How to use a ID to display parts of information on 2nd page

Hi forum experts,

I used to use this set attribute to a related model object and then just use the get attribute in Java.

Can this be done in asp.net web form ?

Hope someone can give me an example.

Cos now my problem is that I have different section in a form.

Some form has data that I can draw out using HttpContext.Current.Session.

Some parts of the form require users to enter by themselves.

In addition, I am drawing out the data and auto-populate onto the form - without using HttpContext.Current.Session.

So in this case, how can I pass the data to a page where I can display a ID that is generated for this first form and then I pass it to the next form.

Using this ID, I can display some relevant data like created date, some parts of the user data that is from the section in this form ?

Hi Rashmi,

Perhaps let me tell you what I have attempted so far and can you tell me why the formId just would not appear ?

Here's the helper class which contains the generate form method. I am leaving out all the connection string etc.
public string generateRefNo(){

string newRefNo = "";
string currentRefNo = "";
int generateRefNo = 0;
SqlCommand cmd = new SqlCommand(StoredProc_GenerateNo", con);
cmd.CommandType = CommandType.StoreProcedure;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);

DateTime now = DateTime.Now;
string y = now.ToString("yy");
string m = now.ToString("MM");
string CurrentDate = y + m;
if (dt.Rows > 0)
{
DataRow dr = dt.Rows[0];
if(dr["EMPTID" ].ToString() != "")
{
currentRefNo = dr["EMPTID" ].ToString();
string [] RefNo = currentRefNo.Split('-');
int sno = Convert.ToInt32(RefNo[1].ToString());
if(RefNo[0].ToString().Substring(1,4) == CurrentDate)
{
generateRefNo = 01 + sno;
}
else{
generateRefNo = 01;
}
newRefNo = PMT + CurrentDate + "-" + generateRefNo.ToString().PadLeft(2, '0');
}
}
else
{
newRefNo = PMT + CurrentDate + "-" + "01";
}
return newRefNo;
}
And then I am trying to call this FormNo via this way at the first Form.
if (! PostBack)
{
string EPMTNumber = Request.QueryString["EPMTID"].ToString();
// follows by other methods e.g. like
BindAllDetails(EPMTNumber);
}

protected void btnSave_Click(object sender, EventArgs e)
{
string Action = "SaveUpdate";
string EPMTNumber = Request.QueryString["EPMTID"].ToString();
int status = Convert.ToInt32(ViewState["CStatus"].ToString();
UpdateEPMTRequest(Action, EPMTNumber, status);

if (rbtlistReqType.SelectedIndex > -1)
{
string Action = "Save";
string EPMTNumber;
int status = 0;
EPMTNumber = ph.generateRefNo();
UpdateEPMTRequest(Action, EPMTNumber, status);
Response.Redirect("EPMTDraft.aspx");
}
And then at my EPMTDraft.cs which is the 2nd form there I want to call this EPMTNumber.
"grvBindDrafts" runat="server" GridLines="Horizontal">

"ViewFormNo" HeaderText="EMPTNo" DataNavigateURLFields="EPMTID"
DataNavigateURLFormatString="ePMTNew.apsx?EPMTID={0}"/>
"IssuerName" HeaderText="CreatedBy"/>
"Issuerdate" HeaderText="Created On"/>
How do I do it ?

Hi Rashni,

Do you mind point me to a step-by-step tutorial to do this?

you can use querystring to pass ID from one page to another.

append querystring parameter to your URL like - URL?ID=''value" to first page

then retrieve on second page

string ID=Request.QueryString["ID"].ToString();
