Please can any one help me out with this problem.
I have the following code in my button click event.

I need to add item from my textbox to the gridview, but when I click the button, instead of displaying the values on the datagridview, it counts and display the length of each string in the textbox.

Please, how do I sort this out

private void btnAdd_Click(object sender, EventArgs e)
{
    List<string> items = new List<string>();
    items.Add(txtItem.Text);
    items.Add(txtName.Text);
    items.Add(txtAddress.Text);
    items.Add(txtState.Text);
           
    DGV.DataSource = items.ToList();
}</string></string>

This is happening because gridview is allowing you to bind to a property .... ironically the string object only has one property "Length" :)

one way you can solve it is create a wrapper class for your values like

C#

class stringWrapper
        {
            public string StringValue { get; set; }

            public stringWrapper()
            { }

            public stringWrapper(string str)
            {
                this.StringValue = str;
            }
        }

the you can write your code now just modified as

List<stringwrapper> items = new List<stringwrapper>(); 
    items.Add(new stringWrapper(txtItem.Text));
    ......
    DGV.DataSource = items;
</stringwrapper></stringwrapper>

unless you wish to bind and utilize the benifits there ... I would just go with Answer 1

Yes the Perfect Solution is to make a New StringWrapper Class and make a List of it.....

some what this way....

public class StringWrapper
     {
        string text;
        [Bindable(true)]
        public string Text
        {
            get
            {
                return text;
            }
        }
       public  StringWrapper(string s)
       {
           text = s;
       }
     }

then use your List this way

List<<StringWrapper>> l = new List<<StringWrapper>>();
           l.Add(new StringWrapper(textBox1.Text));
           l.Add(new StringWrapper(textBox2.Text));
           l.Add(new StringWrapper(textBox3.Text));

           dataGridView1.DataSource = l.ToList<<StringWrapper>>();<stringwrapper>();</stringwrapper>

Hope this will help you and Sorry if this is a silly answer.... thanx guys for sharing your experience and needs.......

Of the top of my head, I can't think of a simple answer. I can sort of see why it happens, but it would make more sense if it didn't.
Any way, you can do it by not having the list at all:

dataGridView1.Columns.Add("Col1", "Column 1");
dataGridView1.Rows.Add("Hello");
dataGridView1.Rows.Add("Welcome");
dataGridView1.Rows.Add("GoodBye");

or by iterating though your list.

List<string> list = new List<string>();
list.Add("Hello");
list.Add("Welcome");
list.Add("GoodBye");
dataGridView1.Columns.Add("Col1", "Column 1");
foreach (string s in list)
    {
    dataGridView1.Rows.Add(s);
    }</string></string>

Either way, you will need to manually back-modify any changes into the textboxes from the datagridview
