This code is vulnerable for sql-injections! You should user sql-parameters instead of building your sql-query like that!

Solution 1

Try this:
You'll have to modify your loop also.. Style will not work in alert box. Try this:

C#

for (int i = 0; i < xDT.Rows.Count; i++)
{
    Data += xDT.Rows[i][3].ToString();

}
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Dialog", "alert('" + Data + "');", true);
