Hello all,
I havedeveloped an application in which one of my forms adds controls(Label,Button,Progressbar) at runtime;i.e on every click of a button, a Label,a Button & a Progressbar is added in a row shape.
I have set AutoScroll Property of the form to true and also fixedthe form's height & width. When the number of controls(being added at runtime)increase, form sets the scrollbar automatically and i can see allthe controls added no matter how many have been added,thanks to AutoScroll=True.
But those controls which are added after the scrollbar is activated, are locatedwith uneven space between them;i.e. if the scrollbar is activated after 5 contorls are adeed,then the controls being added after these 5 controls are placed with different space with respect to each other.Each row of controls(Lable,Button,Progressbar) is located at different Y location. Why is it happening? It only happens when scrollbar is activated(when form size issmall & more contorls are added).
Thanks in advance

Hi,
You need to calculate the scroll bar y location and subtract it to your control y location.i hope it will help you
if you want to more post some code sample..

thanks Gnanadurai for your quick reply.
You mean i should calculate the new Y location for my next runtime control and subtract it to previously added runtime control? Or you mean to get the Y location of the Form & subtract from my next runtime control?
Please make it clear,thanks.
My whole code to create the runtime controls is here:

//------------Start Code------------

public bool addNewControls(string senderOrReciver, string fromUser, string fileName, string ToUser)

{

try

{

FontFamily ff = new FontFamily("Verdana");

float size = float.Parse("8.25");

FontStyle objFS = FontStyle.Bold;

Font myFont = new Font(ff, size, objFS);

string dname;

string dnameCancel;

if (senderOrReciver.Trim().ToString() == "Sender :")

{

dname = fromUser + fileName;

dnameCancel = fromUser +

"=" + ToUser + "=" + fileName;

}

else

{

dname = ToUser + fileName;

dnameCancel =

"Rec" + fromUser + "=" + ToUser + "=" + fileName;

}

Label l = new Label();

l.Name =

"fileName" + "_" + dname;

l.Font = myFont;

//l.ForeColor = Color.White;

l.Text =

"File Name : " + fileName;

l.Location =

new Point(202, FileNameY + y);

l.Width = 200;

l.BackColor =

Color.Transparent;

this.Controls.Add(l);

Label l1 = new Label();

l1 =

new Label();

l1.Name =

"Sender" + "_" + dname;

if (senderOrReciver == "Sender : ")

{

l1.Text = senderOrReciver + fromUser;

}

else

{

l1.Text = senderOrReciver + ToUser;

}

//l1.ForeColor = Color.White;

//l1.Text = "Sender : " + fromUser;

l1.Location =

new Point(28, senderNameY + y);

l1.Font = myFont;

//l1.BackColor = Color.Transparent;

l1.Width = 200;

this.Controls.Add(l1);

Label l2 = new Label();

l2 =

new Label();

l2.Name =

"display" + "_" + dname;

l2.Text =

"";

l2.Location =

new Point(27, displayAndButton + y);

l2.Font = myFont;

//l2.BackColor = Color.Transparent;

l2.Width = 200;

this.Controls.Add(l2);

ProgressBar p = new ProgressBar();

p.Name =

"progressBar" + "_" + dname;

p.Location =

new Point(30, progressBarY + y);

p.Height = 15;

p.Width = 463;

p.Maximum = 100;

//p.BackColor = Color.Transparent;

this.Controls.Add(p);

Button b = new Button();

b.Name =

"cancel" + "_" + dnameCancel;

b.Location =

new Point(385, displayAndButton + y);

b.Text =

"Cancel";

//b.BackColor = Color.Transparent;

//b.Click += new EventHandler(picBtnCancel_Click);

b.Click +=

new EventHandler(b_Click);

this.Controls.Add(b);

//fileID = fileID + 1;

//Add File Open Button

Button ob = new Button();

ob.Name =

"Open" + "_" + dname;

ob.Location =

new Point(200, displayAndButton + y);

ob.Text =

"Open File";

//ob.BackColor = Color.Transparent;

ob.Visible =

false;

ob.Click +=

new EventHandler(ob_Click);

this.Controls.Add(ob);

//End File Open Button

y = y + 90;

return true;

}

catch (Exception exc)

{

return false;

}

// }

}

//---End Code---

Waiting for you kind reply,
Thanks

Hi,
Post your code using insert code block located near by html icon in the toolbar.

Hi,
I cant not able to workout your code .but from your code i understand everytime you creating a set of controls.instead of doing like that create a user control.whenever you want you add it at run time.

Thanks Gnanadurai for your continuous replies.
Yes, everytimei am creating a set of controls at runtime. You mean the code is not workable for you or you could not understand it well.
Here is the code snippet:

public bool addNewControls(string senderOrReciver, string fromUser, string fileName, string ToUser)
        {
            try
            {
                FontFamily ff = new FontFamily("Verdana");
                float size = float.Parse("8.25");
                FontStyle objFS = FontStyle.Bold;
                Font myFont = new Font(ff, size, objFS);
                string dname;
                string dnameCancel;              
                
                
                
                if (senderOrReciver.Trim().ToString() == "Sender :")
                {
                    dname = fromUser + fileName;
                    dnameCancel = fromUser + "=" + ToUser + "=" + fileName;
                }
                else
                {
                    dname = ToUser + fileName;
                    dnameCancel = "Rec" + fromUser + "=" + ToUser +  "=" + fileName;
                }

                Label l = new Label();

hello Gnanadurai.
I used your idea of putting all the controls i am creating at runtime in a user control and added that user control on the form but it did not solve my problem.
Actually, the layout of the form with scroll bargets disturbed when controls are added one by one. But when i add controls using FOR loop (1 to 50), it works fine.
But my scenario is to add controls one by one by showing a confirmation window to the user and then user clicks on a button to add the runtime controls.
Do you have any other idea of how to get rid of this problem?
Waiting for your kind reply,
thanks
