Checkbox array question (Program stops responding)

[Jakes]

I need to associate the elements of a bool type matrix with the state of a checkbox from an array that i've created. For example: if the element checkBoxMatrix[3,4] is checked then the the element in boolMatrix[3,4] is changed to true and if it is unchecked it is changed to false. However; this is not my problem.

The size of the matrices aren't fixed. I dynamically allocate the number of rows and columns.It works fine when the ranges are small, but when these ranges become kind of big, for example 100 by 100, the program stops responding.

I would like to stick with the array of checkboxes since I'm kind of new with C#, but creating a table (like in Exel, if there is a way) on the form would suffice.

Any and all ideas are welcome...

Could you please post the code that you are using to dynamically allocate the memory for your arrays?

Are you sure that you are properly cleaning up the memory once you are finished with it?

(Is this a web application or desktop application?)

****This is the code where I create the array:

this.ActCondState=new System.Windows.Forms.CheckBox[this.ruleType.GetNumOfRules(),this.ruleType.GetNumOfAct() + this.ruleType.GetNumOfCond()];
 
j=40;
 
this.checkBoxDimension1 = this.ruleType.GetNumOfRules();
this.checkBoxDimension2 = this.ruleType.GetNumOfAct() + this.ruleType.GetNumOfCond();
 
//Creates the checkboxes which maintain the state of each entry in the decision matrix
for(k=0;k<this.checkBoxDimension1;++k)
{
     int o=30;
     for(l=0;l<this.checkBoxDimension2;++l)
     {
        this.ActCondState[k,l] = new System.Windows.Forms.CheckBox();
        if(this.ruleType.GetDecisionMatrixElem(k,l) == true)
    this.ActCondState[k,l].Checked =true;
        this.ActCondState[k,l].CheckStateChanged += new EventHandler
        mainFrm_CheckStateChanged);
        this.ActCondState[k,l].Location = new System.Drawing.Point(j,o);
        this.ActCondState[k,l].Size =new System.Drawing.Size(30,20);
        this.ActCondState[k,l].Name = "ActCondState"+k+"_"+l; 
        this.RuleTypePopulateTab.Controls.AddRange(new
        System.Windows.Forms.Control[]  {this.ActCondState[k,l]});
        o+=20;
      }
      j+=40;
}
 
//****This is the code where i dispose of each individual checkbox:
 
if(ActCondState != null)
{
          for(k=0;k<this.checkBoxDimension1;++k)
    for(l=0;l<this.checkBoxDimension2;++l)
    {
          this.ActCondState[k,l].Dispose();
    }
}
 

Thank you for your response

Oh, and its a desktop application.
