hi

Why do I want to uncheck all the form checkboxes, but the regular checkbox is done ?!

 

 

my code is

void ClearForm(GroupBox control)
        {
               
            
                foreach (Control chexkBox in control.Controls)
                {
                    if (chexkBox is CheckBox)
                    {
                        ((CheckBox)chexkBox).Checked = false;

                    }


                }

                foreach (Control textBox in control.Controls)
                {
                if (textBox.GetType() == typeof(TextBox))
                    {
                        ((TextBox)textBox).Text = "no";

                    }

                }
            

           


        }

hi mr dinko

The above telerik checkboxes do not remove their check, but the Visual Basic checkbox itself is removed.

Hello ebrahim,

Thank you for the provided code snippet.

I am not exactly sure that I have fully understood your approach. May I ask you to share your structure so that I can replicate it on my side? You can also elaborate more on what is not working.

I am looking forward to your reply.

Hi ebrahim,

Thank you for the provided image.

To uncheck the items inside the RadCheckedListBox, you need to use the Items collection property of the control. Basically, the control derives from RadListView and you can directly get the checkboxes inside the ListViewDataItem. However, the ListViewDataItem exposes the CheckState enumeration property which I think is what you are looking for. You can check the following code snippet which will better demonstrate what I have in mind.

private void radButton1_Click(object sender, EventArgs e)
{
    foreach (Control element in this.Controls)
    {
        if (element is RadCheckedListBox)
        {
            foreach (var item in (element as RadCheckedListBox).Items)
            {
                if (item.CheckState == Telerik.WinControls.Enumerations.ToggleState.On)
                {
                    item.CheckState = Telerik.WinControls.Enumerations.ToggleState.Off;
                }
                else
                {
                    item.CheckState = Telerik.WinControls.Enumerations.ToggleState.On;
                }                        
            }
        }
    }
}

Give this approach a try and let me know how it goes.
