View 8 RepliesWeb Forms :: Insert Object Into Database
Feb 8, 2010How do you insert an object into a database, here is the object from the class:
public static Int32 InsertBaseCar(BaseCar theCar)
{
Int32 newBCarId = 0;
try
{
SqlConnection cn = new SqlConnection(_connectionString);
SqlCommand cmd = new SqlCommand("sp_InsertBaseCar", cn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@id", theCar.ID);
cmd.Parameters.AddWithValue("@make", theCar.Make);
cmd.Parameters.AddWithValue("@model", theCar.Model);
using (cn)
{
cn.Open();
newBCarId = Convert.ToInt32(cmd.ExecuteScalar());
}
}
catch
{
// write code here.
}
return newBCarId;
}
And here is my attend at inserting the code into the database:
public void InsertBaseCar()
{
BaseCar theCar = new BaseCar();
theCar.ID = Convert.ToInt32(txtBId.Text.Trim());
theCar.Make = txtBMake.Text.ToString();
theCar.Model = txtBModel.Text.ToString();
//InsertBaseCar();
txtBId.Text = string.Empty;
txtMake.Text = string.Empty;
txtModel.Text = string.Empty;
}
ADO.NET :: Return A Single Row From A Database As A Strongly Typed Object?
Nov 10, 2010I have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?

Jan 18, 2010I have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1

View 7 RepliesWeb Forms :: Store Selected Index Of Listbox In Hidden Field And Then Return To That Value On Postback?
Jan 4, 2011I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change
