I am using CKEditor to enter details (The details contains html elements). after that the details will be bind into a grid. In this I want to show the details without html tags in tooltip.

C#

protected void grdStepMain_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        int i = 0;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            foreach (TableCell cell in e.Row.Cells)
            {
                i++;
                string description = cell.Text;
                if (cell.Text.Length > 8 && (i == 2))
                    cell.Text = cell.Text.Substring(0, 8) + "....";
              string newdescription = Regex.Replace(description, @"<[^>]+>|&nbsp;", "").Trim();
              cell.ToolTip = newdescription;
            }

        }
    }

But its not working please help me. Example:

CSS

string str= " &lt;h1&gt;&lt;span style=&quot;font-family:courier new,courier,monospace&quot;&gt;&lt;strong&gt;457457&lt;/strong&gt; 544444444444457457457&lt;/span&gt;";

The result in tooltip should be 457457544444444444457457457

Are the tags in the string actually made of HTML Entities, as in your example?

In your comment, you said that the HTML tags are actually made up with HTML Entities. In that case, a regex that matches from < to > won't work; you need a regex that matches from < to >:

C#

string newdescription = Regex.Replace(description, @"&lt;.+?&gt;|&nbsp;", "").Trim();
