How to select(changing color) dynamically created button in continuous way without skip

I have dynamically created buttons, eg 1,2,3,4,5,6,7,8; if I select 2,3,4, then I can't select 6 and skip 4. Or you can say, if I select 2,3,4,5,6 then if want to deselect 4 then I have to deselect 5 and 6 first.
private void GetControls()
{
count++;
for (int i = 10; i < 12; i++)
{
for (int j = 0; j < 60; j += 15)
{
Button btn = new Button();
btn.Text = i + "-" + j;
btn.ID = i + "." + j;
btn.Command += new CommandEventHandler(this.btn_Click);
// btn.Click += btn_Click;
flag = true;
btn.CommandName = i + "-" + j;
if (count==1)
{
PlaceHolder1.Controls.Add(btn);
List<string> createdControls = Session["Controls"] != null ? Session["Controls"] as List<string> : new List<string>();
if (!createdControls.Contains(btn.ID)) createdControls.Add(btn.ID);
Session["Controls"] = createdControls;
}
}
}
}
private void btn_Click(object sender, CommandEventArgs e)
{
count++;
//ResetButton();
Button btn = sender as Button;
string ID = (sender as Button).ID;
string text = (sender as Button).Text;
ResetButton(Convert.ToDouble(ID));
Label1.Text = " Congrates! Your meeting time has been sheduled between " + ID;
} //}
private void ResetButton(double selectedButtonID)
{
List<string> createdControls = Session["Controls"] != null ? Session["Controls"] as List<string> : new List<string>();
TimeSpan timespan = TimeSpan.FromHours(selectedButtonID);
string currentSelectedTime = timespan.ToString("h\\:mm");
foreach (string buttonID in createdControls)
{
if (!string.IsNullOrEmpty(buttonID))
{
int comparisonResult = timespan.CompareTo(TimeSpan.FromHours(Convert.ToDouble(buttonID)));
Button button = Page.FindControl(buttonID) as Button;
if (button != null && comparisonResult >= 0 )
{
if (button.BackColor == Color.Yellow)
{
button.BackColor = System.Drawing.Color.GhostWhite;
}
else if (button.BackColor == Color.GhostWhite)
{
button.BackColor = System.Drawing.Color.GhostWhite;
}
else
{
button.BackColor = System.Drawing.Color.Yellow;
}

I want to create dynamic textbox and ImageButton on Button Click Inside dynamic gridview cell

lt.Text = "<br />";
pnlStartDate.Controls.Add(lt);
}
}
}
}
break;
}
}
}
}
But the problem is in RecreateDateControls() function ImageButton Counter cnt2 is zero therefore previous controls are not recreated what should i do for it.

How to interact with variables (just created in the program) that are in another method?

In the first method I'm creating a matrix of textboxes and in another (Button_click) method. I need to take the values of textboxes from the Button_Click method and then do something with them. I don't know how interact with just created values(the names are also new). But I know that I can't use t[j].
private void vsematrici_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
int selectedIndex = vsematrici.SelectedIndex+2;
StackPanel[] v = new StackPanel[selectedIndex];
for (int i = 0; i < selectedIndex; i++)
{
v[i] = new StackPanel();
v[i].Name = "matrixpanel" + i;
v[i].Orientation = Orientation.Horizontal;
TextBox[] t = new TextBox[selectedIndex];
for (int j = 0; j < selectedIndex; j++)
{
t[j] = new TextBox();
t[j].Name = "a" + (i + 1) + (j + 1);
t[j].Text = "a" + (i + 1) + (j + 1);
v[i].Children.Add(t[j]);
Thickness m = t[j].Margin;
m.Left = 1;
m.Bottom = 1;
t[j].Margin = m;
InputScope scope = new InputScope();
InputScopeName name = new InputScopeName();
name.NameValue = InputScopeNameValue.TelephoneNumber;
scope.Names.Add(name);
t[j].InputScope = scope;
}
mainpanel.Children.Add(v[i]);
}
Button button1 = new Button();
button1.Content = "Найти определитель";
button1.Click += Button_Click;
mainpanel.Children.Add(button1);
}
private void Button_Click(object sender, RoutedEventArgs e)
{
// Double sa11v = Convert.ToDouble(t[j].Text);
}
Sorry for my English, I'm from Russia :)

