I use a SQLDataSource with a repeater to list movies. But if ma query contains no result, how can I have a label where writing "Sorry, no result."
I try this code :
[Code]....
But I could only see "toto" when i've results and no result... Why ?
I have a query that I want to test the performance of when the query is included directly in the SqlDataSource versus when I call a stored procedure. Does anyone have suggestions on how I would be able to closely watch the actual steps here? I was thinking of turning on tracing and adding Trace.Write for each of the events that fire along the way. This doesn't seem efficient and I wanted to see if there was a better approach.

i have a sqldatasource which will return 1 field (1 row) for an ID. I need to get that result and display it on a textbox. I would do it using a stored procedure (this was already made) but i was thinking sqldatasource is easier. Is there a way to bind that result onto my textbox?
<asp:SqlDataSource ID="ds1" runat="server"

var query = from emp in dbEmp.Employees join dept in dbEmp.Departments on emp.DeptID equals dept.DeptID where dept.DepartmentName.Contains(this.TextBox1.Text) select new { EmpID = emp.EmpID, EmpName = emp.EmpName, Age = emp.Age, Address = emp.Address, DeptName
= dept.DepartmentName };
if (query==null) Label1.Text = "no results match your search";
GridView1.DataSource = query; GridView1.DataBind();
Everything works in the right way, but the label doesn't show the message when query result returns null. The label can show without condition(querry==null). So how to test if a var query result returns nothing?
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
[code]....
However, when I try to access the results I get the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
Upon debugging, there don't seem to be any results returned... but when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
How do I access this result so I can bind it to my fields?

I have a gridview bound to a dynamic query which produces a total row as part of the bound data. I am making links out of some of the cells and want to do a check to see if the bound data matches certain criteria to allow linking to it. My code looks something like this:
[Code]....
What I want is to change the item template to not include the <a href> if the value of the Eval("Category") statement is "Total".
I tried doing something like <% if (Eval("Category") != "Total") { //do something } %> but that throws an error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have a formview in edit mode, with submit button and checkbox. I want to click the button and have it test to see if the checkbox is checked. The ID of the checkbox is "TestCheckBox". I figured it would be something like, If TestCheckBox.Checked then, but if I type in TestCheckBox it says it's not declared, even though it is a control in the formview.

I need to implement simple quiz in asp.net that displays question, its options and user can answer these questions by checking options and submit the result.
I think ListView is the best control to implement in a way that each Item is question and I need to display Option of the question using check box list.
In ItemTemplate, how can I specify such condition that give me the list of options to select for the user for the particular question in the same row. Just like this:
1. Question Text goes here: (Options to select for the user)checkbox1 goes here; checkbox2 goes here
2. Question Text goes here: (Options to select for the user)checkbox1 goes here; checkbox2 goes here and so on

I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?
I having problem binding web service result into a gridview. I using Word Dictionary Web Service for my project. Below is part of my code.
Web References I using is :
[URL]
Protected void Button1_Click(object sender,
EventArgs e) {
DictService ds = new DictService();
ds.DefineAsync(TextBox1.Text);
ds.DefineCompleted += new DefineCompletedEventHandler(ds_DefineCompleted); }
void ds_DefineCompleted(object sender, DefineCompletedEventArgs e){
GridView1.DataSource = e.Result;
GridView1.DataBind();}
The Error i get is : Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.
I am developing web-app in .NET for 5 months (and enjoying it =)) and I am reading 3 books, all of them teachs at least 2 methods for acessing data: ADO.NET and SqlDataSource object.
I am used to work with ADO.NET method because I feel that even if it needs coding by hand, I can separate the SQL routines from the page and I can customize database routines better.
For now I am using DataReader mode because the application and the database is on the same server and there is only 1Gb RAM available so there is no advantage using DataSet on this moment.
Am I thinking this right? There are some things with SqlDataSource that I don't know how to do it well...
For example:
I have a routine that inserts a record on a table then gets the ID of this record using SCOPE_IDENTITY() function of SQL Server, than it uses this ID to insert another record on another table. Because I use a one-to-many relationship on multiple tables...
How can I work this situation using SqlDataSource object, is it even possible?
I have a table with articles. Every article has a column named category which value is either 1 or 2 On my landingpage the article headers are displayed as hyperlinks. All the articles with category 1 will be displayed in a repeater control on the left side of page and all the articles with category 2 will be displayed in another repeater control on right side of page. I know I can bind the repeaters to two different sqldatasource controls with different SELECT statements. But I wonder if I can do this by only using one sqldatasource control, and if this is better and proper way of doing it. If so, do I create a (datatable?) and do the sorting there?

I have an aspx webpage with a databound DropDownList and a databound GridView control. The GridView datasource is using a WHERE clause to return its' data. I.e. The user selects a work area from the DropDownList and members of that area appear in the Gridview. The GridView has 3 columns, WrkArea, LastName and FirstName. The page also has a Button.
What I am trying to accomplish is when the user clicks the Button, the data from the GridView is copied to a separate SQL table. I am working in VB. I have been looking at other posts but have to admit, I am really confused.
