How to get location of a picturebox by clicking on it in C#?

3 New Member
Hi, i have a problem about picturebox control. if you may help me, i will be so happy. i have a picturebox named pic_map, and i added a button named customer_button , my wish is to add a new small picturebox on the map_picture and the new added picturebox should have click event to get the location of it when it is clicked.

i have written some code in C# but when clicking the small picturebox it just gets the location of the last added one, not the one that i clicked on .

here is my code:

pic_map: main picturebox

i global int, initial value=0
Expand|Select|Wrap|Line Numbers
  1. private void pic_map_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
  2. {
  3.        x=e.X;
  4.        y=e.Y;
  5.       if((e.Button==MouseButtons.Left)&&(tag==1))
  6.      {
  7.            i=i+1;
  8. musteri=new Bitmap("f:musteri_button.jpg");
  9. //                    node[j]=new PictureBox();
  10. //                    node[j].Image=musteri;
  11. }

Hi, i have a problem about picturebox control. if you may help me, i will be so happy. i have a picturebox named pic_map, and i added a button named btn_customer to my form, my wish is to add new small picturebox to the coordinates that the user click on the pic_map and the new added picturebox should have click event to get the location of it when it is clicked and also be a member of the picturebox array.

after clicking the btn_customer, the coordinate thet user click on the pic_map there should be added a new picturebox with a tag number increasing 1 every time.

i have written some code in C# but when clicking one of the small picturebox it just gets the location of the last added one, not the one that i clicked on .

here is my code:

Expand|Select|Wrap|Line Numbers
  1. pic_map: main picturebox
  2.  
  3. i global int, initial value=0
  4.  
  5. musteri=new Bitmap("f:musteri_button.jpg");
  6. PictureBox [] node; //global
  7.  
  8. private void pic_map_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
  9. {
  10.        x=e.X;
  11.        y=e.Y;
  12. node=new PictureBox[50];
  13.       if((e.Button==MouseButtons.Left)&&(tag==1))
  14.      {
  15.          i=i+1;
  16.         node[j]=new PictureBox();
  17.         node[j].Image=musteri;
  18.        node[i].Size=new System.Drawing.Size(36,26);
  19.        node[i].Location=new System.Drawing.Point(x,y);
  20.        node[i].Visible=true;
  21.        node[i].Name="node"+i;
  22.        node[i].Click += new System.EventHandler(this.node_Click);
  23.        node[i].Tag=i;
  24.        this.pic_map.Controls.Add(node[i]);
  25. private void btn_customer_Click(object sender, System.EventArgs e)
  26. {
  27.     tag=1;
  28. }
  29.  
  30. private void node_Click(object sender, EventArgs e)
  31. {
  32. int a,b;   
  33.    a=node[Convert.ToUInt32(((PictureBox)sender).Tag)].Location.X;
  34.    b=node[Convert.ToUInt32(((PictureBox)sender).Tag)].Location.Y;
  35. }
Please help me, thanks for your consider....

An if statement runs only once and you want to run a loop. HTH.

Thanks, i have tried to use a loop, but could'nt find a way to get the clicked location while in the loop, if i define the x, y coordinate by manuel it works, but it does'nt allow getting the coordinates from picturebox while looping, or i could'nt find a way...

if you have an idea please confirm, thanks again

Hello. I want to render in a picturebox (pbD3DSurface) using DirectDraw. This is working more or less but the coordinates are always screen oriented and not pictureBox oriented. x = 10; //+this.Location.X+this.pbD3DSurface.Location.X; y = 10; //+this.pbD3DSurface.Location.Y+this.Location.Y; back.DrawCircle(x, y, 5); //back = surface

Dear All, This may sound like an elementary question but how do you implement scrollbars for the Picturebox control. Do I have to create my own code to do this or is there some property that I can set? Thank you very much for your time and consideration in this matter! Christopher Koeber

I want to create arrows using lines on a picture in the picture box. On clicking the button "btnShowAll", the image is loaded and the lines drawn. "RGSShowAll()" calls "DrawObjs()" which does the actual drawing work. But after displaying all the arrows in a flick, the arrows disappers. I have debugged and came to know that the "Paint" event of the picturebox is refreshing the image, so the work done on the CreateGraphics created object is...

I have a picturebox on my VB.NET form. The picturebox size mode is set to stretched. I then load an image into that form and display it. As the user moves the mouse over the form, I want to get and display (in the status bar) the image coordinates of the mouse location. However, if I use the picturebox's MouseMove event, I am getting the coordinates of the mouse over the PICTUREBOX, not the actual image underneath that (which is stretched)....

Hi there, Is it possible to create an array of picturebox controls during run-time. I wish to create a new image/picturebox everytime a user clicks the button on a form, and they need to be objects so that the user can move/drag them around. The only examples I can find dont work as I am using VB Express (2005?)

Hi All, I have a pictureBox control inside of a panel control. The pictureBox is larger than the panel control and I have the panel control set true for AutoScroll so the panel displays scrolling bars. I would like the user to be able to click and drag the image and for it to move around within the panel control. How would I do this?

XP VB 2005 running an example from help that creates a picturebox in code - the picturebox is not created. If I comment out the "Dim Box as New PictureBox" and create it in Design mode - the example works. I have tried Show, Enabled, Visible, and even BackColor. Why does a help example not work? and why does Design creation work? Thanks - I hope.
