I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
item.Attributes.Add("title", someotherdatabasefield);
The end result would be something like this where the text for 'title' comes from the database
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>

When designing an rdlc report using the VS 2010 report designer, report items such as charts demand a dataset. After designing the report, I add a ReportViewer to a webform, and it demands all of its own datasources. How do I hook up the DataSet I have coupled to the report without duplicating the DAL functionality in the viewer page?

View 2 RepliesThis issue has stumped me for a while. Hopefully someone here can give me some insight.
When my site runs the following code it works just fine 99% of the time.
[Code]....
The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types. Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds.
When I run the exact same query in the Management Studio query window it takes 1 second.
what I can do to get the same performance from .Net as I am getting from Management Studio?
I have inherited an ASP.NET/C# project written way back in .NET 1.0. I started programming in .NET 2.0, so some of the antiquated concepts are foreign. I noticed that 80% of the pages have the following snippet or something similar:
#region Component Designer generated code
//Required by the Web Services Designer
private IContainer components = null;
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
connSQL = new System.Data.SqlClient.SqlConnection();
connSQL.ConnectionString = Inventory.Properties.Settings.Default.connectionString;
}
/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
if(disposing && components != null)
{
components.Dispose();
}
base.Dispose(disposing);
}
#endregion
Although this area is hit in the page load process, commenting it out has no obvious effects on the web page. I can guess that if the connSQL object is used and not initialized elsewhere, then problems can come up, this just hasn't been the case. So, my question is where does this designer generated code come from? I've never seen in it the code behind. Is this another .net 1.0 thing?
