ASP.NET Public Property - Can't get value from User Control

I am working with a user control that is used as a selection criteria.  I need to have a checkbox depending on if a certain criteria is selected.  I have this working.  On the main form, I need to validate so I thought I would use public properties.  When checking the properties they values are false even though I set them to true.

//USER CONTROL CODE
 private short GetSelection()
        {
            short iSelection = 0;
            int iPlanc = 0;

            if (ViewState["Planc"] != null)
            {
                iPlanc = Convert.ToInt32(ViewState["Planc"]);
            }

            RowSelectorColumn myColumn = RowSelectorColumn.FindColumn(dgPlan);
            if (myColumn.SelectedIndexes.Length > 0) 
                iSelection = Convert.ToInt16(dgBenefit.DataKeys[myColumn.SelectedIndexes[0]]);

            if (iSelection == iPlanc)
            {
                this.pnlValidate.Visible = true;
                bValidate = true;  //Have been declare private above
                bValidChecked = false;  //Have been declare private above
            }
            else
            {
                this.pnlValidate.Visible = false;
                bValidate = false;  //Have been declare private above
                bValidChecked = false;  //Have been declare private above
            }

            return iSelection;
        }

        protected void chkValid_Checked(object sender, EventArgs e)
        {
            if (this.chkValid.Checked)
                bValidChecked = true;
            else
                bValidChecked = false;
        }

        public bool ValidChecked
        {
            get
            {
                return bValidChecked;
            }
        }

        public bool Validate
        {
            get
            {
                return bValidate;
            }
        }

Open in new window


//CODE IN MAIN FORM THAT INHERITS THE USER CONTROL
    protected void lnkNext_Click(object sender, System.EventArgs e)
    {
        try
        {
            lblMessage.Text = string.Empty;
            
             //User Control - Always returns False
            if (SelectionGrid1.Validate == true)
            {
                if (SelectionGrid1.ValidChecked == false)
                {
                    lblMessage.Text = "You must blah blah blah to continue.";
                    return;
                }
            }
        }
        catch (ApplicationException ex)
        {
            lblMessage.Text = ex.Message;
            return;
        }
    }

It is just as easy to just have your ValidChecked property return the state of the checkbox:
public bool ValidChecked
{
	get { return this.chkValid.Checked };
}

The problem is that the checkbox MUST be checked only if ONE out of "n" is checked.  That value of one is stored in the web.config file.  When it matches then I need to check the value of the check box.

if (iSelection == iPlanc) is comparing the Selection to the value stored in the web.config (iPlanc - which I stored in ViewState)

I solved it by storing the variables in Viewstate this way it retains its value.  

The properties work as designed now.
