Hi, I want to create a web form, dynamically- I mean not to add it via "Add Item", but through the code behind in the cs, and then to open it seperately like a new page.
i have tried to create it like a control - form=new form() and etc... but it doesn't work.

Can anyone help me please?
Thanks

You could create html on the fly and show it, but I don't believe you can create aspx pages on the fly.
Since they have to have their backend compiled and that would make for self modifying code.
Maybe there is a way, but it seems like a bad practice to do so.

Thanks for the answer.

Sorry to ditrub you but I have got another quetion;
if I create a new object of htmlform like : htmlform f=new htmlform;
and I want it to open in a new page I mean other browser you in a new window, how should I do it? I tried the onclientClick="open('"+f+"')"; but it opened in the same page, not in a seperate as i wished, and I have also tried the onclient click="window.open('"+f+"')"; and it told me that the page couldn't be find - because it's not in the solution explorer... so how can i manage to open it in a seperate page?
thanks for the help , i really apriciate it

window.open() in javascript I believe is the only way to open a new browser window.
You could make a special .aspx page in your solution, that takes arguments passed to it (somehow) that will generate that page that you wanted.

[Syoam4ka]

alright, but can i make it dynamically via the codebehind? because I want to make a foreach to create 400 new forms and to "add" them to the solution explorer . can I add the form to the solution explorer without going to the add item etc but only by the codebehind?

[Plater]

Uhhh, why exactly do you need 400 forms?
What I ment was you add ONE page to your explorer, then you programattically tell that one what to display and what it looks like and stuff.
That way your javasrcript can reference it with window.open()

aa arlight i got it . and one more question,
how to transfer the parametrs to that page - it's an aspx, I can't create an instance of it in other pages right?(if I need it in Default 3 for example i can't create default4 f=new default4(); right?)

[Plater]

right.
you can either have the static propertes that you can set from anywhere, and that special page reads them when it loads and displays data accordingly
OR
you can try and have javascript pass them in as querystring and your special page looks at the querystring and understands what to do from there.

[Syoam4ka]

ok, well I don't have any idea what it means actually, so can you give just one simple example pleeaasse? of using one or both of the ways you have suggested?

[Plater]

For a javascript something like:
window.open("myspecialpage.aspx?title=fred likes fish&body=this goes in the body");

Then in "mysepcialpage.aspx" you look for the "title" and "body" parts of the query string and do with them as you will.


For a static page, create a static class (or module i think for vb.net....stupid vb...)
And give it like a public static string TITLE and one for BODY or something.
then in myspecialpage.aspx, you look at the values in that static class and do something with them.




You could also store information in the Session[] object and use it accross pages.

[Syoam4ka]

alright, everything is clear now, THANKS, you have really helped me, god bless you.

[Syoam4ka]

when the window.open('default.aspx') is comitted everything in the original page is erased, can I prevent it; how?

[Plater]

window.open() should not have any effect on the page it's being called on.

hi , look I have dynamically created a few image buttons(with a 'for') and i want that while runtime, when the user presses a specific button, to open a new page in which there would be the same image with the same ImageURL I mean, how can I add an event or something , I don't know... I mean I want to activate a method when the client presses the image button - how, this one problem, the next one is that all that happens in class and in a 'for'(see the code below), so I want that in each page opening as you said, to transfer the proper parametrs, I think the best way is thorgh a session but the problem is that there is the for loop, so it creates many sessions and when I transfer the session to the new page I can't tell it which session to use...
by the way that's why i preffered to create an specific new aspx to each imagebutton (if you remember the 400 forms that i told you...)


public ImageButton Introduction(Panel p1,System.Web.UI.WebControls.ImageButton img,DataList dl, DataList DataList1,DataSet myDS,HtmlForm Form1,SqlDataSource SqlDataSource2)
{
string JewelName=this.GetJewelName(myDS,Num);


p1 = new Panel();
p1.Style["Position"] = "Absolute";
p1.Style["Top"] = "" + Top + "px";
p1.Style["Height"] = "" + Height + "px";
p1.Style["Width"] = "" + Width + "px";
p1.BackColor = Color.Gold;
Form1.Controls.Add(p1);

img = new System.Web.UI.WebControls.ImageButton();
img.ID="img_'"+JewelName+"'";
img.Style["Position"] = "Absolute";
img.Style["Left"]= ""+100+"px";

img.ImageUrl = GetImageURLString(JewelName);

img.Style["Top"] = "" + (Top + 100) + "px";
img.Style["Height"] = "180px";
img.Style["Width"] = "180px";
Form1.Controls.Add(img);



Label l1 = new Label();
l1.Style["Position"] = "Absolute";
l1.Style["Top"] = "" + (Top + 50) + "px";
l1.Style["Left"] = "" + Left + "px";
l1.Text = myDS.Tables[0].Rows[Num][1].ToString();
Form1.Controls.Add(l1);

SqlDataSource2.SelectCommand = "SELECT [Jewel_Name], [Jewel_Commercial_Code], [Size], [Price], [Stock], [Jewel_Sub_Type_ID], [Jewel_Extra_Info] FROM [TBL_Jewel_Name] WHERE ([Jewel_Name] = ('"+l1.Text+"'))";

dl = new DataList();
dl.Style["Position"] = "Absolute";
dl.Style["Top"] = "" + (Top + 100) + "px";
dl.Style["Left"] = "" + Left + "px";
dl.DataSourceID = SqlDataSource2.ID;
dl.ItemTemplate = DataList1.ItemTemplate;
Form1.Controls.Add(dl);


ImageButton BtnImg_AddToCart = new ImageButton();
BtnImg_AddToCart.ImageUrl = "~/Photo Jewellery/add_to_cart_button[1].gif";
BtnImg_AddToCart.Style["Position"] = "Absolute";
BtnImg_AddToCart.Style["Top"] = "" + (Top + 250) + "px";
BtnImg_AddToCart.Style["Left"] = "" + Left + "px";
Form1.Controls.Add(BtnImg_AddToCart);


return img;

}

that was in the class.


and this is in the code behind aspx.cs:

for (int i = 0; i < 5;i++ )
{
pi1 = new ProductIntroduction(Width, Top, Left, Height, num);
img=pi1.Introduction(p1, img, dl, DataList1, myDS, form1, SqlDataSource2);

Top = Top + 450;



num++;
}


oh and there is another problem - if I add the event method in the class (not in the cs) there is now session using possibility there right?

I hope and will be grateful if you can help me))
