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 am creating a web app that using a DataList for display and editing purposes. A datareader is used to populate the DataList. 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 gridview and which contain checkbox field too.If the checkbox is clicked and then delete button click, relevent record is deleted.This delete function is working properly.
problem Even though record is deleted,it does not affected in gridview.Deleted record is still remaining in the gridview.What will be the way that should I follow solve this problem?
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.
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 have an admin page in which I need to change the list whenever a user signs up on our web site.How can I put and event to MySql database so that whenever the count of a table row changes it refreshes my update panel for me to see the new user.
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?
<asp:SqlDataSource ID="totalcount" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT COUNT ([CID]) FROM [WWAMembers] WHERE([CID] IS NOT NULL)"></asp:SqlDataSource>
how do I get the totals displayed with label or other control?
I'm trying to select a random record from my database and display the details of the record on screen. The table I am using is the aspnet_Users table which as I'm sure you all know holds the details of users. After a bit of googling, I found the following code:-
[Code]....
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 want to insert a new record into the database through gridview.New butoon in not inside the gridview it a diifrebt button.when we click new then it show a new row which is blank. another button is save when we click save it will save the data into database
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.
I am trying to update record via stored procedure, but i got error at very start point. Problem is when i click on Edit link button within the Gridview it produce error.
I can populate values from database fine but its produce error when i click on edit link button. see the code below.
Incrementing and decrementing a count table by button click, when a user clicks a button the count table will increment by 1 and when the same user clicks the button the second time it will decrement by 1...
