[RESOLVED] add dropdown and textboxes to a dictionary collection

Hello guys,

I am using the approach to be able to iterate through the textboxes and dropdow list on a page

public static IEnumerable GetAllControls(Control parent)
{
    if(null == parent) return null;

    return new Control[] { parent }.Union(parent.Controls.OfType().SelectMany(child => GetAllControls(child));
}



foreach(DropDownList list in GetAllControls(this).OfType())
{
    //TODO: add values to dictionary collections and append to session object
}

Now, after the loop and getting the values, I need to be able to store the droplist list ids and values into a sesion to be available elsewhere in the application.

Please help.

Thanks

untested, but something like

Dictionary data = new Dictionary();

foreach(DropDownList list in GetAllControls(this).OfType())
{
    data.Add (list.ID, list.Items);
}

Session["DropDownData"] = data;

[RESOLVED] User Login????

i have four pages asp.net (c#)

(1) Login Page (2) MainMenu1   (3) MainMenu2 (4) MainMenu3

i also have sql database name "mydatabase" have three tables 

(1) Student (2) Teacher   (3) Admin

Login page contain 2 textboxes (  textbox1 for username,  textbox2 for password) and login button

i want when login button is pressed then check (match) username and password in three tables (Student ,Teacher ,Admin)

*if user is Student then page MainMenu1 is open

*if user is Teacher then page MainMenu2 is open

*if user is Admin then page MainMenu3 is open

plzzzzzz help me?????

Ok, post your code.  I think it would be nothing more than code behind visibility statements based on

if (!User.IsInRole == "Student") 
   {
   Menu1.Visibility = hidden;
   }
   else
   {
   Menu1.Visibility = visible;
   }

At what stage are you?  Are you in the process of setting up the databases / tables? Or are you having to work with pre-existing tables?

Because if you are just starting, then the suggestion of bbcompent1 is a slick way to do it.  When each user is created, you would want a bit of code-behind to assign that user to one of the three Roles.

Then you probably only only need the tables that come with the asp.net membership, no need to add separate tables for the students, teachers, and admin.

And you only need one page for the menus -- not three -- just showing or hiding them as suggested.

Yes,you should write that code in the search button click event..query the database with the textbox value and bind your gridview.

Hi 

Create stored procedure:

string conString = ConfigurationManager.ConnectionStrings["MyCon"].ToString();

[RESOLVED] How to get new value from text-box in updating profile.??

Hi friends I designed webpage where people can login and after login they will be in profile page and on Profile page where Suppose these information is showing

First Name, Last Name , Email and these information are coming for database according to session

so on profile page there is Edit button when some one click on this so new page will be open where there is Coloumn

First Name:

Last Name:

Email :

and in these coloumn information are showing  which is coming from Profile page because on new page I set some coding so it takes information according to session from profile page problem is now suppose on new page when I am changing information and click
on Save button so information is not changing because text box is taking same value which is coming from profile page .

in short when you open page and some value are showing in text box and you can remove that value and fill new value and save on button so new value is not taking because in text box already value is filled so how I will referesh or do something else that
previous value can be vanish and new value can be taken in text box when I click on save button.

Make sure you are only loading the textboxes from the database when NOT ISPOSTBACK.  On the save button click you should then be able to save the new values in the textboxes to the database.

Yes Joy is right, load the text box in if(!isPostBack) and also have you written the Stored Procedure to update the profile as well?

Hi,

SACHIN2708

First Name, Last Name , Email and these information are coming for database according to session

    {
       if(!IsPostBack)

           TextBox2.Text = Session["lname"].ToString();
           TextBox3.Text = Session["email"].ToString();
       }

in short when you open page and some value are showing in text box and you can remove that value and fill new value and save on button so new value is not taking because in text box already value is filled so how I will referesh or do something else that
previous value can be vanish and new value can be taken in text box when I click on save button.

Make sure you are only loading the textboxes from the database when NOT ISPOSTBACK.  On the save button click you should then be able to save the new values in the textboxes to the database.

Yes Joy is right, load the text box in if(!isPostBack) and also have you written the Stored Procedure to update the profile as well?

Hi,

SACHIN2708

First Name, Last Name , Email and these information are coming for database according to session

so on profile page there is Edit button when some one click on this so new page will be open where there is Coloumn

Refer to the code:

    protected void Page_Load(object sender, EventArgs e)
    {
       if(!IsPostBack)
       {
           //Load values from session to TextBoxes
           //For example...
           TextBox1.Text = Session["fname"].ToString();
           TextBox2.Text = Session["lname"].ToString();
           TextBox3.Text = Session["email"].ToString();
       }
    }

Hope it helps!

Best Regards!

Thanks a lot it works now,

use page not postback in page load event.

if(!Page.isPostBack)
{
// your code
}

[RESOLVED] add dropdown and textboxes to a dictionary collection

Hello guys,

I am using the approach to be able to iterate through the textboxes and dropdow list on a page

public static IEnumerable GetAllControls(Control parent)
{
    if(null == parent) return null;

    return new Control[] { parent }.Union(parent.Controls.OfType().SelectMany(child => GetAllControls(child));
}



foreach(DropDownList list in GetAllControls(this).OfType())
{
    //TODO: add values to dictionary collections and append to session object
}

Now, after the loop and getting the values, I need to be able to store the droplist list ids and values into a sesion to be available elsewhere in the application.

Please help.

Thanks

untested, but something like

Dictionary data = new Dictionary();

foreach(DropDownList list in GetAllControls(this).OfType())
{
    data.Add (list.ID, list.Items);
}

Session["DropDownData"] = data;

Aidy Guided Very WEll.

[RESOLVED] User Login????

i have four pages asp.net (c#)

(1) Login Page (2) MainMenu1   (3) MainMenu2 (4) MainMenu3

i also have sql database name "mydatabase" have three tables 

(1) Student (2) Teacher   (3) Admin

Login page contain 2 textboxes (  textbox1 for username,  textbox2 for password) and login button

i want when login button is pressed then check (match) username and password in three tables (Student ,Teacher ,Admin)

*if user is Student then page MainMenu1 is open

*if user is Teacher then page MainMenu2 is open

*if user is Admin then page MainMenu3 is open

plzzzzzz help me?????

Ok, post your code.  I think it would be nothing more than code behind visibility statements based on

if (!User.IsInRole == "Student") 
   {
   Menu1.Visibility = hidden;
   }
   else
   {
   Menu1.Visibility = visible;
   }

At what stage are you?  Are you in the process of setting up the databases / tables? Or are you having to work with pre-existing tables?

Because if you are just starting, then the suggestion of bbcompent1 is a slick way to do it.  When each user is created, you would want a bit of code-behind to assign that user to one of the three Roles.

Then you probably only only need the tables that come with the asp.net membership, no need to add separate tables for the students, teachers, and admin.

And you only need one page for the menus -- not three -- just showing or hiding them as suggested.
