one called author
On the front end, I also have a drop down menu that is populated with the name of the books. What I want is that when a book is selected, a label is automatically generates the author. for example, Harry Potter and the chamber of secrets is selected...the label displays J.K. Rowling. All the data is already in the database and I have had no problem getting the name of the books displayed in the dropdown menu.
Can anyone point me in the direction of a good do it your self tutorial?
Thanks!
-Ian

SqlCeConnection cn = new SqlCeConnection("Data Source=\Program Files\test\tel.sdf");
try
{
SqlCeCommand cmd = cn.CreateCommand();
cmd.CommandText = "SELECT * from phone where PhoneNo = '0912312345'";
SqlCeDataAdapter adp = new SqlCeDataAdapter(cmd);
DataSet ds = new DataSet();
adp.Fill(ds);
this.dataGrid1.DataSource = ds.Tables[0];
label1.Text =Convert.ToString(????????????);
label2.Text =Convert.ToString(????????????);
}
finally
{
if (cn.State != ConnectionState.Closed)
{
cn.Close();
}
}
I can show the result in the DataGrid1
however, I want the label1 to show the Name,
and label2 to show the phoneNo.
how to do in here,
label1.Text =Convert.ToString(????????????);
label2.Text =Convert.ToString(????????????);
thanks

I'm using a form that has a dropdown control. This dropdown control has items that can be selected that serves as a filter for displaying results on the page that is returned from a stored procedure call. I'm having trouble finding a way to execute the stored procedure to display the filtered results everytime a different item in the dropdown gets selected. Currently, the form does get submitted and the selected item does get saved, but the stored procedure never gets executed on a postback. Any ideas on resolving this issure? Your help is much appreciated.

I am having issues where the PowerPivot Field List does not refresh once I add a new table/field then select Refresh All under Data. I have to refresh every single PowerPivot Field List so they are all refreshed. ("PowerPivot data was modified" message). This doesn't happen at first but once the model is built on it tends to happen.I'm on Excel 2010 PowerPivot 2012 SP2 32bit. I have Windows 7 64bit and I'm wondering if the bitness inconsistency is an issue.

write a query that lists item, mfg serial number, and inspection date. The caveat is that, where there is more than one record for an item, he only wants item listed once. For example:
PartNumberInspectionDateManufacturerSerialNumber

3L115931/28/2014009VAS206-1

Dear all,
I am trying to create a recipe database and one of the funtions is to generate shopping list based on the selected recipes.
at the moment, I have a table --recipe, a table--ingredient, and a cross
over table between these two, reIng.
Does anyone know how can I write a procedure with cursor that no matter how
many recipes the user selected, a list of ingredients will be created based
on that? Another things I can't solve is if an ingredient appears twice, how can I make them sum together..
I can write a simple procedure with one parameter so that I can get the ingredients for a certain recipe.( the parameter is the recipeID ). But I get struck when the possibility is that user will select more than one recipe and
wish to get a list of the ingredients. should I use a cursor to do that? Or I should create a temporary table to store the selected recipe?
THanks for your help!

I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?

Using SSRS 2008 r2...I have a report with a single-value parameter and three multi-value parameters, Class1, Name2 and Name3. I'm hoping for an explanation to one thing that I'm seeing and information on a second thing.
Class1 and Name2 both have the (Select All) parameter selected but Class1 is displaying the concatenated parameter variable list whereas Name2 is showing Null. Why is that? If anything, how can I get Class1 to be similar to Name2 and show Null?But my desired wish is to have Class1, Name2 and Name3 display the text"All Selected" when the parameter (Select All) is chosen.

Hi,
Here's my problem. I have 2 tasks defined in my Control Flow tab:
EXECUTE SQL--------->EXECUTE DTS 2000 PACKAGE
When I attempt to run it, by right-clicking the EXECUTE SQL task, and selecting "Execute Task", it only runs the EXECUTE SQL part (successfully), and does not "kick off" the EXECUTE DTS 2000 PACKAGE, after it is done running (even though it completes successfully, as shown by the green box).
Yes, they are connected by a dark green arrow, as indicated in my diagram above.
Why is this?? Am I missing something here? Need help.
THANKS

