        }
       SqlCommand com = new SqlCommand("gridcolor", Connection);
       com.CommandType = CommandType.StoredProcedure;
       com.Parameters.AddWithValue("@colorId", colorId);
       com.Parameters.Add("@color", SqlDbType.NVarChar, 30);
       com.Parameters["@color"].Direction = ParameterDirection.Output;
       com.ExecuteNonQuery();
       string msg = (string)com.Parameters["@color"].Value;
           foreach (GridViewRow rows in GridView1.Rows)
           {
              //here I need the condition to filter each rows with different color
              //  which I assigned in db
               GridView1.RowStyle.BackColor = System.Drawing.Color.FromName(msg);
           }
           con.Close();
       }

What are you trying to achieve? Do you want to set back color for row depending on values returned by query?

Use GridViewRowEventArgs e passed into GridView1_RowDataBound procedure:

C#

if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.BackColor = Color.FromName(StringValueReturnedByQuery);
        }

But before... have a look at below SP:

SQL

CREATE proc [dbo].[gridcolor]
    @colorId bigint,
    @color nvarchar(40) output
AS
BEGIN
    SELECT @color=color
    FROM status
    WHERE colorId=@colorId

    RETURN @color
END

Hello,

OnDataRowBound Event you can set the color of row based on your condition.

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                e.Row.Style.Add("background-color", "#000");
            }
        }
