I'm trying to give the user the ability to create a new record from the footer row
and my event handler doesn't seem to be working... or maybe I'm going at this all wrong.
The insert button that I enabled in the gridview doesn't work either...checkout the site at http://aisched.engr.oregonstate.edu/admin/courses.aspx
Here is my code in front
and behind:
public partial class admin_courses : System.Web.UI.Page
{
public Table table;
ListDictionary listValues = new ListDictionary();
TextBox textBox1 = new TextBox(); //Name
TextBox textBox2 = new TextBox(); //CR
TextBox textBox3 = new TextBox(); //CourseNum
TextBox textBox4 = new TextBox(); //Dept
protected void Page_Init()
{
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Footer) return; //Escape if not footer
textBox1.ID = "name";
textBox1.Width = 250;
textBox2.ID = "credit_hours";
textBox2.Width = 25;
textBox3.ID = "dept";
textBox3.Width = 30;
textBox4.ID = "class";
textBox4.Width = 25;
LinkButton add = new LinkButton();
add.ID = "add";
add.Text = "Add course";
add.CommandName = "add";
add.Click += new EventHandler(add_Click);
e.Row.Cells[1].Controls.Add(textBox1);
e.Row.Cells[2].Controls.Add(textBox2);
e.Row.Cells[3].Controls.Add(textBox3);
e.Row.Cells[4].Controls.Add(textBox4);
e.Row.Cells[5].Controls.Add(add);
}
public void add_Click(object sender, EventArgs e)
{
Response.Write("you Clicked Add Course!");
if (textBox1.Text != null && textBox2.Text != null && textBox3.Text != null && textBox4.Text != null) {
listValues.Add("name", textBox1.Text);
listValues.Add("credit_hours", textBox2.Text);
listValues.Add("dept", textBox4.Text); //For Visual
listValues.Add("class", textBox3.Text);
}
LinqDataSource1.Insert(listValues);
Response.Redirect("~/admin/courses.aspx");
}
}
