I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?

sometimes learning asp.net feels so heavy handed compared to some of the general purpose scripting languages like php. for examples, all i want to do is create a sql connection that pulls a row count and displays that number. I don't need a grid, list, detail page, etc., nothing this heavy... a simply query that will display a simple bit of text. for the life of me I can't figure out how to do it. Using these controls, I'm not in the code behind with the query, so I wouldn't attach this to a label (or would i), and there's nothing i see in the toolbox that does what i want. Perhaps i'm too accustomed to php but it feels like with asp.net, major things are simple, and simple things are hard.

I have the total number of records in the Datalist being displayed in the Footer. In the DataList, I have a checkbox. How can I iterate thru each record in the Datalist to get the number of checkboxes that are checked?

I have a Drop Down List, a GridView and a DetailsView. The Gridview is the master, the details is the records detail view. When we edit a record and click the update button, I want the page to refresh the gridview and detailsview. Right now after clicking the update, nothing happens, it just updates the current details record.

In the GridView_RowUpdated event the e.OldValues.count <> e.NewValues.Count. 1 out of 5 columns has been converted to a template field.

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

I am learning how to use repeater and datagrid. I've been able to update a datagrid successfully. I have two text box, which take an item description and quantity, save them in a database, and display them back in a datagrid whenever the user access the page again. If the user were to enter a value, let say description ='coffee' and quantity= '15', it would save them in the database properly. However, if the user refreshed the page, a second row with the same value ('coffee', '15') is added to the database again. How can I avoid this from happening?

I've built my page and I get no errors which is a great start I just can't seem to figure out how to then display the results of this query on the page. I just want to display the username for the record that is selected.

I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.
