Following code does validation I believe.Now when a submit button is clicked i want the validation to happen and if its true then save the result and show a message to user like" completed successfull" but even if one of the boxes is not checked then return false and show a message like " you have to check each box". Now what should i write in the method protected void Button1_Click(object sender, EventArgs e) ?

C#

bool itischecked = false;
        public bool isCheckboxSelected()
        {
            for (int i = 0; i < CheckBoxList1.Items.Count; i++)
            {
                if (!CheckBoxList1.Items[i].Selected)
                {
                    return itischecked;
                    
                }
                 
                    
            }
            itischecked = true;
            return itischecked;
        }

protected void Button1_Click(object sender, EventArgs e)
        {

        }

I would do it like this:

C#

public bool isCheckboxSelected()
{
    foreach (var item in CheckBoxList1.Items)
    {
        if (!item.Selected)
        {
            return false;
        }
    }
    return true;
}

protected void Button1_Click(object sender, EventArgs e)
{
    var result = isCheckboxSelected();
    if (result)
    {
    // do your data update
    }
    else
    {
    // Show your Errormessage
    }
}

1.

C#

string messageText = isCheckboxSelected() ?
"completed successfull" :
"you have to check each box";

MessageBox.Show(messageText);

2.

C#

if(isCheckboxSelected())
{
MessageBox.Show("completed successfull");
}
else
{
MessageBox.Show("you have to check each box");
}

I think first variant is prefered.

While your validation check may work there are a few redundancies there. the bool isitchecked is not really necessary. You also do not check whether the Item is a CheckBox. I would try something like this

C#

public bool AreCheckBoxesSelected()
        {
            for (int i = 0; i < CheckBoxList1.Items.Count; i++)
            {
                if (CheckBoxList1.Items[i] is CheckBox)
                {
                    if (!CheckBoxList1.Items[i].Selected)
                    {
                        return false;
                    }
                }
            }
            return true;
        }

        protected void Button1_Click(object sender, EventArgs e)
        {

            if (AreCheckBoxesSelected())
            {
                SaveResult();
                MessageBox.Show("Success ..... Yaaaaaaay");
            }
            else
            {
                MessageBox.Show("No Joy. Ensure all Check Boxes are CHECKED please.");
            }
        }

This assumes that you have a Method SaveResult which would save the result?

Hope this helps

Try this,

C#

//Add a label to your page with color red. say lblErrorMessage.

protected void Button1_Click(object sender, EventArgs e)
{
if(!isCheckboxSelected)
{
lblErrorMessage.Text = "you have to check each box"
return false;
}
else
{
lblErrorMessage.Text = "completed successfully"
}
}