you could create a member variable that is used outside the event in which you have created TextBox Array-
TextBox[] _t = null;
private void vsematrici_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
int selectedIndex = vsematrici.SelectedIndex + 2;
StackPanel[] v = new StackPanel[selectedIndex];
for (int i = 0; i < selectedIndex; i++)
{
v[i] = new StackPanel();
v[i].Name = "matrixpanel" + i;
v[i].Orientation = Orientation.Horizontal;
_t = new TextBox[selectedIndex];
for (int j = 0; j < selectedIndex; j++)
{
_t[j] = new TextBox();
_t[j].Name = "a" + (i + 1) + (j + 1);
_t[j].Text = "a" + (i + 1) + (j + 1);
v[i].Children.Add(_t[j]);
Thickness m = t[j].Margin;
m.Left = 1;
m.Bottom = 1;
_t[j].Margin = m;
InputScope scope = new InputScope();
InputScopeName name = new InputScopeName();
name.NameValue = InputScopeNameValue.TelephoneNumber;
scope.Names.Add(name);
_t[j].InputScope = scope;
}
mainpanel.Children.Add(v[i]);
}
Button button1 = new Button();
button1.Content = "Найти определитель";
button1.Click += Button_Click;
mainpanel.Children.Add(button1);
}
private void Button_Click(object sender, RoutedEventArgs e)
{
if (_t != null)
{
//Do your work here
// Double sa11v = Convert.ToDouble(t[j].Text);
}
}
but for a broader aspect, you can use dictionary,
Dictionary<string, TextBox> _dicTextBoxes;
private void vsematrici_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
int selectedIndex = vsematrici.SelectedIndex + 2;
StackPanel[] v = new StackPanel[selectedIndex];
for (int i = 0; i < selectedIndex; i++)
{
v[i] = new StackPanel();
v[i].Name = "matrixpanel" + i;
v[i].Orientation = Orientation.Horizontal;
_dicTextBoxes = new Dictionary<string, TextBox>();
for (int j = 0; j < selectedIndex; j++)
{
TextBox txtBox = new TextBox();
txtBox = new TextBox();
txtBox.Name = "a" + (i + 1) + (j + 1);
txtBox.Text = "a" + (i + 1) + (j + 1);
v[i].Children.Add(txtBox);
Thickness m = txtBox.Margin;
m.Left = 1;
m.Bottom = 1;
txtBox.Margin = m;
InputScope scope = new InputScope();
InputScopeName name = new InputScopeName();
name.NameValue = InputScopeNameValue.TelephoneNumber;
scope.Names.Add(name);
txtBox.InputScope = scope;
_dicTextBoxes.Add(txtBox.Name, txtBox);
}
mainpanel.Children.Add(v[i]);
}
Button button1 = new Button();
button1.Content = "Найти определитель";
button1.Click += Button_Click;
mainpanel.Children.Add(button1);
}
private void Button_Click(object sender, RoutedEventArgs e)
{
if (_dicTextBoxes != null)
{
// a23 is the name of textbox, 'a' is prefixe, '2' is the 2nd stackpanel you have added
// '3' is the 3rd textbox you have added in stackpanel
if (_dicTextBoxes.ContainsKey("a23"))
{
//Do your work here
Double sa11v = Convert.ToDouble(_dicTextBoxes["a23"].Text);
}
}
}

Loop through the Children of mainpanel and check each control if it is a TextBox. Something like:
foreach (UIElement ctrl in mainpanel.Children)
{
if (ctrl.GetType() == typeof(TextBox))
{
TextBox oneOfYourTextBoxes = ((TextBox)ctrl);
// do your thing
}
}

You cannot change an arrays size after you created it. Hence your size is known only at runtime after firing your event you cannot set its size within the declaration.
class MyClass
{
Textbox[] myTextBoxes;
private void vsematrici_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
// ...
myTextBoxes = new TextBoxes[selectedIndex];
}
private void Button_Click(object sender, RoutedEventArgs e)
{
int myIndex = // your selected item here
if (this.myTextBoxes != null && myIndex < this.myTextBoxes.Length)
{
Console.WriteLine(this.myTextBoxes[myIndex].Text);
}
}
}

This will also work:
button1.Click += (sender, args) => DoSomethingToTextboxes(_t);

Runtime textbox creation creates issue

This code works fine for first two times,i.e ,when i click on "Add more solution" it creates a new row and controls respectively but when i click on "Add more solution" for the third time and "add step" button respective to that,,it creates problem.

How to increment values when add dynamic controls?

I am adding dynamic controls and I want to increment the values in Label when adding controls dynamically
Code:
private int controlCount
{
get
{
int val = 0;
try
{
val = (int)ViewState["ControlCount"];
}
catch (Exception e)
{
// handle exception, if required.
}
return val;
}
set { ViewState["ControlCount"] = value; }
}
protected void addnewtext_Click(object sender, EventArgs e)
{
int i = controlCount++;
for (int j = 0; j <= i; j++)
{
AddVisaControl ac = (AddVisaControl)Page.LoadControl("AddVisaControl.ascx");
Label lb = new Label();
string z = Convert.ToString(i + 1);
lb.Text = "Visa " + z;
rpt1.Controls.Add(lb);
lb.Attributes.Add("class", "style8");
rpt1.Controls.Add(ac);
rpt1.Controls.Add(new LiteralControl("<BR>"));
}
}
In the below image I'm getting label values i.e(Visa 3) are overwriting
Any ideas?

You want
string z = Convert.ToString(j + 1);
rather than
string z = Convert.ToString(i + 1);