I am having trouble finishing the last bit of a report. The report shows orders that customers have placed that contain 0 promo items, All promo items (all items in order are promo items), and a mix of promo and non promo (at least 1 promo item and 1 non-promo item). Ive simplified this a bit for ease of understanding but lets assume we have 2 tables: A Promo table that contains the items on promotion and the dates that promotion is valid, and a Sales table, that contains the order number, order date, and sku ordered.
I've already written code that finds orders that have at least 1 promo item in them, and using that, I can determine what orders have 0 promo items in them. Where I am stuck is taking the orders that have at least 1 promo item in them, and separating them into orders that have only promo items, and those that have both promo and not promo items in them. Also, there are several promos throughout the year (called "Offers") so in my code below, you can see 2 different Offers ("JF" and "MA") with their corresponding dates they are valid. They will never overlap. My results also have to be split out by Offer so management can look at the results of each offer separately. Here is some code:
Code:
create table #Promos (
Offer varchar(2) null,
SKU int null,
StartDt date null,
EndDt date null
[Code] ....
So my results should show OrderNo A1111 in the Promo and No Promo group because of SKU 5 not being promotional during the time that order was placed. OrderNo A2222 should be in the Promo Only group because both SKUs on the order were promotional at the time the order was placed.

I have a Report that has a document map Label in the Report which I need to remove.
However as the report has over 50 text-boxes I am having difficulty locating it.
I have had a look at the XML but that does not seem to indicate the offending text box.
Any advice would be greatly appreciated.

Hi,Just a little question...Is it possible to link a SqlDataSource to a label without using a repeater or a formview?I just want to select one column from a single row in a single table and sending the value to a label.The code would be something like this :<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" SelectCommand="SELECT name FROM Page WHERE idPage = 1">
<SelectParameters>
<asp:Parameter DefaultValue="1" Name="idPage" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("name") %>'></asp:Label> So, what can I add in the label properties or in the codefile to make this work if it is possible ?Or am I obliged to "hard code" it in c# with an SqlConnection, a SqlCommand and a SqlDataReader ?Thanks in advance...

A SQL Server 2005 stored procedure expects a parameter UserID depending upon which it retrieves the no. of records & OrderIDs corresponding to the UserID from a DB table (note that OrderID & UserID are two of the columns in the DB table). So for e.g. consider a user whose UserID=6 & the DB table has 3 records where UserID=6. In other words, there are 3 OrderID records of the user whose UserID=6, say, OrderID=8, OrderID=17 & OrderID=29. The stored procedure will finally return 2 columns - the OrderCount (which is 3 for UserID=6) & the OrderID (which will be 8, 17 & 29 for UserID=6). This is the stored procedure:ALTER PROCEDURE dbo.OrderCount @UserID intASDECLARE @OrderCount intSET @OrderCount = (SELECT COUNT(OrderID) FROM NETOrders WHERE UserID= @UserID)SELECT @OrderCount AS OrderCount, OrderIDFROMNETOrdersWHEREUserID = @UserIDIn a VB class file, I am invoking the stored procedure in a function named GetOrderCount which returns a SqlDataReader back to the calling ASPX page. I want the ASPX page to display the 3 OrderIDs of UserID=6 in a Label control. Unlike the DataBinding controls like DataList, DataGrid, Repeater controls, the Label control will not automatically loop through the recordset. So I tried to accomplish this using a For....Next loopDim i As IntegerDim sqlReader As SqlDataReaderiUserID = Request.Cookies("UserID").Value'ShopCart is the name of the class in the VB class fileboShopCart = New ShopCartsqlReader = boShopCart.GetOrderCount(iUserID)While (sqlReader.Read) If (sqlReader.GetValue(0) > 1) Then pnlLinks.Visible = True For i = 1 To sqlReader.GetValue(0) lblLinks.Text = sqlReader.GetValue(1)(i) Next i Else pnlLinks.Visible = False End IfEnd WhileBut this generates the following error:No default member found for type 'Integer'.pointing to the linelblLinks.Text = sqlReader.GetValue(1)(i)in the above shown ASPX code. Can someone please correct me & suggest how do I loop through the recordset so that I can display the records in a Label control?

Hi all,I would like to do something I thought was simple but I can't seem to figure it out. I would like to bind the Text properties to two labels to the columns in an SqlDataSource, much the same as you can bind a listbox to a SqlDataSource.Is this possible?The reason why I'm trying it this way is because I originally used an OleDB connection and datareader, but it doesn't seem to work on our service providers server (keeps saying that it can't find the database) even though it works on the four other server's I've tried. It definitely connects to the database when I use the SqlDataSource on a listbox control, but it fails when I use the same connection string with the OleDB connection.Is this the best way to go about it, or should I persist with finding the OleDB/datareader (the service provider has been no help at all). Thanks.

Hi all. I have a label on my page and I want to bind it to a field in a table. The catch is that I want to bind it to the last row in the table. I think I can use the custom binding, but I don't know how to bind to the last row. Any Suggestions ?
p.s. The page is tied to an SqlDataSource that retrieves the data from the above table.
Thanks in advance.
