Small change in the tmpform1 form

private void tmpform1_FormClosed(object sender, FormClosedEventArgs e)
        {
            if (PageCount > 0)
            {
                tmpform1 frm = new tmpform1();
             frm.PageCount = PageCount;
                frm.Show();
            }
        }

Not like that i will have 2 buttons on my form like Save and cancel. For both buttons i have to handle for suppose if i enter 3 a form will appear if i click on cancel with out submitting data itr should be closed or hide and the other should open with the same content like that for save if i click on save the data should be saved and again it should show with respect to the text value entered

What is the functionality of Cancel button click. If u r closing the form, then automatically it will call as per ur requirement. No need of any coding.

private void btnCancel_Click(object sender, EventArgs e)
{
this.Close();
}

Have u declared the PageCount property as public in 2nd form.

from the first form did u set the PageCount like this.
2ndForm frm = new 2ndForm();
frm.PageCount = this.txtPageCount.Text;
frm.Show();

Still u r getting error, pls attach ur code.

But in the main form where i am forwarding the text box value it is raising an error 'System.Windows.Forms.Form' does not contain a definition for 'PageCount'
Marimuthu Arigovindasamy16y ago
if u r using 2005, then u have to decalre the prperties like this.
private int _pagecount;
public int PageCount
{
get
{
return _pagecount;
}
set
{
_pagecount = value;
}
}

Hi i am getting an error as

'ACHWinapp1.tmpform1.PageCount.get' must declare a body because it is not marked abstract or extern
Marimuthu Arigovindasamy16y ago
Yes, in the 2nd window forms (Already mentioned in my prev comments as new window code. No neeed in 1st window form)
Dorababu Meka16y ago
We should set an accessor in the page right. Like
in the page that we are wishing to transfer
public int PageCOunt
{
get;
set;
}
Marimuthu Arigovindasamy16y ago
my understaing is, when u enter 2 or 3 in the textbox, that time the new window should open.
frm4.PageCount = Convert.ToInt32(txtPageCount.Text);

If u want to open the window after leaving the textbox, pls use the same code in that event. (Have to use the same code only in ur required event)
Dorababu Meka16y ago
In the text changed event i can not handle Page count
Marimuthu Arigovindasamy16y ago
Try the below one.

Parent window code:

private void tbPageSize_TextChanged(object sender, EventArgs e)
{
//for (int i = 0; i < Convert.ToInt32(tbPageSize.Text); i++)
//{
Form4 frm4 = new Form4();
frm4.PageCount = 2;
frm4.Show();
//}
}

New window code:

private void Form4_Load(object sender, EventArgs e)
{
PageCount = PageCount - 1;
}
private void Form4_FormClosed(object sender, FormClosedEventArgs e)
{
if (PageCount > 0)
{
Form4 frm4 = new Form4();
frm4.Show();
}
}

public int PageCount
{
get;
set;
}

Hi can i handle like this not showing all a time if he click on save then i would like to save that form and would like to display another like that
Marimuthu Arigovindasamy16y ago
Try the below one

Note: Validate the textbox value whether it's an integer or not

private void tbPageSize_TextChanged(object sender, EventArgs e)
{
//Validate the text box value for integer
for (int i = 0; i < Convert.ToInt32(tbPageSize.Text); i++)
{
Form4 frm4 = new Form4();
frm4.Show();
}
}

And another help is if i enter the value as 9 i would like to prompt the same form for 9 times and then redirect to another form.
