Put AutoPostback=true
In the drop down list. Without that does not fire the onselectedindexchanged="DropDownList1_SelectedIndexChanged"
I hope that help.
Pregunta
I have a drop down list that allows an admin to assign a user to a role and it is supposed to automatically do so when the index is changed but unfortunately its not doing anything until I click a checkbox that is totally unrelated. Here is the code
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
string userName = Request.QueryString["user"];
MembershipUser usr = Membership.GetUser(userName);
ProfileCommon p = Profile.GetProfile(usr.UserName);
var item = ((DropDownList)sender).SelectedItem;
switch (item.Value)
{
case "1":
if (Roles.IsUserInRole(usr.UserName, "Builder") == false)//if the user is not already in the builder role then add them
{
Roles.AddUserToRole(usr.UserName, "Builder");//here we add the user into the builder role
StatusMessage2.Text = "User has been added to the builder role";//Letting the admin know that the user was added to the role
/* Creating a connection to write to a table in the default database */
string connection = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString;
SqlConnection conn = null;
conn = new SqlConnection(connection);
conn.Open();
/* Here we execute the command and add a member into the table */
using (SqlCommand cmd = new SqlCommand())
{
string query = String.Format("INSERT INTO TestTable (testfirst, testlast, testaddr, testmail, testcomp) VALUES('{0}', '{1}', '{2}', '{3}','{4}')", p.fName, p.lName, p.Address, usr.Email, p.Company);
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
cmd.CommandText = query;
cmd.ExecuteNonQuery();
}
}
break;
}
}
And here is where I make the DDL in the aspx page
<asp:DropDownList ID="DropDownList1" runat="server"
onselectedindexchanged="DropDownList1_SelectedIndexChanged">
<asp:ListItem Value="0">Please select from below...</asp:ListItem>
<asp:ListItem Value="1">Builder</asp:ListItem>
<asp:ListItem Value="2">Investor</asp:ListItem>
<asp:ListItem Value="3">Administrator</asp:ListItem>
</asp:DropDownList>
Is there something I'm missing because I thought that it would automatically perform the tasks on selected index changed. Thank you in advance
