Why e.Row.Cells[2].Text always show "" or null in GridView1_RowDataBound event

Here is my code 

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow) {
        // DataRow data = ((DataRowView)e.Row.DataItem).Row;
        string ToolTipString = Convert.ToString(e.Row.Cells[2].Text);
        e.Row.Cells[2].Attributes.Add("title", ToolTipString);
        Label MyLabel = (Label)e.Row.FindControl("MyLabel");

        if (ToolTipString.Length < 20) {
            MyLabel.Text = ToolTipString;
        }
        else {
            MyLabel.Text = String.Format("{0}...", ToolTipString.Substring(0, 17));
            MyLabel.ToolTip = ToolTipString;
        }
    }
}

But Convert.ToString(e.Row.Cells[2].Text); here always gives me "". Is there anything wrong in my code?

Usually this problem happens when the Column is hidden on the Grid. Two steps to solve it,

  1. Instead of using Visible="false" use a css class for the bound field like this, ItemStyle-CssClass="Column_Hide"

  2. Create Column_Hide in css file,

    .Column_Hide
 {
    display: none;
 }

Hopefully your problem will be solved

Please use this code

var ToolTipString = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "Column"));
