help w homework (usercontrol)

this is the task i got: "Program starts with 2 forms: Dog and Cat (pink). Each form has: -arrUC: 2 yellow UserControl1s (each holds Labels). -Labels: Min_Max_label (“Min/Max”), Image_Text_label (“Image/Text”), bySize_byBrightness_label (“bySize/byBrightness”). -Rule: “Text” → “bySize”, “Image” → “byBrightness”. -RadioButtons: Red / Green. -MinMax_Result_label: small white label for results. Each UserControl holds an array of Labels with random size, Name (Dog/Cat), and one of 8 defined styles (Dog/Cat, Red/Green, text or image). Section A (Clicks 1 & 2): On click → collect Labels into CatList / DogList. Filter by chosen RadioButton color (background for text, image color for image). Find Min/Max Label by Min_Max_label + criteria (bySize = area / byBrightness). Show result in MinMax_Result_label on both forms. Section B (Clicks 3 & 4): As a continuation of Section A, all controls from two filtered UserControls • Should be sorted according to the “by Size” or “by Brightness” text of bySize_byBrightness_label • Should be displayed in the two UserControls selected by the mouse clicks. Note: Sections can be combined so that after clicks, both the Min/Max and the sorted order are shown." Im in section B and I got stuck at a part in my code because whenver i press on my usercontrol i need it to kind of align in one after the other whetere its byasize or bybrightness, but when i click on it just kind of gets arranged one on top of the other... can someone help (i attached a vid of what hppend)? code : https://paste.mod.gg/zmpfmzbnlucm/0

how are you setting the position of the moved element?, are you keeping track of the element's width size when your moving and setting the position of the elements? also this is winform right? if its winform use something like a wrap panel to store ur elements when you move them, if not you have to keep track of all your element's size(width), like create a integer/float variable and each time you move a element, you add += (the element's width), and when you move and set the position of a element you use that float/int variable + (with a offset if u want (optional)), something like element.location = new (0, totalwidth + offset) oh just realized it is a winform use a wrap panel and add ur element to that wrap panel so it aligns one after the other

But I already did it in the code @🕊 ILoveBirds 🕊

🕊 ILoveBirds 🕊•2w ago

it seems the issue is with the label's width it doesn't update when you write more text u should set 'AutoSize' to true for the label lemme just whip up some code

🕊 ILoveBirds 🕊•2w ago

// total width & offset
int totalWidthAndOffset = 0;


// loop
for (int i = 0; i < 10; i++)
{
    // create a label & enable AutoSize
    Label label = new Label();
    label.Font = new Font(FontFamily.GenericSansSerif, 18);

    label.AutoSize = true;

    // set a random text
    string[] strs = new string[] { "Cat", "Dog", "Bird" };
    label.Text = strs[new Random().Next(0, strs.Length)];
    
    // add control to winform
    this.Controls.Add(label);


    // set control location
    label.Location = new Point(totalWidthAndOffset, 5);

    // NOTE: very important, you should read the width after adding the control to your winform or panel
    int widthLabel = label.Width;

    // total width and offset
    totalWidthAndOffset += widthLabel + 0;
}

// total width & offset
int totalWidthAndOffset = 0;


// loop
for (int i = 0; i < 10; i++)
{
    // create a label & enable AutoSize
    Label label = new Label();
    label.Font = new Font(FontFamily.GenericSansSerif, 18);

    label.AutoSize = true;

    // set a random text
    string[] strs = new string[] { "Cat", "Dog", "Bird" };
    label.Text = strs[new Random().Next(0, strs.Length)];
    
    // add control to winform
    this.Controls.Add(label);


    // set control location
    label.Location = new Point(totalWidthAndOffset, 5);

    // NOTE: very important, you should read the width after adding the control to your winform or panel
    int widthLabel = label.Width;

    // total width and offset
    totalWidthAndOffset += widthLabel + 0;
}

the above code creates 10 labels makes the font size a bit bigger and enables auto size for the font, sets a random text and aligns them one after the other note(important) read the label's width after adding it to the win form
