Hello,

I have a form, which has 20 input fields for name and phone numbers.

ie

"Name1" runat="server">

"Phone1" runat="server">44

 This goes from name1 and phone1 to 20. In my protected void Button1_Click(object sender, EventArgs e) Whats the best way to catch all this values. I have tried using the

1. foreach (string element in Request.Form)

But cant get my way around getting all the names and value pairs

2. Manually catching all the values using

string name1 = Name1.Text.ToString();

string name2 = Name2.Text.ToString();

etc

Whats the most efficient way around this ?

Thanks

Ehi

This code may help you... 

        for(int i=1; i<=20; i++)
        {
            Request.Form["Name" + i.ToString()];
            Request.Form["Phone" + i.ToString()];
        }

But if the text boxes are in a user control or a page using master form you need to use the client id part also in the Request.Form

If any issues please let me know with details.

Hi

If you want this to be name/values pairs then this is best approach

Better formatting:

 Hashtable ht = new Hashtable();

Here is the error message

Line 34:         for (int i = 1; i <= 20; i++)
Line 35:         {
Line 36:             Request.Form["name" + i.ToString()];
Line 37:             Request.Form["phone" + i.ToString()];
Line 38:         } 

Opps Sorry, that was the reply to anzer's message above. Didnt know there would be so many replies in such a such time :-)

So how do i get the values out ?

I tried using

 Response.Write(txt); 

and

 Response.Write(ht); 

But not getting any values out :(

foreach (Control ctr in Page.Controls)

{

if (ctr is TextBox)

{

TextBox txt = (TextBox)ctr;

ht.Add(txt.ID, txt.Text);

}

}

Compiler Error Message: CS0201: Only assignment, call, increment, decrement, and new object expressions can be used as a statement

 Thats just a sample code you should use the values we are getting from Form variables, for example assign the values to some variable.

for(int i=1; i<=20; i++)
        {
            string name = Request.Form["Name" + i.ToString()];
            string phone = Request.Form["Phone" + i.ToString()];
        }
 

or try

for(int i=1; i<=20; i++)
        {
            Response.Write( Request.Form["Name" + i.ToString()].ToString());
            Response.Write( Request.Form["Phone" + i.ToString()].ToString());
        }

afrika. are you still facing issue.

Sorted.

 Thanks. I just didnt get a reply from Abhishek Khanna

Hey afrika

Was away. But you can try my version too, just for fun & learn.

Here is what you can do:

foreach (Control ctr in Page.Controls)
{

if (ctr is TextBox)
{

TextBox txt = (TextBox)ctr;
Response.Write("ID: " + txt.ID + " value: " + txt.Text);
}

}

Thanks

Abhishek
